one sees obliteration, it usually means VHF oscillation. ### No it doesn't. With his 3 x paralled 15 ohm resistor's... it means he has 5 ohms in total.... and the wrong value to start with ! The goals

no square in the equation... C = k * ( area/distance) k is the factor for insulator dielectric factor () is the ratio of the plate area divided by the distance between plates denny equation.

Hello, Jim. == In a VHF parasitic suppressor, when one sees obliteration, it usually means VHF oscillation. The goals of a VHF parasitic suppressor are to build one with a low VHF-Q that won't

Jim, If you think you need a B- fuse, put a 500 ohm 10-25 watt resistor across the fuse incase it opens. You should also have a 100-200 Ohm 25 watt B- lead to ground in the power supply and the 1 ohm

Im working on fixing up a L-4B, it has fried resistors in the supressors. They use 3 x 15 ohms but I have none in my junkbox however I have plenty of 10 ohm Rs, will that do? 3 x 10 ohm Rs? It doesnt

was ## I USED to own a FL-2100B new.. back in 1977. It did not have 160m in it. The xfmr ran hot, with just the fil + fan + hv on. Turns out they all do. [xfmr was a combo plate xfmr + fil xfmr] ###

The 350 V rating on 3 watt 100 k MOF resistor's on digikey's site does not indicate if this is ac or dc.. I'm assuming it's AC RMS.... if so... the DC V rating should be 495 V ??? On a similar note

something that thoriated-tungsten filament tubes do not need because their emissive layer (di-tungsten carbide / W^2C) can not be damaged by too much cathode current - as is the case with oxide

Does anyone have any experience with the new Alpha 8100? Pickings on the website are pretty slim. The link to the manual is not working and all I can find is a one page brochure. Is it in production?

However, during the 9-years when Bill Fisher, W4AN, was among the living, AMPS did a fairly good job of providing a venue where old farts could pass on what we knew to the new crew. cheerz R L
