AMPS Reflector--
Rich Measures said on July 2, 2001:
"Low Rp parasitic oscillation suppressors apparently work. The Alpha
86 & 87 does not use such suppressors. Around 40% of the 80-series Alpha
owners I surveyed reported sudden failures that required factory repair.
When Alpha founder Mr. Dick Ehrhorn was active on AMPS, he said that he
had seen hundreds of tubes with gold-sputtering damage."
This didn't sound like a correct attribution to me so I forwarded
the quote to Dick Ehrhorn to confirm if this is what he had said
or what he believes. And this is Dick's reply:
"Measures is simply unbelievable & evidently clean out of his gourd now. We
had long exchanges on the amps reflector concerning tube failures. I made it
100% explicit that I had NEVER seen, or been made aware of by a credible
source (i.e., Eimac or our lab), of even one 3CX800A7 (or any other tube
type) failure which was attributable to parasitic oscillations in any ALPHA
amp."
I just wanted to clear up this misinformation and misrepresentation
of Dick's position on the issue.
