I'm on the trail of getting an Ameritron AL-572B - new, from the HamStation. Just wondering if anyone had any recommendations against getting this amp. I have thought about the 3-500Z AL-80B but have

2. [Amps] Maximum tolerable SWR for dual 3-500Z amps (score: 1)

Is there a rule of thumb for maximum permissible SWR for 3-500Z amps at given levels of output power? Say, 300 watts for 2:1 SWR or 800 watts for 1.5:1 SWR, etc? For SSB and CW modes? _______________

I did some searching through the list but haven't managed to hit the nail right on the head yet... For wiring a Ten-Tec Centurion amp to 220V, are there any recommended plugs and outlets to use? I am

If the Centurion has a 4 wire power cord: I will tie the chassis ground to the ground in the feed, the amp's bond to the feed's neutral and the 110V single phase lines to the amp's black/red. The ide

We got a good rousing set of replies on how to wire 220V, maybe we can strike gold again on this one... 3-500Z plates - I'm reading that they "enjoy" getting dull red hot. My first ham gear was a Dra

Okay - I had read it the wrong way then. I read it as though the energy striking the plate (and not the movement through it) was creating the heat. I wasn't totally sure about that. Wow - so regardle

That's a classic. The fan motor for the tubes is a motor used to spin a turntable out of an old 70's Philco console/cabinet record player/stereo. I bet Rich would have fun with this one. ;-) 73 Jason

What's the grid current at that point - 80mA or thereabouts? Plate current? I had a couple QSOs early this morning on CW and noticed that the plates begin to show a faint bit of color near the bottom

I wonder why grid current is measured instead of dissipation - I would think dissipation and current measurements could be easily interchanged for display on a meter. Interesting - I thought Ep dropp
