Thoughts on Audio Research D70
Yes. I was thinking it was a D-70. D-115 will get you 60Wrms..

My mistake, that should read ECC83/803S 
CJ PV-14L replacement tubes
What is the tube compliment for that unit? 
Thoughts on Audio Research D70
You realize you will only get about 35-40Wrms across 8 ohms in triode configuration...

My guess is it's not quiet enough

sorry that should of read JJ ECC803S

Try the JJ 12AX7's or the 603's are even better.... 
Anyone compared 6922 Sovtek & Electro-Harmonix
Yes, that's an issue as well. As long as there not way off they should work just fine depending of course on the circuit. Honestly, there just isn't a really great 6922 on the market. If you can find inexpensive legit Amperex 7308's that's my favo... 
Anyone compared 6922 Sovtek & Electro-Harmonix
I stopped using the Sovtek 6922 at the same time ARC did. They are just too inconsistent. I would measure one and it would measure great, measure the next Sovtek and it measured poor. The EH's are a more consistent and don't measure weak after a f... 
Audio Research LS-9
I believe what you are seeing, are the chips for the logic circuitry/ volume control. From the pics it looks discrete.

Bypass with the same manufacturers caps as the coupling caps.. 
MC240 vs 8B
I've had experiences fixing both the MC240 and the 8B. I love them both however my heart belongs to the 8B. A more simple circuit then the MC240. BTW Bob is a great guy. The 240 has more stages of gain and more coupling caps. The original bumble b... 
Did I blow my tube amp?
Normally, when I bias a tube amp, unless the manufacturer says to have a load on the output, I don't. I do however, have shorting plugs for the single ended inputs. That way I know there is no signal going through the amp while I am biasing it and...

These caps are huge and made by the company that makes them for ARC.

I have some 1mfd@600V teflon caps if you are interested...
