[Premium-Rx] PLESSEY PRS2250 HELP WANTED

[paul at paulg8gja.free-online.co.uk]

Hi Dave,

A quick look at the reference in my spare chassis (luxury!!) showed that the 
pin connections are as follows :-

pins 1, 6       gnd
pins 5, 8       +ve supply

I think the supply is around 12v (it feeds the crystal oscillator [cathodeon 
tcxo,   fs5953-01-00, 10MHz] and a 7805 regulator for the /10 stage) but as 
the manual has gone AWOL at present I cannot be more precise.

Hope this helps,

Paul        g8gja
