i'm planing to build this tube cake with non SMD component,
but can i change j177 jfet's with bipolar transistor like bc 557 ?
and what is the replacement for the bcp 56 ? maybe bd139 can do it?
any recomendation?
sorry for the silly question

Sorry m8 i don't know about repalcements i will use SMD transisotrs. mmbfj177 and bcp56-16 it's not problem to get them in here...

sound ok but i recomend you to build biger PA.
The one that J0K3RX post is good to, but you can't connect it to ground only the parton input rest same as speeker ground going to jack and it have easy to get parts. You must use transformer on about 30V to have 10W if you use something about 36V you will have about 20W from this power amp. It have realy good dynamics and "sound" good...
