Re: RF Output matching using attenuators

For tube FM transmitters I was fond of loading input tanks with power resistors to use up surplus drive power. Directly reducing the Q at the grids would improve fidelity and stability. No downside really. I operated a pair of 4-400A's in push-pull at 100MHz (data sheet says 60) with ...

Hello from Minnesota....
OK, I got hooked by the amazing Video amp posting and with no day job for now I have time to post once in a while.
I'm hooked on stealth solar and LED lighting as well.

Re: Video output transformer design
5) You did say 'sweep' the frequency? Would you believe a large (Tesla coil sized) Variometer with a nice long plastic rod to the rotating part? A simple p-p oscillator using those 3-500Z's could drive the thing. Fire it up and twiddle the knob. A frequency counter with the cap off the input jack ...

Re: Video output transformer design
The tomatoes are going gangbusters so I'll briefly post my ideas on this problem. Longer posts after the snow flies :-)
1) To heck with transformers; Get a bunch of old color TV shunt regulator triodes and build up a distributed amplifier to deliver the KV directly. Hopefully P-P will be OK? If so ...
