Tube dampeners on ARC gear ... FREE TWEAK

"you will get better dynamics, bass, mids, highs and a lower noise floor. Try it ... you'll like it. "

Are you sure that you didn't just get a good shock when you were fooling around with your amp?

Something I didn't know, thanks for the info.

On the stock tubes from ARC with dampers, they are placed high up on the tube but not fully on the silver upper end of the tube. Are there any gains to be had by moving them up, say, the distance of 1 1/2 damper widths so that they sit beyond the translucent part of the tube as opposed to beyond the plate structure?

For better tube damping, try the ones by Herbie.

I also previously found that moving the rings to the uppermost top of each 6H30 to be the best position, and have also removed the rings from the power supply tubes (I have Ref 40 which utilizes 10 6H30 tubes, two of which are in the power supply, one for each channel). I tried herbies tube dampers as well, but the rings were better sounding in my system. I also found that two rings as supplied by ARC were better sounding than a single ring on the tubes in my system.
