I just purchased a MOD 102+ amp kit. It's supposed to be Fender Champ-ish (at least in tone) but uses an EL84 instead of a 6V6. When researching the kit before buying I came across a video from Dlabs where he had modded it to use a 6V6 instead. I saw a few other forum posts on this too and even one where it was being modded to have both and use a toggle to switch between the two. The problem is no one really explained exactly what they did.
I'm wanting to do something similar. I'd like to add an octal socket to have the option to use either EL84 or 6V6. But unlike the one person, not bother with the toggle switch and do it similar to how my N5X kit is done. In the N5X you put one tube or the other in, not both at the same time. Using the schematics from both amps I've combined them to something that I think would work.
My questions are:
This is the modification I worked up to add the octal socket
The original physical layout (heater wires aren't shown in this pic)

My questions are:
- Most importantly, would this actually work?
- What value cap and resistor would I use coming off pin 1/8 on the 6v6 socket?
- How would that lay out physically; specifically where would I connect the resistor/capacitor that come off of the 6v6 socket pins 1/8? This kit uses tag strips.
