DHT (directly heated triode) preamps - who makes them?

The WBA Blazebird pre uses 2A3 tubes

I think that these are not DHT preamps but my GAT2 and more importantly, my Misho Wooden preamp are just outstanding. I especially love my Misho preamp and if I had to pick only one, this would be it. No nonsense and solid design. Sounds beautiful with the quietness, depth and layering of the best and super reasonably priced especially compared to my GAT2. Tube life up to 10K hours - holy cow how can you beat that?

malvern audio research are getting into making these with Ming da

Following the successful launch of the 211 Mono blocks, Mark is now working on a matching DHT(Directly Heated Triode) Pre- amplifier to compliment them. His aim from the very begining has always been to design artisan valve based products for the 21st century.

Hi Phil, I compared his power amp with thoress hybrids and silvercore 833c on the horns Universum. His was better. His then preamp for 2k was better than the thoress even with the thoress power amp. His new one with 101d I am really looking forward to hear.

We also compared various 211 valves in his amp. KR, Psvane, RCA, GE, and Amperex. The amperex just killed everything else but they are too rare and impossible to get.
