Vypyr Schematics Collection

Vypyr DSP Board

Vypyr DSP Board

This page contains links to my collection of Vypyr schematics, photographs, and illustrations.  Please leave a comment if you find these useful.

PLEASE PLEASE PLEASE

If you have any pictures if the inside chassis of any of the Vypyr amps that I don’t have here please send a copy to Vypyr Schematics. Also, any missing schematics would be greatly appreciated. I’m looking for the Sanpera I schematic in particular, but a lot of the tube Vypyr schematics are missing from this collection as well. Recently added the schematics for the VIP 2 amplifier. There are some interesting similarities and some surprising differences between the classic Vypyr and the VIP designs. It is pretty obvious that Peavey applies some good process improvement in their design group.

Thanks go to WashburnTabu on the Peavy Vypyr Forum for collecting most of these.

    Hi,
    I have a problem with the power sponge popping and crackling when touched. It makes those sounds and cuts the volume dramatically. What would happen if i disconnect the power sponge wire? Would it affect anything?

    1. admin

      Sound like a loose connection to me. You might check the edge board connecter between the DSP board and the power sponge/Power amp first.

    good Collection…

    Have Vypyr 2 Vip 2 and if you turn the unit on all the lights flashing in sequence over and over again . Unplug input board and lights work like suppose to. So i replaced input jack assy. Still same problem can you give me some suggestion on cause.

    I mistakenly bought a Sanpera Pro foot controller, thinking it would work with my Vypyr 212 tube combo, but alas it does not The return data from the amp appears to work, but none of the buttons do anything. Is there anything that can be done about this? Some custom firmware that can be flashed? I have a Ground Control Pro, which works great, but the two expression pedals are what attracted me to the Sanpera.

    Glen,
    I just picked up a Vypyr 75 and it is dead. I have been trying for hours to get it going. The fuse was replaced and tests good with a multimeter. When I attempt to power on the amp, there is no light show and there is only a soft pop of the speaker when powered off. I have a mac and can’t seem to find out how to download the firmware update. Please let me know how I can fix this amp.

    Thank you!

      Good candidate to attempt reflashing. What part of the world are you in?

    hello glen i have a vypyr 3 that bricked on a bad download can i send the dsp board to you to fix it please

    Thanks much for this page! I own Vypyr T60 and I’d like to know if it is possible through sanpera’s midi make fx loop(send/return). Is it possible? Thanks for further answer.

    1. Glen

      MIDI is a serial digital protocol (no audio). If you are asking about an audio send/return to send the audio through a compressor or reverb or something like that, then no. It is not possible.

    Hey guys, ive got a problem with my vypyr 30. Its the original one that came out. I can play it for about 30 minutes before it stops outputting sound through the speaker. When that happens i can still hear it thriugh headphones, but no sound comes from the speaker. If i turn it off and leave it for another 30 minutes or so, the speaker works fine, but eventually stoos again. Has anyone had this problem before? I really like this amp so i would like to be able to fix it and use it again. Thanks for any helo you can give.

    1. Glen

      Sounds like the power amplifier is overheating (or the voltage regulator for the power board is overheating).

      Could be that the heat sinks for the voltage regulator or the amp chip aren’t physically tightly connected with lead paste. Try running with the chasis out of the cabinet and feel the VR and Amp chip when it shuts down. The one that gives you the second degree burn is the problem:)

  9. How about modifying the Sanpera 1.
    Would it be possible to add two foot switches to act like your pressing the 1&2 or the 3&4 foot switches on the Sanpera simultaneously?
    Because if I don’t get the 3&4 simultaneously for the looper then I have to re stomp it into aux mode & try again (The Sanpera’s are not really that balanced so every time you rock forward to ingage the main or aux the pedal lifts off the floor. So, I prefer not to have keep trying just to activate the looper.).

    Thanks.

  10. Are there any actual pictures of the boards available or just the drawings.
    I h
    I bought a VYPER 30, thinking that it had a USB (Because,the Peavey sticker on the Amp said the 30 Watt had ,”Studio Quality USB.”.
    I’m not good at schematics. So, if I could see the insides I’d have a better idea as to if I could get a USB board and just be able to plug it into the board on the Amp, cut a slot for the plug and call it good.
    Or, if I’ll have to do some soldering if it’s possible at all?

    1. Glen

      You can kind of see the board on the 60 and 75 watt chassis pictures HERE. The board has the aux input and headphone out jacks on it as well as the USB port. If you look, you will see that it has two ribbon cables that go to the DSP board. Your Vypyr DSP board does not have the header pins on it. Adding them involves unsoldering the pin holes on the board, then soldering in a new pin header. If you aren’t familiar with using a solder sucker you are probably not up to taking on this task.

      With the header pins soldered into the DSP board, the next step is to buy an aux/midi board and a USB ribbon cable from Peavey. I have not priced these recently, but they used to cost around $40.00.

