I'm using Hal-O dampers on my NOS Amperex 7308's in my Herron VTSP-2 preamp. They made a subtle improvement with these tubes, and also with the slightly fatter stock Electro-Harmonix 6922's. I have the top-of-line "PEEK" black ringed dampers.
Tube Dampers on the Herron phono preamp?
Will using tube dampers (I'm considering Herbies Halo dampers) on the miniature 12ax7 tubes inside a Herron VTPH phono preamp make a sonic improvement? Because the 12ax7 tubes are so small I'm skeptical about wheather there will be any difference using these dampers. Thanks
