Need schematic for a 20W bass amp | diyAudio
https://www.diyaudio.com/community/threads/need-schematic-for-a-20w-bass-amp.213063/
I saw loads of schematics for 18-20W guitar amplifiers using two EL84 tubes, but I can't find any schematics for a bass guitar amp. I have most of the necessary parts, so I'm looking for an amp schematic that uses two EL84s to produce about 20W.
