Based on this (shishido - attached) with some variations
The OPTs with one word are fabulous. Especially in low frequencies I have no words to say!

No affiliation or anything.....but Monolith is one of the best EVER opt's.The cores,copper and windings.
Tribute Audio probabily second and Tamura/Tango/Lundahl/Bartolucci/Hashimoto/Sowter in this order came up.....
...my oppinion of course.

What speakers do you drive with this 2A3 amp??

my monoblocks are gathering dust .

Meanwhile i'we been busy with horns .

I need to build a few more parts for the amps, like transformer covers and spikes. A few more 100$.

For the speakers...i still need a ton of money and some patients.

Meanwhile i will enjoy the dynamics of this ogly prototype, thinking about how good my future speakers will sound with SET amps.
