If you have not installed the BeeQuiet, I would put that at the top of the list. And I would spend time maximizing isolation from mechanical vibration with lossy mass on the signal tube envelopes, lossy mass on the chassis, and squishy feet under the base.

I have done all that. I am running tongsul 6A3 and have the attenuator upgrade. I tried Mundorf coupling caps and now have clarity ones in.   I am waiting for a 6B4G adaptor and then I can try some of those tubes that I have laying around.   Do you find those to be less microphonic than the 6A3?

The Russian 6C4C's were the least microphonic that I found.  Using Dan's method of Herbies Tender Feet tall, double weight rings and dynamat extreme under the chassis  This this didn't due too much) was about as quite as I got it.  Those Russian tubes beat anything I tried for quiet tubes.  Look for a PM from me.
