Pleximan Tremoverb...update with layout

[Gaz]

...Remember the 1M reverb pot adds to the "separation" more than the 100k Fender pot would.

10thtx, what do you mean by this?

[10thTx]

The Fender has a 100k pot with 3.3M mixing resistor.

The 1-tube reverb originally had a 2.2M pot with 100k mixing resistor.

Hope that makes sense to you?

10thtx, thanks for the reply (and don't mean to derail the thread). I see how in tubeswell's schem the 3.3M resistor and 220K for a divider before the mixer stage, but I'm having trouble seeing how the 1MA reverb pot interacts with that divider and the wet/dry ratio. Thanks for any help here.

Is there a big difference between inserting the reverb like 10thtx did compared to the more standard Fender way? Pros and cons?

What reverb tanks did you use in your projects, 10thtx and tubeswell?

Standard Fender Princeton Reverb type replacements.

The decisions just got a bit easier to make. The donor amp I'm going to use only has enough tubes to make the one tube version. So I'm going to try your version after all, 10thtx.

What software do you use for those .sch files?

[tubeswell]

I was looking at the readings between the two halves of the first AY7

Ah, see it now. I'm guessing that was simply a typo mistake?

Duh! yes it was! TFT - Corrected voltages huh?

220k is an over zealous grid leak for the mixer stage - superfluous? - probably (given that there is a 470k/1M path for grid current). More AC load than necessary? probably - especially given the tone stack after the recovery stage. But it sounded good in that configuration especially when dimed.

I tried lots of ways of skinning the cat on this - re-built the amp a dozen times with different reverb configurations - this was the one I preferred the most. YMMV.

Something I like to do is put the standby switch immediately after the reservoir caps. (power tube plates supply)

This helps the inrush current when you take it off standby.

I finally managed to make a layout for this project. It might not be exactly as the schematic.
Haven't done this before, and I'd be glad if you all want to have a look at it. Every comment is appreciated.

[Lynxtrap]

Anyone...?
It would be really nice to get some input. There are couple of solutions you might describe as "different".
