Re: Audible Differences: EL34 vs 6550 - yeah just a little!

216.237.57.66

Here's a link to Mr. Spafford's discourse on the benefit of proper bias on EL34s to handle the bias debate. (see link below)

The sonics you will achieve will depend to a great extend upon WHICH brand(s) you choose to try in your Jolida. What brand 6550 are you using now? I have a Jolida 302a (same circuit, chassis, etc. just a different set of resistors). In my amp, I get a HUGE change just going from Svetlanas to EH (EL34), and therefore I prefer one brand over the other in a big way. I would expect you to have similar results.

Since you state that you're familiar with the difference of EL34 vs. 6550, then what are you looking for with regard to an answer? I'm not challenging you here; you obviously know what you're doing already. Just wondering anyhow.
