I understand your pain - was googling for similar, and came across this post, 5 years prior. My SGC Nanyo Bass Collection has just started to play silly beggars with the pots, and a bridge fault. Nowhere online seemed to have any details of the wiring, as the problem is, as you say, the fact that all of the tone and volume pots are based on a printed circuit board. If theres a nick or short on the board, its a pig to replace, and I really wouldn't like to have to wire any pots onto it. I'm currently looking at the options of ripping out the old electrics and wiring it from scratch myself. If you're still after answers, good luck!

PS - noted that none of the previous replies are relevant to this - mostly going on about the amps or a Fender guitar??!

1. First remove the backplate from the BUP2 by undoing the two small screws at the base of the unit and lift out from the bottom so that the two lugs at the top disengage from their positions. 2. Prior to installing onto the backplate, insert the battery into the battery tray and ensure that positive + and negative - are correctly installed. The battery is a non-rechargeable lithium cell and in the event of power failure will protect your programme instructions for up to 365 continuous days of power loss. 3. The BUP2 is factory set to provide 2 on/off switching periods per day and each day will be the same, i.e. daily operation. To select the other styles of switching you will have to alter the dip switches which are to be found at the bottom rear of the unit into the relevant position for the style of operation you require.

For what it's worth, the Style AA was advertised in 1910 catalogs. I believe they continue to have been made for forty or so years after that. So any time between 1909 (when pianos started being labelled 'Behr Bros') through to around 1950 or so ,,,

You can see the catalog https://antiquepianoshop.com/online-museum/behr-brothers/#berh2

Is is just the knob has broken (in which case, buy yourself a new knob and replace the one that's there) or is the potentiometer shaft broken too? That's a much bigger job, that involves pulling the whole amp apart and replacing the pot --- you need to get an electronics tech to do it.

Google
mg series knobs
to find replacements --- they just push on.

Fender GDEC 3... | Answered on Feb 08, 2020


I fixed mine it had the same issue bye opening it up by taking the screws out and carefully open it up and look for any corrosion or buildup on the circuit board then take a q-tip and dip it into isopropyl alcohol rubbing alcohol and just clean up any corrosion on the boards then look for the ribbon cable connection that is connected to the display try pushing the connector in to make sure it's firmly set in there on both ends of it and put it back together. I don't know what caused the screen to not display the actual text because I bought it used at a swap meet but I tried this and it worked.

Try changing out the Pico fuse. Only 50cents from online West Florida Components. Buy a few. Mine went out twice. It is Item # F021. It is a .5amp (500 mA)fuse-green and looks like a resistor. Location on the circuit board is near the transformer and on back edge or board behind the 2 brown wires connecting to the board and to the side of the 4 diodes there. I left the bad fuse in place and soldered the new fuse to it's legs-a lot easier and does not damage the PCB.

Main thing to verify is that the particular footswitch and cable you have is specifically for that amp. If it is not the right one, that is your problem as there is very little compatibility among footswitches.
Looking at the schematic, plugging in JUST the cable shifts operation as you observed. This uses a crazy circuit in which AC is applied on the cable and the footswitch has a diode each direction that causes the amp to shift between the states. when you plug a bare cable in, it disconnects the internal diodes and switches for control at the amp, hence the signals float.
You should investigate the footswitch to make sure it is the right type with the diodes resistors and caps that is for the Fender Deluxe.

You can find the schematic for the amp here:

http://www.fender.com/support/amp_schematics/pdfs/Hot_Rod_Deluxe_Schematic.pdf

Look at the circuitry of the switches on the schematic at C8. Your pedal should have similar circuitry. Assuming your cable is good, the problem would be in the pedal itself.

There is damage/burnt at Transistor Q4 or Q3 or both. Usually followed by R8. Replace it.
Q3 = BC337 (SMD marked as 6C) NPN.
Q4 = BC327 (SMD marked as 5A/B/C/D) PNP.
R8 = 470 ohm (SMD marked as 471).
