I am looking for a second amplifier. I have some questions....
1. Why are there very few AL-82 amps for sale on the used market? Either
they are turkeys or great amps. I think they might be a great amp. 2 x
3-500Z is pretty simple.
The AL-82 is a good amp, Al-1200 better and Al-1500 best
2. Amp Supply - are they any good and what is the pit falls with these
amps. Seem to be straight forward design. Not a bad amp, but hairy on the
higher bands, simple
3. I get a little concerned about amps that use "ceramic" tubes. My
experience has been with "glass" tubes like the 3-500Z. I get a little
as to the availability to some of these tubes. I know that some manufacturers
have gotten on the Russian tube band wagon and then the source seems to dry
up. I am concerned about the cost of re-tubing...the life of these tubes
(could be years or decades I am sure) and what the deal is with the Russian
tube vs Eimac thing is all about. Why is there such a move to these types of
tubes? Good ceramic tubes are 3cx800 and 8877's, there are plenty of pulls
around, no problem. GS-35B Russian tube not bad cheap. Others less power
harder to get. You want tetrodes???
I am just doing some research and asking questions.
