Re: OEI output transformer, EL34 or 5881? which has a better sound?

Peter S	Re: OEI output transformer, EL34 or 5881? which has a better sound? Hi Guys, I've used the Tesla 6L6GC and also Phillips 6L6WGB with the OEI OT. I biased them at about 50% max dissipation at idle. No problems encoutered. The transformer actually runs even cooler than it does with EL-34's because the 6L6's just won't draw as much current as an EL-34(given the same circuit). Both types of 6L6GC's perform perfectly well with the 3.4K load with no signs of stress. They sound a bit rounder, with a little more coloration at clean settings, but at full tilt the 6L6's don't lose as much high end as the EL-34s do. The 34's have when driven hard have a little more midrange honk and less high fizziness in the distortion sound. Peter
