|NOTES||One of a range of similarly styled signal generators, the
J1 (and J1A) being aimed at the communications engineer. The Advance J2
is similar but has an aditional output meter.
Suprisingly, for such a low frequency, the oscillator circuit is actually tuned via two ganged variable capacitors.
|SERVICE DATA||I got a copy of the original service manual (part number 7773) about the time that I bought the generator but I can't remember where from. You can download a copy in .PDF format from the service data page.|
|CURRENT STATE||The insides are absolutely imaculate, as if it had never
been used. After reforming the main electrolytic capacitors, I gradually
applied power and presto! worked perfectly.
The case is a little scratched but still has original labels attatched that indicate that this generator originally saw service aboard HMS Mercury.
|WHERE FOUND||An amatuer radio rally around 15 years ago|
