Hey guys, I just recently joined DIY audio and I've been scouring the web searching for a way to calculate the proper transformer for this project and can't seem to find one. Anyone mind giving a new guy a hand?

Can anyone please chime me in on the use of the JLH power supply pcb?

Why can't I order to Lithuania? Latvia is there, but Lithuania is not.

Default JLH amps

Hi SiliconRay.

I have just placed two more orders for the JLH amps and PSU. Got the first lot from you, and should have requested first batch with 2n3055. Reason being I'm going to be using MJ802 transistors in any case.

Help me with something else please; I have very little electronics knowledge - I can assemble and do basic trouble shooting - but how does one test to match the output transistors. I have about 40 MJ802s so have a whole bash to choose from.

Thanks, Kevin.

BTW great website - I'll get around to a tube SE amp one day. Will post pics of JLH amps when done.
