The RCA Inputs should not be touching the chassis in any way. The RCA Inputs (signal and shield, or center and outer, or hot and common; regardless of what you call them) should only be connected directly to the control Board. The Right and Left Channel input common wires (usually Black) are...

I have Gmail on my phone. I never logged off of my email on that device. That is part of why this is so maddening!!!

Are there any Gmail technicians out there??? I created a .biz account in Gmail just for fun. When I saw the monthly cost $21.60), I decided not to go forward with their "Recommended Plan" but there is no exit from that Google Workspace Accounts page. This one...

How about a Frequency Response test using the same configurations?

Horns are wonderfully different animals.

The White Oak Audio Model ONE Amplifier is compete! The delay was caused by not having two specific #10 16-14 AWG PIDG terminals for the Speaker Output Binding Post connections inside the amplifier. I received them from Mouser on Wednesday. I have just started the 53-step Bring Up Instructions...

You want bling? http://tinyurl.com/494bthvf Is the Acurus RL11 as good as the L10? Better?

Even the fully modified PL2000 Series II with OPA2134 OPAMPs?
