6V6 in triode connect mode - Page 2

gingertube · 2nd May 2005, 05:03 AM

No reason why you can't use UL for 6V6 - Va max 315V and Vg2 max 285V - I'd say its damn near ideal.

There is a fellow here in OZ whose been designing and building his own tube amps for 30+ years. He claims his favourite amp is 8 off 6V6 UL connected per channel (4 pairs). On my estimates he probably gets about 40 Watts.

I'm a big UL fan - check out IM distortion figures for Triode, UL, Pentode of just about any output pentode data sheet and guess which is best - UL everytime. This is telling me that UL is the most linear mode to run a Pentode. Also easier to drive than Triode Mode (low input capacitance).

Cheers,
Ian

The 6V6 predated Hafler/Keroes.
