Interesting stuff again.
I ran the Westy 6V6s and went to a lot of trouble to check output.
The "westy" looks very much like a 7591, so the large anodes.
Basically anything over 7-7.5V output into 10 ohms and the amp starts to clip...
That's not much more 5.5-6W REAL...in FIXED bias already better than Cathode bias.
Far far away of course from the claimed output of 12W RMS.
I also measured IMD and as expected, no matter the output level, the 6V6 is pretty much a dirty horror story.
I started to install the "EBL" Pentodes in loctal sockets now and hopefully we get rid of IMD and have much lower THD.
I will post the results here.
