Hi all,
I'm new in here but fall in love with music for more than 10 years, already using some of system and visited lot of hi-end systems in my country, but what I really missed when listen is Giant tube amp.
Before of it, i owned many other tube amps, and also listened lot of configuration, but what the giant tube amp like 212 or 833-A strongly motivated me to build one. and now I just finished pair of power amp, and it really make me exciting when ever I turn it on. any one have the same hoppy?

All the cuts in the cones remind me of the “West Side Story” sound track.
 
Great looking amps!
A friend and I worked with a builder in Vietnam who is expert and winding transformers and chokes. We worked with a with him to design and builds amps around tubes we are interested. All and monoblocks and most a SET.
Last year we built a pair using rare Philips TB3-1000 tubes which are a variant of the 833 tubes.
The amp can also run 833 tubes with some minor modification to voltage (moving a couple internal wires) and changing out the tube sockets as the Philips are slightly smaller.
The amps play very well and while they don’t quite match the finesse of the 211 and DET25 amps we have built they will work very well with a wider variety of speakers where their 100 watts is an advantage.
In this picture they are driving the bass in my DIY speakers. AER BD3 running full range with a Supravox 285EXC fieldcoil covering 45-160hz and a SWARM distributed array sub system for 20-45hz.
The amps in the back are driving the AER and they are E55L driving 211 where the E55L is rectified by a Tele RGN 2004 and the 211 is rectified by 4-gz34. So they are fully tube rectified with choke loaded power supplies and no capacitors or resistors in the signal path

The green box is a linestage we also built using Marconi U8 driving Telefunken AD1…kit is
Minimalist with no remote but sounds nice.
