Dual Valvecaster?

But make it PedalPCB style to fit a 125b case.

Two 12AX* tubes in a 1590N1?


Toight like a Toigurrrr!

Haha. It is a squeeze. But I mocked it up in AutoCAD and they fit.

Yep I think it can be done without too much of a struggle.

The trickiest part will be keeping top mounted jacks and sticking to one of the standard drill templates.

Thankfully the rest of the circuit is fairly simple so it shouldn't be too bad.

I can send you the CAD drill templates I've thrown together so far. One is a 3 knob with a switch that turns the second tube on at "full" (1m resistor) with the gain pot only controlling the first tube. The other template is a 4 knob design with knobs that control each tube independently.

I'm going to try to throw a PCB-less one together shortly....with top mounted jacks....and see how it goes. I'd love to have the soldering simplicity of a PCB for it though lol.

These are the tube sockets i'm using. It looks like they should fit just above the top mounted jacks.

Need more hits on this one. I just hammered out a dual VC in a 125b case without a board....man it would have gone so much smoother with a board. There are so few components that you could even incorporate a latching circuit to accommodate a soft momentary switch instead of the clicky kind.

I've been trying to turn this into a PCB in KiCAD....but that's an art I have yet to perfect. If you fine folks at PedalPCB would be so kind as to make this awesome I'd buy one in a heartbeat.
