[Elecraft] Slightly off top amp question

[Geoffrey Mackenzie-Kennedy]

David,

In addition to Vic's and Pete's suggestions, take a close look at the plate 
choke for any signs of localized heating, ancient or modern.

I'm flying blind without the schematic and am assuming that the amp has a pi 
output network with a RFC at the high Z end for DC feed.

73,
