Please excuse if this is off topic but if you think it through I think it could be argued as amplifier related, sort of.. I'm in the process of importing a radio, doesn't matter what but suffice to s

Hi Terry, I think you have experienced one or more not uncommon problems with a number of 3-500 amplifiers. The re-soldering of tubes base pins is a common sight and though highly inappropriate I thi

I wonder, would it so happen that the mounting holes for the SK-410 might just be the same as those for the Johnson 275? I think real sockets might have made it on to my list for the Henry rebuild fi

Does anybody have a scan, or other electronic version, of the Titan psu, this is the one with 2x3CX800's in it. Got a fried one here but no documentation. Many thanks Martin, HS0ZED _________________

I'm not particularly interested in 50MHz, no allocation here, but even at HF I think conversions could be further explored. I have an Alpha 78 and whilst it does work, sort of, 1500 watts at 100mA of

Thanks for all the useful thoughts and ideas about my drifting grid current. It doesn't drift at the moment but that is because it will not switch on Whilst trying 15M at about 1200 watts it went pop

I have seen this meter mentioned on here a couple of times before but cannot locate any information. The user manual talks about calibration and the need for 'special equipment' and the procedure bei

Perhaps a question for the Heathkit history buffs. Did the tune capacitor change during the life of the SB220 or perhaps with similar amplifiers? SB200 HL220 etc. I have received a replacement capaci
