I once saw a guy break a plate off button when someone behind him stepped on a sheet of bubble wrap on start up......... I still look around the room before I press the smoke generator..... LOL !!!
I like Carl's perspective. Sometimes, all the theory in the world won't put a watt into an antenna. Don WA4NPL _______________________________________________ Amps mailing list Amps@contesting.com ht
Between the two, I think I prefer Carl. Don WA4NPL _______________________________________________ Amps mailing list Amps@contesting.com http://lists.contesting.com/mailman/listinfo/amps

The safety choke should be "transparent" on all bands. If tuning changes, suspect the choke. Don WA4NPL _______________________________________________ Amps mailing list Amps@contesting.com http://li
I think it is more important to keep filament voltage at or below 6.3vac. Before modification, mine on a 30L-1 was over 6.9 standby and 6.7 under load. Don WA4NPL ____________________________________
Guys.... this is a great scope. I've used one for over thirty years and you can check everything from DC to 2 meters. One tough Oscope. Don WA4NPL _______________________________________________ Amps

I had four in a 30L-1 look alike. The control grids were above ground with ( if I remember correctly ) 100 ohm carbon resistors. Don WA4NPL Quoting K8MLM@aol.com: ____________________________________

I had a 30L-1 "lookalike" that used four 250Bs in GG. The control grids were grounded through resistors and the screen terminals on the sockets were bent over and soldered to the metal socket. Don't
I have a pair of 30S-1s, and I always thought that the ALC circuit was like shutting the gate after the horses had already run through..... gotta make grid current to prevent grid current... but neve
One gets away / some get stopped / one gets away / some get stopped ( repeat-repeat-repeat ). I would prefer an ALC with a variable conntrol that could be adjusted to limit the exciter *JUST BEFORE*
Scrubbing Bubbles works wonders on Commercial Broadcast transmitters that have been in harsh environments... Melts the dirt right off. Don WA4NPL _______________________________________________ Amps
But did anyone come up with the original article of using 4CX-250Bs in "semi" grounded grid ? I believe my amp used 100 ohm 2 watt on each grid to ground with the screens direct to ground. Don WA4NPL
There will be some loading when the meter is paralleled across the bottom 1Meg. Also make the lower resistor out of four 2 watt resistors in series-parallel. If one of the resistors opens up, you do
So..... should we be bandswitching the rf choke ? Metering the bypass capacitor's rf ? Don WA4NPL _______________________________________________ Amps mailing list Amps@contesting.com http://lists.co
