ABC Tube compressor

[synthi]

Hi Mates,

I just got a strange tube compressor. Its a A.B.C. Television audio compression amplifier. some p*rn here:

The 4 tubes are ECC81, ECC82, 6BE6 and EF (91?).

now I need to get those cannon connectors, does anyone know where could I got them???
Also Do you know anything about this units? Because the -20 pad I think It could be used for both mic and line input but the audio trafos are those black cilinders and don`t have any mark, no numbers, nada....
Also, I think its a variable mu compressor but may be you can throw some light checking the internals.....

Thanks!

Synthi.

I know that Sommer Cable in Germany sells them. They are called "EP". I've seen them on some high-power PA systems.

Maybe it's easier to replace them?

sweet find.
this thing smacks of RCA/UTC.

the trafos look a lot liek the ones UTC made for RCA. there may be some numbers on the bottom of the trafo. where the leads are.
as for the vari-mu thing I don't knwo but knowing the US equivalent to those tubes might help since we do know of some tubes that are definite indicators of a varimu design. (like a 6386)

any way nice gear thanks for the cool pics
later

The Plessey cap and the EC- tubes make it more likely a Limey machine (?)

The components do look kind of British to me. The resistors are like those found in a QUAD II power amp, & some of the other caps look like they might be HUNTS. Most of the valves appear to be Mullard also.

From a google search, article about Sydney Newman: "In 1955 commercial television broke the broadcasting monopoly held by the BBC, and ABC Television Ltd. was a regional company given the franchise for supplying weekend programming in the North and Midlands."
