    1. Re: Marshall Valvestate 8280 bi chorus schematic
      Andrew Baxendale

      : Hi. I need a schematic for a Marshall 8280 Bi-Chorus valvestate. Please contact me at [email protected].
      Could you supply me with a schematic?
      The amp seem to have low volume, I suspect the pre-amp section. Do you know if the single valve in the circuit is part of the pre-amp stage?

      : thanks

  1. Desperatly seeking Supra Schematics
    Jilly in trouble

    I can not live another day without schem. for a DOD FX55-c Supra distortion pedal. if you have it, or know where it is; don’t hesitate to tell me and i will be forever in your debt.

  2. Boss PH-2 Schematic
    Joel

    Does anyone have the Boss PH-2 Super Phaser Schematic? The problem I’m experiencing has to do with the power source when used with an adapter. It works fine with a battery but won’t run right using a 100mA or 200mA DC power source. Weird, it seems to need more power then it should when it’s bypassing the battery.Please Help if you can.Thanks alot

      : Hello
      :
      : I have a 5 knob Deluxe Memory Man with MN3005’s. Now i just opened it up and had a look at a schematic, here is what i have noticed on the PCB board.
      :
      : 1. 2x MN3005 and one spare socket
      : 2. 5x 4558
      : 3. 1x NE570
      : 4. 1x 5087
      : 5. 5x Trim Pots
      : 6. 1x 4047
      :
      : The MN3005’s are located on the top left of the PCB and the spare socket is the socket on the far left. And the two MN3005 are located to the right of that, under the three sockets are trim pots with a trim pot between the far right socket and the middle one
      : Now i am assuming that there is one MN3005 missing??
      :
      : If anyone has a picture of the the PCB could you please post it, or even a schematic, i have look at one schematic but it had more NE570’s etc…

        It is just normal. EH have built somme Delay with a third MN3005 Socket but normal are 2 MN3005. Maybe you can but a third BBD Chip inside to enlarge your delay time up to 615ms.

    1. Re: eletronic bypass circuit
      Pilo

      oi!
      For switching, you’ve got many solution. Passive one, with switch, but not very easy and good look, and active. For active, you can use the 4066 CMOS chip. They are very cheap, try to get the
      datasheet (easy to find), it’s 4 digital controled analog switch. Marshall in the VS100 use somme of them. But they’ve got bad dynamics. They are many version f this cheep, look for them. They are also
      a way, like the Mesa V-Twin (www.scheamticsheaven.com) with FET, I never try this. And the last solutin, wich is most use in Mesa and rivera amp, it’s to use LDR. look at mesa dual rect!

    1. Re: looking for a really long delay schematic

      : looking anywhere from 1 second and up if you have any please let me know..thankx

      easy….
      an ADC, DAC and memory…
      A clock to make the whole thing work, and gooo!! Cheap!
      If you want more, I’m working on a cheap multiFX processor… (so with very long delay, sampler!)

  7. rocktron gainiac problem
    ben sykora

    My gainiac sounds quite nice but after it warms up, the volume tapers off to a very weak signal. I replaced the 12ax7 and the problem remains. Changing power supply also did not help. Does anyone have a scematic or know about this problem in tube preamps?

      The tubes just need to warm up like every other tube product!!

        I think it’s a problem of the power voltage.
        If you have a voltmeter, plug it on the tube power, and see if when the sound go down the volatge go down. If it’s that, It may come in the power supply. Do you change it? or juste try? And what did you test? it may be a capacitor problem.

      1. Re: Guitar Effects/Schematics
        Zak Zub

        Mine’s broken too, but maybe you could have a look at yours and tell me where the "hot" wire to the Comp socket comes from on the PCB – just tell me what component(s) share the track.

        Here’s a few things you should check for:
        15-0-15 Vac at the transformer secondary
        +25 volts across the smoothing capacitor
        check that the LED isn’t blown (it’s in SERIES with the Vcc line to the rest of the pedal – try shorting it out and see if your pedal comes to life).
