Hey Guys, I picked up a deluxe reverb a couple months ago and its time it got serviced, so i figured id just ask my tech to do the preamp tap. Would he know what to do if i printed out the diagram from waldos site? What exactly should i tell him to do and is there a way to tap it and still use it as a combo if i wanted to? sorry if this question was brought up before, but i couldn't see to find a straightforward answer. THANKS!

Wouldn't hurt to show the tech Waldo's switching-jack diagram, for this purpose. If you skip the switching arrangement and just make a simple tap to a standard jack (like I did), you can reconvert to a combo use simply by inserting a dummy plug (or a snipped-off cable end)into the jack.

This may help too, dunno how close the circuits are, but it may be a good starting point for your tech. Waldo posted a RI schematic for a twin with the values we figured out.

Thats sounds exactly what i want to do. Putting in the mid control sounds like a fantastic idea too.... I've also heard things about a bright cap in vibrato channel that should be clipped?
with the swicthing jack i show on the schem/layout, you can use the amp as a combo by removing the plug and reconnecting the speakers. no dummy plug needed.
as for the mid control, what i did was remove input 2 and moved the volume to to that hole, and rewired a mid control in the tone controls by sliding the bass knob where the volume was and placing the mid control where the bass was. this way when used as a combo the only function i lost was the use of input 2, which i never use.
