Fender 65 twin reverb reissue mods

HI

I was wondering if anyone had any idea how to mod this amp so you can have reverb on the normal channel. I love this amp but I would like to be able to have the reverb on both channels.

Thanks

Join the two channels (where u see 220k resistors) after the Vibrato channel output cap 022 uF

More specifically -
1 Lift the leg of R34(220K) which connects to R11(100k) / V1b pin 6.
2 Solder in a link wire between V1b pin 6 and V2b pin 6.

You could then ground the free end of R34 for less gain or leave it hanging for more gain, or leave it hanging and link out R35, thereby driving the phase splitter harder, for a different power amp overload characteristic.
Get a tech to do this if you're not competent.
Peter.
