Tom, Thanks for your comments on topic... Well it is a "range" and I did ask the question had anyone done testing. Apparently none of the people on this list have ever done the tests and these figure

Just swapping sidebands will not take you out where you need to be to look for the IM products. You need to be looking out about 4.5 KHz. Rich, Tom and others discussed the measurement of IMD in a pr

I use switchers for the filament of the GS-35B and GI-7B which both have indirectly heated cathodes with no ill effects at all. Be sure to use a separate cathode choke for the B- and the bifilar chok

That makes sense and it really isn't an issue of peak versus average to me but rather a means to compare the levels Ok... in my case I use the old TS-940 and I would have to put a generator on it to

<snip> Gary, I think if you re-examine this, you will find that the products you computed fall on both sides of the carrier frequency. Switching sidebands does not move you to the very next channel.

Gary, Perhaps that is where the confusion is/was all along. My point was that, as you pointed out, there is a very large portion of the IM that will yield mix frequencies outside the normal listening

My use of the words "average IMD" was out of place and I apologize. Please do not let this cloud the discussion. 73, Tony W4ZT _______________________________________________ Amps mailing list Amps@c

Bill and the group, The information regarding power dissipation I put on that page didn't come from any published data sheet but rather from empirical knowledge gained by those using the tube. Rememb

I'm getting tired of this endless attacking and name calling. Obviously Rich's suppressors work. Some just can't seem to admit that part and want to argue the technical differences in what they COULD

W4EMF, K4POZ and others frequently put an air box around the tubes to insure the air flows fully around the tubes and exits above the coolers. I have more pictures of them at <http://gi7b.gs35b.com>.
