All fixed! Amp sounds great again.
I replaced the anode caps with ceramic versions.
Replaced 8 EL-509 power tubes with tubes from my "NOS" cache.
Then I decided to take a look on the component side of the board and found 4 leaky 1 mfd 630v caps, so replaced those.
After all above replacements, still not much improvement. Sound was thin and distorted in the lower frequencies.
As a last resort, I decided to check the fuses. The T8-LN has a 1.5 amp fuse for each channel, and a 6 amp power fuse.
Since I always had sound from both channels I never thought to check for an open fuse.
But one of the channel fuses was open. After replacing that fuse, all is good!
