Hi Mark,

I'd say about a million candlepower!   Thanks so much for your detailed 
reply, which was exactly what I was hoping for.  I guess my estimate of 
the amplifier power was fairly close ;-)   Thanks also for the speaker 
info, which makes sense given the design intent.   Right now I've got it 
playing through a pair of Heathkit AS-193 speakers, which are a bit 
unique in that they're about the size and shape of a big city phone book 
and hang on the wall.  But they sound good and the KLH drives them to 
what we used to hear described as "room-filling volume".

Initially I thought one channel was dead and was dreading the need to 
potentially find new output transistors, but it turned out that my 
speaker wiring was the culprit instead, so I fortunately dodged that 
bullet.   I recall back in the 70s a company called Germanium Power 
Devices was consolidating the production of almost all the germanium 
product from RCA and others who wanted to shut their lines down, but I 
see now they' only make specialized opto detectors so I doubt there are 
any suppliers of new germanium transistors left on the planet.  So I 
guess we better take good care of the ones we've got!  

I am surprised (in a good way) to have a reply from a true authority 
like yourself, and certainly appreciate it.  Having worked  for an 
electronics company both before and after a major corporate "culture 
change" I can relate to your "good years" comment as well.   The 
original KLH left a great legacy.
 
Thanks and 73,
Bob W9RAN
