That's a valid concern... Get yourself a GS-35B and build a good legal limit amp with a $100 tube that glows in the dark! 73, Tony W4ZT _______________________________________________ Amps mailing li

That's right where it should be. With only 13dB of gain vs the 8877's 15dB of gain, that's right on target. It takes a little more drive but most folks have more drive today than they know what to do

Better be prepared to pay lots... I was also looking for one but finally decided to build one after seeing power supplies go for more than the RF deck in a couple of situations. 73, Tony W4ZT _______

I used a transformer almost identical to this one in my GS-35B tube tester <http://tester.gs35b.com>. It has the welds nicely done connecting all the lams together. Even after driving the shunts out

I see no problem using a pair of them. In fact, it makes it easier if you want to run a full wave center tapped HV supply. I would still pull the grounded end off the ground lug and bring the junctio

My experience with the MOT is that it does not deliver a constant voltage. In fact, quite the opposite. There is quite a bit of voltage drop with load in the supply I built. I agree with the earlier

Will, Do you think that the welded laminations will not be a problem and increase losses? Beyond that, what you're saying is good news. 73, Tony W4ZT _______________________________________________ A

John, The MOT I used in my tester (<http://tester.gs35b.com>) has welds across the laminations in four different locations. The transformer gets pretty hot with no load (shunts removed). Fortunately,

Kevin, I have experienced failure of PVC used as a chimney. This failure was NOT due to temperature. See <http://gs35b.com/pvc/>. Though this may be a rare occurence it is certainly worth considering

Pat, Although the GS-35B doesn't really need a socket as we know them, it is best cooled using a mounting fixture that assures a good flow of air around the filament, cathode and grid connections as
