The second work

Two monophonic scheme williamson modified by H. heroes, these amplifiers love ascoltardi with KT90. At the center is a preamplifier based on the scheme "lillipre" of Megahertz modified in power, I preferred to use a 5U4GB instead of bridge

My 6AS7-6080 OTL Headphone, SE amplifier. Delicious sound.

Experimental stadium: Two stage Single Ended with Psvane WE275a replica and 7788 driver.
Compact build, all filaments AC. As silent as can be with ~2mV residual hum from WE275a.
All transformers Dutch made..

They appear to be from Martin Mug.

Yes Bas, you are correct.
Power transformers are by Peter Vlaar(tronic).

Can you tell us more also about your speakers cables? They seem quite original (WE wires?).
Maybe in another thread (OT?)
Thank you!

Those are not WE but homecooked. Gilded solid copper, cotton isolated, 9 wires per conductor..

very very pretty build DHT2009. wow I would like to sit and look at the unit from the bottom all day long, while listening to music through it of course too ;-)
I would make a rack to place the unit upside down...lol
