Tom Transformers provide power measured in watts. 300 VCT at 250 MA means about 75 watts, plus 250V at 280 mA means another 70 watts. So, in continuous commercial service, it put out about 145W plus
Al... You didn't mention what band the Amp has to run. But in any case, do you know about the Russian Tube QRO site? http://www.nd2x.net/base-1.html jeff, wa1hco _____________________________________
...not sure I understand you're question. These articles shows the block diagram for classic analog pre-distort. http://doi.wiley.com/10.1002/mop.11292 http://www.highfrequencyelectronics.com/Archive
Right. All the voltage need to have low impedance across the audio spectrum. The classic test for uses uses the two tone intermodulation test method and sweeps the spacing of the two tones from about
I had the problem with an 8877 on 2M. The input tuning drifted somehow and having only one adjustment wouldn't bring it back in line. I wanted to design a pi or pi-L network with two cap's to ground

I tried the zero crossing switch on two HV power supplies (8877 and GS35B), both power up just fine, nice and quiet, no blinking lights. Using a zero crossing switch makes a significant difference co
You clipped the test conditions from my original email In some modeling with a 4000V supply with 50 Ohms equivalent series secondary resistance and 20 uFd of capacitance, the single cycle peak capaci
I saw a documentary that delved into the paint used on the Hindenburg. They claimed it included aluminum power and some other chemical (butyl?) that made it approximate rocket fuel. They found a patc
This reminds me of an event during the June VHF Contest. The 432 Station running about 800W quit. It used a DIN 7/16 on the GS-35b amp with a DIN to N adapter. We debugged it to the an open circuit i
I used to think the same thing...but not any more. The Freescale MRFE6VP61 can withstand 60:1 VSWR for 10 msec, which is plenty of time for a simple controller to shut it down. That part costs $271 f
