"Ron Baker" <[EMAIL PROTECTED]> made an utterance to the drakelist gang ---------------------------------------------------------------------- Ken, the TR4 has an 0A2 regulator, its a gas filled tube used to regulate the 150VDC voltage line. Its normal for the tube to glow and the glow varies with the amount of regulation needed.
2nd question, by all means turn off the radio when not in use, what is the point in leaving it run for long periods of time when not being used. The radio was designed to be shut off, thus the off-on power switch. Tubes have a definite life cycle and are rated to function for a certain number of hours before failing, usually thousands of hours. But like a light bulb, they will eventually fail due to use. The excessive heat alone could due more damage than the stress of turning the radio on and off. There is a certain amount of circuit and tube stress when turning on and off the radio, but if that were to occur, its a safe bet the failure was ready to happen anyway.

I worked 2 stations in Serbia on 20m SSB (one was mobile), busting right through a pileup on sunday afternoon. Love it! Anyways, I noticed that V20 had a neon blue arc at the top for 5-8 seconds when I first turned on the rig this morning. Looking at the schematic V20 appears to be a voltage regulator. I've got 2 questions: 1) Where can I get a replacement? 2) Should I leave my TR4 on from now on? 73's de Ken KG0WX - Kadiddlehopper #11808, Flying Pigs #-1055, Grid EM17io ____________________________________________________________ _____ Can you find the hidden words?
