Looks nice for load lines in triode connection, but I can't foretell, you should sort out some good bias point and try in the same general config I guess. Does not look like getting 5W as easy as the 6V6 bottle in this one, but it could be better for acoustic feedback due to smaller bottle? Maybe. Run it conservatively. Note the 250V plate limit also.

Ok thanks. If it doesn't sound that great, I'll go back to plan A, which was an SRPP or mu follower. I just like the simplicity of your design.

Look at the performance of the amp. He has it listed somewhere how trioded 6v6 performs. You really should try it. Very impressive

Sounds very natural the amp using 6V6 as final stage.

Hi all,

I've been using 6v6 linestage now for more than 2 years without any problems. I'm still in love with it and would not part with it. Thank you very much salas!

My friend heard the preamp in his system and would like me to build him one, so we got the power transformer and choke for the project. Trouble is I do not know how to use psud to get the optimum performance from the power supply. ( (I really do not know how to use the psud)

I need help on designing a proper power supply, Please help!

Hammond 272hx power transformer
Hammond 193j
5r4gb rectifier, type 83 mercury rectifier,
4.7 if oil cap
470uf caps


Any input is greatly appreciated. Thank you

Ivar

Hi salas,

I can get one 5u4gb no problem. If I use it can I just follow your power supply scheme?
