Pleasantly surprised - amp modification
I did a quick and "dirty" rework of my RH84SE EL84 SE amp.
It was always an amazingly good little thing.
But.....
It had a habit of going unstable which I eventually suspected was due to the CCS on the EL84 cathodes. Theoretically a good idea. Mostly it worked. But I'd get motorboating or sulks.
So I opened out the valve bases for octals.
Rewired it with 270R on the c athode from the 6V6 data sheet. 250V on the anode. and plugged in a pair of 6V6.
bunged it all back in a very good stereo system
and wow! unless I want metallica volume it sounds reet nice.
Just a thought, small room sensitive speakers, a couple of watts and audio nirvana. innit?
