Greetings: I have been recently been able to look at a Rhode and Swartz 5 KW solid state UHF TV Transmitter, water cooled. It sure works and works very very well. It is all in a single 19 inch rack,

Very tricky, unless the operating conditions are chosen to keep the device within survival limits either all the time, or at least long enough for protection to kick in. More often than not, the ulti

There is a very "cheap" solutions for the problem... not terribly elegant, but it works great in my Harris 3230... fuses and transorbs. The FB fuses solve the current spikes, and the transorbs (acros

A genuine question, not a sniping comment - has anyone looked at the frequency range where Tranzorbs work in this situation, and/or measured their impedance vs frequency? Steve ______________________

** Good question, Steve. There could be a problem with junction-C on higher-Joule transient-V suppressors for RF service. _______________________________________________ Amps mailing list Amps@conte

There can be major cost advantages to building tube amplifiers - it's easier to beg parts, as GW4DGU well knows - he gave me a vacuum variable and a 4CX1000! I still feel that a 4 tube 4CX250 HF amp
