thing ?
>   I have one,that needs some minor work,and I was wondering if it had any
merit for serious listening.I have had it sitting in a closet for
years,(Ever since I stole it from an abandoned roller rink,some homeless
guys broke into.)and have not found anyone willing to work on it,as everbody
says they have never heard (of) it,so therefore it must be junk.Emails to
vintage audio sites,have illicited similar responses.It appears to be an
amp,and preamp,in one,what they call an intergrated amp,nowadays,I
guess.While I'm at it,I have one of those Hewlett-Packard oscillators,of
WWII vintage,identical to those used on "Fantasia".(Twenty bucks at the flea
market,in 2002.)This has Western Electric amp inside,as well as functioning
WE tubes.Is there a WE model amp, comparable to this unit,and what would it
be ? Roger Kulp

Make/model number of your "mystery amp?" Note that these old "Public
Address Systems" included by definition both "pre-amp" and "power amp"
stages in the same chassis...so you could plug a mike, record player
or radio into the proper input jack and have that heard all over the
auditorium/skating rink/wotever. BTW...what is the tube line-up?

Most of these amps weren't built for "high fidelity"...they were
simply built to provide power enough to feed an array of speakers.
As their "public address" name implies, their bandwidth was aimed
mostly at reproducing the human voice as well as to reproduce
records (volume was more important than fidelity).

Repairing them is only a complicated task if/when replacement
parts are needed (including tubes!). Tube circuitry often used
components rated at 400 or 600 volts...and modern soild-state
circuitry doesn't use such components!
