Hello Niels,

A lot of older gear like that relied on mechanical contact with
screws, etc, for grounding - and as the gear got older the contacts
turned into resistance or in the rare case even crude rectifiers,
causing all kinda strange effects...

 NP> We used 3055's in a batch of 100w audio amps at one stage. (60V rails)
 NP> One clown hooked extra speakers up to it and ran it on a 2 ohm load.
 NP> The amp just kept choofing for 2 hours until the heat was sufficient

 NP> blew the fuse. Even after all that, the 3055's were still OK !!

Yep, electonic components can take a lot of abuse, when it suits them...
at least the EL34's and KT88's can take that sort of punishment,
just don't operate the PA without speakers ;-)

 >> No probs.  If Dieter does manage to clean it up a bit, btw,
 >> I woudn't mind a copy myself to keep the collection intact.

 NP> When Dieter lets me know the file name I will get it from TML and send
 NP> you a copy.

Ask him to email it back to me.

Regards,
Chris.
