It's not a hybrid, in fact it's all tubes and it's not for the feint of heart or wallet.

Anyone who wants to see or listen to it should swing by CanJam table 13. I'll be publishing the design when I get back and can polish the documents.
Are you talkin' 'bout this?

Nope, that's a commercial design, the one I'm talking about is DIY.

Just to be a wicked tease, here are a couple pictures of the project I lovingly call, The Menace.

The Power Supply (~50lbs of tube rectified goodness)


The Amplification Section (6SN7 input, [2] 6AS7/6080/5998/7236/6528 output)


I fired it up for the first time two nights ago, redid a bunch of the ground wiring last night and got about an hour with it before packing it up and shipping it to Florida this morning.

Wicked tease? I have another name for you, but it would likely get covered in asterisks!

It's a beauty, Nate. Very high drool factor in so many ways. I'm sorry I won't be able to hear it first hand.

Guess I'll just...get back to...being a Starving Student!

Pete, I'm sticking to the starving theme as much as possible. I need to order some caps from Handmade and Soniccraft for another project, but I promise not to drop more than a dollar or so towards caps for the SS! (Handmade does have a closeout page so I'll have to dig through it for SS-worthy components.)

I'll do that this weekend at some point and sketch out the basic details. I have schematics but I'd like to polish them up a bit before releasing them to the public.

I refuse to keep track of things like that, lest my wife some day discover how much this stuff actually costs! Also, there's no reason that you'd have to use the power supply design that I did, you could save an awful lot of $$ doing a SS power supply. And I had a specific goal when I started this project that precluded using anything solid state.

Guys, there are still a ton of these power supplies on Ebay. Try searching using the string "34-1977" which is a part of the part number and I'd bet you'll come up with a whole host of inexpensive options.
