Coronado 575 Volume Control Issue

[Winky Dink]

Yes. It was easy to replace the grommets.

Turning to electronics,

Previous suggestion:
"I would break the connection between the plate of the 57 and the 1 meg pot and insert a capacitor there, to take the pot out of the DC path. Likely a .05 would be ok in that location...I would also try a larger value for C-9 for a more mellow tone...”

My reply:
Replacing C9 with .01uF did improve the tone, and replacing R9 with 100Kohms restored the original plate voltage. I also tried putting a cap between the plate and the volume pot, but that seemed to have no effect except to lower the sound level. At this point, the audio is satisfactory.

A subsequent suggestion:
"The way you had the volume pot connected was semi-correct. You need to use a cap .02 to .05mfd between the plate of the 1st amp tube and the high end of the volume control. The wiper would go to C7 and the low end to ground, as you had it. It should correct your distortion problem."

Is this the same as the previous suggestion? The blue is how I wired it before, but noted no improvement and removed the capacitor. So I humbly ask if there is something "semi-INCORRECT" in this picture?"
