Default Show us you COMPACT tube amps !

Hello Tube Audio Diyers All,

I like to realize tube amp projects which are compact-sized...

Compactness doesn't necessarily mean little performances !

Compactness often goes with nice design, aesthetical vertues...

I am indeed not the only one to like compact tube amps, and some of you have probably built several ones - Please show us your releases, and comment it...

As an example, I start the first :

Here are my "compact" 6L6 ultralinear mono blocks (only 10Wrms no NFB loop low power class A operation) :

Here's a mock-up of the 6BM8 spud I'm hoping to get around to building any day now... guess that doesn't really count, does it?

Sorry; it already belongs to my brother in law...

But I can build for you something like this one:

However, it does not looks compact from outside, but inside it is pretty tight: it contains SS stabilizers for preamp, for screen grids, for bias, and preamp filaments.

Here's a bitty spud - my "Mighty Mite" amp. It uses the 6LR8 vertical deflection tube, Hammond 125CSE output iron, and a SMPS inside the box. Right now, the thing is set up with the output pentodes in triode mode, but I may change it around to "Schade style" partial feedback to coax some more power out.
