Hi Steve-

Could you share with me how you pad down the speaker signal on the Dearmond for a line out? A little sketch, ohms & watts and all that jazz?

I built an RT-5 circuit for my nephew to go with the les paul junior I got him last year for Christmas, I omitted the tremolo and used a 6aq5 (small bottle 7-pin) instead of the 6v6 for extra squishiness.

Well that little amp really knocked me out and I have an extra set of trannies around (power transformer courtesy of a dumpster-rescued webster wire-recorder!) so I'd like to build one for myself but add a line-out jack and send pot on the front panel to make life easy. The whole shebang is going into a 19.5" pine box with a old baldwin/leslie 12" alnico Jensen.

Missed you at the Mystic Garden Party, it was about 10 miles from my house but too much $$$ to get in there.

Peace, Erik

I don't know how to do a sketch in this format, I guess I would need a scanner, right?
But don't despair, it's exactly the old Mesa line out in a little box, speaker level in, volume pot, output at whatever, "instrument level" or whatever the input of the next device likes to see.

Here's a link to an old Boogie schematic showing the same circuit.

All the way over on the right hand side of the page. "Slave" it says. . .
That's all it is, two jacks, a pot and a resistor, I don't think the pot and resistor values are terribly critical within reason, you'll just hit your sweet spot at a different place in the pot's sweep.
You could probably get away with a barely cracked volume pedal with a little single-ended amp if you want to try it.
I have . . . didn't blow anything up!

Thanks Steve, that's just what I needed.
