The test with the SSHV2 regulator faild due to problems with current setpoint :? Next plan was to try CCS units as load for the 6sn7 driver tubes ( I have very good experience with the CCS work of Ale Moglia ) from Bartola valves Today I have tested one channel and ik looks great :mrgreen: hopefully...

I have the salas shunt regulator ( sshv2 ) in my parts bin

Yes AER MD1

Have listened for one hour and this amp has great potential :mrgreen: :mrgreen: All the capacitors are new so no tweaking till is set properly . With brass instruments it tend to sound a bit grainy, but hopefully it disappears. I have 6,8uf Obligato oil caps for bypass the output caps evt :roll: htt...

Today i did A test run for two ours on A 16-Ohm dummy load , no smoke or sparks
Did some tests with A squaire wave generator and set te feedback resistor at 3k for the moment.

Work in progress

Oke I have found A pair of Kemet /Rifa 6800uf 160vdc at a local dump shop for 8 euro a piece
Hopefully they sound as good as they look
If all goes wrong the speakers should be safe !

I have one channel up and running :D for testing. https://www.mupload.nl/img/vydwhl.jpg The 6c33c is set at 387ma with 3,3ohm set R ,grid -34 and anode supply 155,5v . In a couple of days I hope to build the stereo version on a piece of chipboard. The only thing that scares me are the delicate 16 oh...

Good news

Nice boards !
Almost ready for a one channel test build

Hello Ray, I am definately going to build this amp, maybe the 6C8G instead of the 6SN7 but listening would decide that. For the driver stage I will use the SSHV2 regulator ( diyaudio ) I could not find powersupply details, but it also looks a bit like the Mini Beast power supply. Probably I will sta...

I like this project very much :D I have the Oris 150 horns with 16 ohm AER drivers that must be a good match. From earlier OTL projects ( Tim Mellow ) and the Trancended Mini Beast are a lot of parts at hand , as tubes and sockets and transformers. Would you share your powersupply design :?: Grtz......
