Oh

I've just registered to this forum... oh my... what a nice place for DIY fanatics... !

I'm working on a class-A SE 8 Watt/channel with 2A3 triodes and toroid style power/output transformers. Pictures will be available soon..

After this the preamp will follow.. everything will be ready around may 2004.

Nice job guys!

Default 6BX7 Williamson

Well, this has been my main amp for a few years. I know it doesn't look as neat as some of the very beautiful creations I've seen here, but I guess that is because it was a "work in progress" on a recycled PA chassis that became permanent, so to speak.
Anyway it is an all triode Williamson-ish topology, currently with 5687 as concertina input/splitter, E182CC diff. driver and 6BX7 with both sections parallelled as output tubes. The OPTs are from Revox tape recorders, originally teamed up with ECL86 tubes. Power out is around 6-7W if I remember correctly (it's a couple of years since I built it) into my stack of Large Advents and Electrovoice speakers... yeah I'm a vintage geek I know

Default A Better shot of my DC coupled OTL

Here's a better shot of my stereo DC coupled OTL amplifier (in the fireplace). Besides the 6AS7G's, you can see four large can computer 'lytics that form part of the output stage supply filters, and several oil filled polypropylenes that filter the input and driver stage supplies, plus a 700VA toroid kit that I wound the secondaries on which provides the output stage rails and filament supply. The input and driver stage supply transformers are mounted under the main chassis plate along with the filter chokes. The input stages for both channels are hidden behind the big 'lytics in this photo.
