- HiFi Trade?
Could 6CA7s be used in place of EL34s in any amp or could some amps not like them? Specifically a unison research S6.
Hah! Stupid thing is designed to try to kill you while biasing. :xMy Air Tight is labelled for 6AC7, but it's always had EL34s in it. Actually it now has E34L, whatever difference that makes.(I just stick any old tubes in, then Pete swears at for a bit while biasing it because the twiddle pot is hidden behind the high-tension electrocuter, or some such. :dunno: )
Funny, I prefer the EL34's in my quintet over the 6CA7's, this says a lot for both personal tastes and synergy with the rest of the system.I put a quad set of 6CA7s in my Art Quintet recently. A definite improvement over the EL34s.
That's the Wam for yaSo far we have: It's better, it's worse and it's different. :rofl:
Good point. I probably should have said "functionally identical." Lots of Phillips and Mullard EL34s wound up in the US with Fisher, Dynaco and Realistic labels and 6CA7 numbering on them. I once had a pair of Mullard xf2 branded Realistic (Radio Shack's house brand) and labelled 6CA7.Not quite true, the original 6CA7 is a beam tetrode, designed to get around Philips' pentode patent while the EL34 is a true pentode. Electrically, they're interchangeable, however. Wouldn't surprise me if some modern production variants are the same thing with different labels, however.
