oops, wrong footswitch

OK, another less-than-ideal "surprise" from this old VTX amp.  Yes, it came with *a* footswitch; but not the right one.  Having only three buttons instead of four was, I suppose, a giveaway.

Turns out, this footswitch can only control the reverb and the phaser (and the third button does nothing).  It's from some other Peavey amp, I guess.  Same unusual DIN-type connector, so I could even theoretically make it work fully, by drilling a hole for a fourth switch.  Or, I wouldn't mind if a single switch ("effects") controlled both reverb and phaser.  In all likelihood, I'll use the phaser almost never, and if I do, it would likely be for some weird sound experiments in a recording, not live.  But it's a real drawback that there's no footswitching for the two channels: which would need two buttons, to permit the unusual "combined" mode which Peavey makes available.

Yep, I think I may as well rewire this three-button footswitch so that it can do the proper channel switching.  Then I'll either combine reverb and phaser on one button if that's feasible, or else just switch reverb only and disable the phaser by turning the depth down to 0, same as when no footswitch is attached.

(I used this amp when I first got it for free, about 10 years ago, but I didn't remember a bunch of the details such as this; especially, because I was mainly using it as a clean power amp downstream of a little Behringer mixer, combining already-processed guitar (*) and digital pipe organ: so beyond verifying functionality, I didn't use the guitarish features of the VTX much.)

(* It's not that I wouldn't be caught dead getting my guitar tone from a solid-state Peavey preamp... oh wait, actually it is that.)

final interconnection, first power test

Connecting the new circuitry to the VTX chassis.  Most connections are through the 12-position "Euro" terminal strip, except heater power (to the left) which is hard-wired. First power-up, with no tubes inserted.  LEDs ahoy!  This just verifies that the +15V power supply is working, and I haven't made any grievious errors in the wiring. I verified that the channel-select 3-way switch works, turning on and off the yellow and green LEDs on the VTX, and the preamp-select 3-way works, turning on and off the white LEDs (yes, those are white, not blue as they appear in the camera). And I verified that the HV supply works, by taking it out of standby and observing that the blue LED of the RGB pilot light illuminates.  (It's a bit dim with the 10M resistor though, I guess I need to decrease the resistance; gotta take care with the power dissipation...)

schematics of my mods

  Again, caveats from the previous post apply here as well.  Most significantly, I have not yet built the boost circuit, nor even verified whether the VTX power transformer can handle the additional heater current load.  And some of the wiring of the phase inverter, vis a vis nfb, has not yet been implemented or tested.  So these circuits are to some extent, aspirational.
