Paul, just rewired as per your diagram. Your green is my blue. Busy schedule for the next couple of days. Will try to test during the weekend. Again, keep your fingers crossed. Thanks for the help.

PB, Help. Started testing and before I knew it, no signal. Thought it might be a tube and as I was pulling one out to replace, realized that as the top plate was flexing, I had a signal. Since it's both channels, do you have a thought as to where I should start with the chopstick?

Visually inspect all solder joints. If you don't find the bad one, do all voltage measurements.

Doc, Thanks for the guidance. Found that the 6" STP red wire where it is attached to T6U had broken. Repaired and resoldered. Did the resistance checks for that terminal and all the voltage checks. Back to sounding great. Will test the switch box in a couple of days. Btw, I found during the original build and now that the wires in the STP are very brittle, one little nick and they'll break. Think it would be good to amend the Eros manual with a warning to future builders.

Doc has a sticky post on wire strippers in the tech tools board where he recommends automatic wire strippers. Broken nicked wires are a common problem that the Bottlehead crew deals with all the time. Finding a break under the insulation is very hard too. Bottlehead support is awesome!
