Guess what I'm building....

[Tig***]

Wow, that looks top notch!

[Commodore 64***]

It really does. Very nice. I'm amazed how fast it went together (once you got started ).

[bcdon***]

Well done. That looks so nice. What I find so amazing is that such a simple circuit made from discrete components can do so much and produce such art. Bravo!

What kind of speaker cab are you planning on running it into?

I have a Drive ported 2x12 cabinet that I loaded with an Eminence Red Coat Wizard and a WGS Green Beret (Greenback clone). The cab has a definite British edge to it, so should match up well.

Beautiful, clean work you did there, DVM! Congrats on completing the project!

[Blaze]

Wow !! that's a beauty ..You finaly did it DVM.. Great job as usual ..I m sure you will love it ..

Congrats ..

Obviously an audio Clip is a must !!

[Monkus]

Looks flawless DVM, great job....clips?

[deeaa*]

Pro Work dude!

Last couple of photos--mounted in the head cabinet, which I also bought from Trinity. Was in a blond mood that day:

I think the question that is on everyone's mind is: Will it give me screaming solos?

This amph will most definitely give you screaming solos. Particularly on the high input to the TMB channel, with the gain cranked up around 8.

I will try to post a clip. Hopefully, it will take me somewhat less time to do so than it did to get started on this amp....er, amph.

Considering the length of the build time, could this now technically qualify as a "vintage" amp . . . ??

Seriously nice build there, DVM - just as I'd expect. Cheers.

Well, DVM himself qualifies as "vintage" so . . . *ducks*

Good to hear from you again, Nelskie!

To both comments, I respond with the words of former Vice-President Spiro T. Agnew: "Nolo contendere"

Good to see you here, Jon!

Absolutely stunning!

If you don't mind me asking what tubes did you use. The recommended " The Tube Store" on the Trinity Web site is just down the road from me. I have bought several tubes from the. I am one of the few people who have used there walk up sales desk.

The EZ81 rectifier came from our own Tunghaichuan (tip-o-the-hat....a very generous guy!), but the rest are JJ's from Eurotubes.com. Bob & the gang do a great job over there--super service and excellent pricing. And I've had good luck with JJ tubes.

Sweet build DVM

UPDATE 2/29/12:

To tame the output volume while maintaining the nice Marshall crunch, I bought a voltage reduction module (VRM) kit from Trinity Amps and installed it. These units install on the DC rail of the amp and let you drop the DC voltage while the AC filament heater voltage remains unaffected. They have the reputation of doing a great job of reducing the output volume without a significant amount of tone loss, which is a common complaint with external attenuators. For a cathode-biased amp like this 18W, it's a very straightforward installation, and it works exactly as advertised. I can dial down the DC voltage enough to run the preamp gain up all the way and the master volume high enough to get some nice power tube saturation, and still keep the volume to a non-lethal level! Pretty slick little modification!

Couple of photos below. The VRM consists of a MOSFET mounted against the chassis (with an insulator pad in between) to facilitate heat dissipation, a small PCB with a handful of components, and a 1M pot to control the DC voltage output. It's wired in between the standby switch and the first filter cap, and I have the control pot mounted through the back of the chassis, between the mains connector and the output impedance selector switch. The Trinity kit also came with a couple of DC blocking caps for the inputs to the first preamp tube, in case you find that the volume pot(s) on your guitar pick up some scratchiness. This can happen due to a very small amount of low voltage DC current getting back to the guitar controls through the input jacks when the voltage is cranked way down, but I haven't had to install those on mine.
