A lot of really nice-looking hardware!
Here's one of my 300B monoblocks. All vacuum tube with no solid state components.
A nice "classic/classy/compact" look, multibiker : is it a kit or you have designed and built (or have it built) the sheetmetal work ?
It reminds me one of my 1st experiment with the 300B : 12AX7 + 5992 (kind of 6V6GTA) + 300B.
A+!
My 6aq5, my first completed amp.
Nomanland,
This is a very compact SE circuit, indeed... And a good start !
You do not notice magnetic induction between the cores of your power transformer and output transformers ?
A+!
My most compact so far. QQE03/12 push pull, 2 x 10 W.

Here is mine, a pair of Fred Nechbaur's 13em7 Minibloc amps built on a 6x10" Hammod chassis box. I built these as a fun system, I also built a pair of Fostex FE103En bass reflex speakers and for the source I am using an unmodified Playstation 1 as a CD player. It sounds quite nice for a modest amount of money.

cheers mate, there is a slight hum but only when you have your ear right up to the speakers.
For a stereo 300B, I'd consider my Damn Good 300B to be rather compact.
28x38x8 cm, 17.3 kg. Classic-Tone power transformer, Electra-Print output transformers. Shown below with 6N6P driver tube, though, I'm currently using JJ E88CC drivers.

Thanks for your kind words. It's my own design, my first tube amps in something like 40 years! I documented the design and build process at www.ampwerks.ca.
Thank you. Here's a bottom view.

Yep. That's exactly what I did. I drilled three holes through the top plate and into a plywood block at the extremes of the grid. Then I drove a brass pin into each of the three holes through the perf plate template, anchoring the aluminum to the plywood. From there, it was drill-baby-drill...
Once I had the jig figured out, it only took about 45 minutes on the drill press to make the vent holes.~Tom
This is 22 cm x 19 cm x 5 cm (without transformer case).

EZ10 6V6
Here are a couple of the mini-monoblocks I made with a pair of 6V6's and an 6SL7. Based a bit on an old Slivertone model that used a 7025 as the input stage. The amps are build on a small 6x10 hammond chassis.
I use these every day on my computer for sound and really enjoy them.
