Thank you for the reply and ideas. I appreciate it and they are a great help.
I'll have to open the amp again and see if I changed out the 220k's. It's been years. If not I'll try that. I'll also see what's installed cap wise. I believe stock that the Bandmaster TFL5005D had a 5uf. I may have went to 10uf but probably not 25uf.

K40Y-9 take 50 hours to sound good and 200 hours to fully break in.
220K on the power tube grids does not change the sonic signature. It keeps the power tubes from running away.
I'd had some 5mfd/50VDC caps a long, long time ago. Used 10mfd/50VDC and even 25mfd/50VDC. No difference in the tremolo tone, that I can tell.
An 8mfd/150VDC Sprague ATOM will fit, in that position. AES now stocks 5mfd/50VDC ATOMs.
I wonder if I have the wrong tube in the spot. I'll have to check on it.
I am not sure I would go with 6U8 or 12DW7 phase splitters. Any 12AU7 as in 1/2 of the 12DW7 are not good sounding tubes. I know a phase splitter is not as critical as preamp circuits, but every tube counts. 6U8s are ok, but still not an audio tube.
The best 12DW7 by a long shot were CBS 12DW7s. They are very rare now. It may take over a year just for one to show up on ebay.
