The unit comes stock with silver metal tube covers or dampers. Did you leave these things on or take them off. If you took them off, what after market dampers did you use if any?
I took them off with know ill effects. The JD 100 didn't seem to have a major effect on the tubes as they tested new after years of use. (NOS Mullards instead of the stock) Never thought to use dampers.
Thanks for your responses so far. Since I have the addiction known as audiofoolism, i'm sure I will be rolling tubes soon. I was just wondering the advantage of the shields because they are one more thing to take off and put on.
