This request was soooo polite I took care of it immediately. I think someone subscribed for him without his consent and now he is asking for assistance to unsubscribe. His wish was granted. 73, Mike

From the few minutes I was on the new Ten Tec website, they are going to service the newer Alpha Amps. They listed which Alpha Amps and Ten Tec radios they would support. Oddly, Orion 565 and Orion 5

I for one, will wait for the next generation of contest grade transceivers. I do like the concept of the IC 7300, and I might play with one as a replacement for my TS 590S which I use for portable op

Firstly, does the idling current change from standby to operate? If it does not change, and remains the same, you may have no bias at all. The triodes are zero bias tubes and will operate with no bia

Ok. Your tubes are not biased. This is not the way they would have built the amp. Depending on your meters accuracy, zero bias might allow 140 mils max. You have no cut off or operating bias. I don't

You can check the match both statically and dynamically by installing one triode at a time, and double checking you don't short the unused plate cap. Follow all safety precautions and all interlocks

Why not equalize the grid current for each tube. Small resister to ground should do the trick. Some folks turn it into a grid fuse by using a very small wattage resister. If the grid current goes too

I've already done it. I've also tried the grid fuse as well. My SB 220 has the grids strapped like this. See Richard Measures pages pages on SB 220 mods. Seems to me he is the main advocate for this.

Here you go, read the last sentence Mr. Measures writes here: ANODE AND GRID GLITCH PROTECTION A glass-coated resistor can serve as a peak current limiter between the HV supply and the anode circuit.

Actually, I tested many of his concepts on my SB 220 which I built around 1967 or so. I do not ascribe to them all. His theory on VHF parasitic oscillation has remained a topic which is still controv
