[QUOTE="Ampdog, post: 219966, member: 144"] To chime in, I have never heard of the ECC807 and looked it up. A ?=130 at <2mA for a triode! The construction had to be pretty sturdy to keep that from being microphonic. The closest to my knowledge is the ECC83 with a ? = some 80 as normally used in pre-amplifiers. Also nothing to recommend, except a circuit change (not only valve connections, also component values). [/QUOTE]