      New Peavey board in hand, the next step is to fabricate a board mount in the chassis to hold the board and to drill holes for the Aux input, headphone out, and USB B connector somewhere in the chassis (nothing says they have to be on the front). If you aren’t familiar with metalwork in small chassis boxes I can assure you that this will end up looking like crap, so seriously consider mounting this on the back of the chassis instead of the front.

      As I said in my other response, the end result (Peavey USB connection to computer) truly is not a valid solution to recording your riffs. The only reason to consider doing this is for the novelty, not for the music.

  11. Would it be possible to put a USB on a Vyper 30.
    I bought one when they first came out. When I got it at the store I took it out the box and tested it (Before I paid for it.).
    It had a nice sticker on the front speaker that said, “VYPER 30 Watts Studio Quality USB.”
    I thought that I had to by a USB adapter to plug into the MIDI port (Computers were just starting to take leaps. So,I inquire about it.).
    After, I got a computer that I thought would be able to handle the systems requirements I started to look into how to take advantage of this “Studio Quality USB”.
    Even though it says that it has a Studio Quality USB (I still have the sticker on the side of the amp.) I can only find out that it is only available in the higher Watage VYPER Amps.
    So, would I be able to put a USB port on my 30 (Like it should of already had.)?

    1. Glen

      Is it possible? Yes, but the better question should be does it make sense. I’ve spent a lot of time and effort messing with recording using the Peavey USB port and can tell you from personal experience that the Vypyr USB implementation is not adequate for recording. It is limited, tends to be noisy, Is difficult to match signal levels with computer inputs and the list goes on.

      Assuming that you are looking for a USB connection to record direct from your amplifier, just say no. Reasonable audio interfaces are readily available that do a much better job at very reasonable cost that really work for recording (zero latency monitoring, proper impedance matching, headphone and line/computer outputs, etc.). Buy something like a Scarlett 2X2 audio interface and connect your Vypyr to it using the headphone out on the Vypyr to the Interface.

      Just recording your guitar riffs isn’t something that you can do much with. Once you’ve done it you will wonder why. Find a good DAW (Digital Audio Workstation) program for your computer and start doing your own multi-track recording. Lay down the rhythm for a song then play your leads to complete the song. You might even consider getting a good microphone to plug into the interface and do some vocals.

      Yeah, it is possible to solder in the USB jumpers in a Vypyr 30, change the model dip switch settings on the encoder board and buy/install a USB board from Peavey, and connect your Vypyr to your computer. My advice is that it isn’t worth the effort.

      Lots of good DAWs out there. If you have a Mac you already have one installed (Garage Band). I recommend Cakewalk products with Home Studio being a great starting point (about $60.00) or Reaper can be run in demo mode forever.

  12. Glen, You did a great job, I wanted to know if there is a way to add effects loop in this amp just after the AMP channel….so that we can put in Noise gate(that is just after the Amp’s drive), EQs, different analog effects…..followed by the amp’s inbuilt reverb and delay and then the output.

    Since you have studied the schematics it would be easy for you to state…just a little push in my direction of thought would be enough. Thank you, 😀 😀

    P.S.:Mine is Peavey Vypyr 30

    1. admin

      There is an effects loop mod that you should be able to find in the Peavey forum. This sits between the final DSP altered output and the power amplifier. Not quite what you are asking about, but it is about as close as you can get with DSP modeling I’m afraid.

      Glen

      1. Thanks a Lot glen 😀

  13. Glen,

    Thanks for all the information!

    I don’t know if this will help you or not but I’m looking at the main board from a silver Sanpera 1 and it has the same part number as the Sanpera 2 in your schematic.
    If it would be of any help I’ll compare and let you know what parts are not loaded on the 1.

    The reason I came across your site is that this Sanpera 1 (again an older silver one) does not light up with my daughters brand new VIP 3. Do you know if the older Sanperas are compatible with the new VIP’s.

    Again thanks for the info!

    1. Glen

      The Sanpera’s are all supposed to be compatible with the VIP amplifiers. You aren’t getting any lights on the Sanpera? I have had problems where the MIDI cable

      1) did not plug in all the way because the chasis on the amp interfered with the plug edges
      2) plugged in upside down (bending pins). The socket is ‘upside down’ on the Sanpera
      3) plugged in one pin sideways.

      Also, if you are not using a Peavey supplied cable you may want to check that all eight pins (and the shield) are connected through. Some eight pin cables are only wired for seven pins.

  14. Do you know which screws take the 75w chassis out? Would be much help if you coukd clarify here thank you!

    1. Glen

      There are four screws on the top of the amplifier. These are on the metal strips. These are long screws and must be completely removed to take the chassis out. No need to unscrew the handle. Then, on the back of the amplifier there are two screws holding the back of the chassis up.

  15. Hi.
    I have another problem
    One time im turn on my vypyr 30 but… Sanpera doesn`t work. It`s realy dead all is turned off (leds, pedal doesn`t work). I`ve tried to check cable but aslo with connection with midi slot signal passed but all is dead. Where is the problem?

  16. Hi

    Looking for some help with a VYPYR 30 amp, owner has been using aux out and headphones jack to run through computer

    we now have no output from the power amp (headphones
