Tweakie,
Synrad was talking 2500 IF they could do it. I am just hoping to find something better than that. I'm not using it much and have a friend who has a 50watt at his shop who has handled the "have-to" work for me. I just like having it available.

SkipW,
It looks like they are about 1/2 the price of Synrad. Well worth the investment. One guy quotes 1000 for them recharging his tube which, while a lot of money, is much better than 2000-2500. Thanks for the point.
