Hi!
Will this manual I've attached here help?
There are five secondaries:·
1) 30V @ 100mA :– +37V VFD Anode supply regulator;
2) 1.55–0–1.55V @ 250mA – VFD filament supply – VFD filaments are typically 3.15V nominal;
3) 10V @ 1.5A:– Front Panel, Main board Digital and "in guard" analogue supplies;
4) 18–0–18V @ 250mA:– "Out–guard" (floating) ±18V analogue voltage supply regulators;
5) 10V @ 250mA:– "Out–Guard" (floating) digital and interface circuit regulators.
Windings 1 to 3 and 4 & 5 need to be screened from each other and insulated to withstand 1.5kV between them, as the "in–guard" (microprocessor, display and logic controller) need to be insulated from the "Out–Guard" (floating input, amplifier and a/d conversion) circuits are at the potential of the floating input terminals, which are rated for ±600V relative to true earth!
If you go on the UK Vintage Radio Restoration Forum, (you will have to register to post) and contact Member Ed Dinning, he can rewind your transformer for about £80– £120 for you, or you might like to contact Array with the transformer details given in the parts list they provide – I believe they're willing to provide parts on application!
I will be beginning the job of tracing full circuit diagrams of my 2100 in the (hopefully) not too distant future, but until I have the time to begin this, you might like to look on the "xdevs" Keithley and HP repair site, schematics of the 2000 can be obtained from there!
