21. [AMPS] carbon comp resistors (score: 1)

I think you will do fine using the newer metal oxide type resistors. As part of a swamping network in the SB230, you will see negligable reactance at HF. Also, they do not burn out easily or change v

I felt it necessary to clarify comments on this subject, thus offering MY opinion on 3-500Z series tubes currently available. For the period 1992-1998, 3-500Z & ZG tubes returned to RF PARTS (RFP) fo

25. [AMPS] AC rating vs. DC rating on caps. (score: 1)

I don't recall what an equivalent dc rating might be on oil filled (non PCB) caps. In particular, the Aerovox p/n H83R6654S21, 54 uf. 660vac @ 60 cps. Thanks, Merit W6NQ -- FAQ on WWW: http://www.con

In answer to question as to capacitors used in PS by Commander, they use the LLK2W271MHSB, a 270 uf, 450V, 105 degC snap in. If Alltronics has the LLK2W471MHSB, then it is a real good buy. (Factory p

I have a vacuum variable cap p/n UC125/5/25. Mfgr EEV. It measures 5-125 pf, so that must be the first two numbers in it's ID. What is the 25? (25KV perhaps?) Does anyone have an EEV spec sheet on th

for each of these. For example, on the B3016, would it handle 50 W in? How much over 30 will it handle? The finals in the B3016 are together rated at the 30W drive. It has been my experience that yo

You might be able to find some of the heavy duty transmitting mica caps-- the ones with ceramic body and cast metal endcaps/flanges. They pop up on surplus from time to time for very low cost. ....Me

I have a little practical experience with various "B" & "W" variations. The GE 6146B and ECG-Philips (old Sylvania) 6146W tubes work well in the Kenwood HF transceivers, and have comparable life span

Jeff; It may also be possible your slug blew it's detector diode. The current through the meter movement is only1.4 times the current (at 1 kw) vs. 500W. If you move the slug to point directly up (no

Many years back, Svetlana (Huntsville) marked the same tube with both 3cx & 3cpx numbers. I don't know which design it was. Now, only the 3cx verity available in limited numbers. Svetlana is not plan
