[Amps] Amp Pricing(??)

[jim.thom jim.thom@telus.net]

Don't even think about installing CHINESE  811'a horizontally into any
30L1. Cathodes will sag..and short.  The only thing that will work in a
30L1 is chinese 572B's.

Chinese 811's are piss poor at the best of times, they don't hi-pot test
very high.  Typ on ameritron AL-811 amps,  572B's  are used for tube
replacements.

Rob nailed it. Stick with old school 3-500Z amps.   They are very easy to
maintain, and easy to modify and upgrade.   Stay away from megabuck tubes
like 8877, 3CX-800's etc. Both have floozy grids, and require grid
overcurrent protection.  I would stay away from russian tetrodes and
triodes as well.
