Re: 25 watt EL34 JCM 800 build

For the record, the ctone 2202 is a 6v6 based 2204. It both sounds and feels like some of the best 2204s I've played through, and much better than the 2204 builds I've played with 34s and low Vp to drop the power to 25 watts. Point there is: do not be afraid to build low watt marshall style amps wit...

Oh well, to be fair it usually brings granitic minds to create walls and start flaming. It is not my ...

Re: coupling caps in tonestack... inaudible??

Some producers (EG Engl) uses a cap before the tone stack to avoid DC on tone caps, and without that cap the sound is indeed different. I've experimented with 1uf caps before the tone caps and could hear no difference. I have pretty sensitive ears. Some brands like diesel use a .22uf in the same sp...
