Don't know. Thinking about bare, anodized. With or wothout the 700 badge in the middle. Depends on how many are still good...

After Timdalf's noise measurements, unless specifically asked for no pots, no direct/normal coupling switch, just on/off and meter attenuation......

That makes sense as most will use a preamp for volume control and you can ditch the other toggle switch - that should help with the self induced noise.

Did you see the latest noise figures?? SNR was killer too...
That was in Timdalf's WOPL thread I'd guess. A couple hundred microvolts across the band - that's not much for those that don't know. Those are amazing numbers for a 40 year old amplifier. Amazing for a new one too. Fantastico!

Yep, weighted was 89, and 83,,,jeez...
It is amazing what a good design, good grounding technics and proper wire routing will do - along with other upgrades. You and Joe have been at this for some time and it's cool to see the results. Great job guys.

I gotta agree, lots of progress has been made, some painfully (for certain components, poor Pig)
