I sent a note to Richard S requesting a schematic or just that part which shows the input circuitry.
Next step would be to open the case top and take a few measurements. See IF what I propose will FIT.
After that? If all goes well, I've got to RATIONALIZE about 200$ per amp in 'upgrades'.

That's a lot of money for a modification that might not sound any different than the stock potentiometer. Before I spent that kind of money, I would set the pots to the volume level you require. Then remove them and measure with an ohmmeter. Buy some quality resistors and install a cheap voltage divider. Leave one of your amplifiers stock and compare the sound quality.
My gut says it isn't worth $400 to modify two amplifiers but it might be worth installing simple voltage dividers. In other words, you might hear a slight difference but you might not be able to tell if it's better or worse, or just different. Moreover, even if you determine it to sound better, it might not sound enough better to justify spending $400. Of course, if it sounds significantly better and you want to install the stepped attenuators, then you've spend only a few extra dollars on the simple voltage dividers.
Good luck,

But…….But……But…..
It's ONLY money!
I might add, in all honesty, that the divider was the recommended 'fix' IF I could decide on a single setting. I was also told to expect 'some' improvement.
