Title: Bristol amp chassis
Post by: N8ECR on June 06, 2006, 09:14:52 AM
Ok!!  Here is one for all you audio crack pots out there:

I picked up a small/cute ampilifier chassis made by the Bristol comp. in Waterbury Mass some time in the mid 60's. it is a type 10L  with two 6EU7 's, and one 6BQ5 tube in it.

Does any one know what the input impedence is????

what is the relay thinggie; called a" syncroverter" used for???

I notice there  is no output tranney, so was this a pre-amp of some type???

What did the thing come out of???

Does any one know a source of a diagram, or any other info??? :-\

Post a jpeg?
That will give some clues...

If that doesn't work:
Trace the circuit, that will tell you what it does... or doesn't.

The syncroverter makes me think of a vibrator supply type thingie... but that's a "remote association."

It is spelled Bristol.  Bristol Co. of waterbury Conn.  The thing is in a modual format for quick chance or maintanance

The Syncroverter is most likely in the input , that is the way it appears to me.  I am thinking it came out of a piece of test equiptment, or a tape deck, maybe a lab piece???

May have to post a pix of it???
