Hi JJ, I am not going to hang on to this amp as I have too many el84 amps. I just wanted to get it running properly. The fix to the fb seems to be good as I have no oscillation and the sound is decent. About the coupling caps I did upgrade them some. I went with .006 and .06 uf for each side. I think after playing the amp for about 4 hours that the bass is a little better. The sound is nice and lively with lots of sparkle. I upgraded the power supply with a CLCLC configuration which dropped the B+ down to 330 vdc with a 5u4 and 360vdc with a 5ar4. cheers, Dak
