I am glad to hear that I don’t have to write any new laws of physics :-)

I wasn't going to challenge you on the buttons you pushed on your scope George... :-) Don't worry, when things just don't make sense, check your setup.

Hi George Good, you narrowed it down...those 2 values really should not be sensitive, Their only function is to dump gain at DC to minimize offset.

You can DC couple them for testing to find out where your mod went wrong. Tack a jumper first across C21 (the 2.2uF cap), check results. Did it fix it?

that doesn't matter George, PL just increased the gain in the S2 compared to the S1. About 2:1

You sure you replaced the right ones George?

Especially when I stuff the box with used Christmas wrapping paper from the grandkids...

much better design work, PL really cheaped out and wanted to do everything in one quad op amp instead of adding a buffer stage earlier on to isolate the effects of the volume and balance controls.

Change C21 and C22 from 0.22uF to 2.2uF and you will notice a difference

Pretty much...

Increase the value of C42 and C43, go from 10uF to 100uF and you will notice a difference.

I will tell you George...let me look at the schem and get back to you

Agree fully. Gary wasn't it located there originally?

Gary do you really have the bridge rectifier mounted where it is in the picture? Not on the transformer?

I am awaiting delivery on a reorder of the base board, days away from having them back in stock. They sold out faster than I expected.

That is a great update Perry, you have been busy, as usual. I hear you about too little time...seems every year it gets worse. Us seniors are supposed to be dialing it back but it never seems that way.

Good to see you here Perry...

You forgot rule number 1. It's your test equipment...

None except that. If you plan to resell internationally, it may help you move it into that venue.
