[Test-Equipment] HP-3330B repair: parts needed

[Jose V. Gavila]

Hello!

Well, as I was still waiting for some other test equipment to try to fix my 
HP-8555A, I decided to go for an 'easy one'... well... It is an HP-3330B 
"Automatic Synthesizer" which is a 0.1Hz to 13MHz signal generator, 
modularly built and so very easy to service. As I had replacement for (I 
thought) all the plug-in circuits and what happened to it was just an 
slightly off (a couple kHz) frequency, I thought it would be easy to get it 
working again.

So, armed with the Service Manual, I started troubleshooting tree. It took 
me to locate a faulty VTO module, which once replaced modified just a bit 
output frequency but definitely added stability. Great!!!. Then, following 
the tree and after some checking steps, I got to a point which said 
'Replace A27 Module'. Ok, no problem, I thought... But YES, there IS a 
problem!!!. I have all modules EXCEPT for that one :-(!!!. I have the 
remnants of no less than 3 HP-3330Bs (except for chassis, covers, ...). 
Well, I have all and every card EXCEPT the one marked as 03330-66518 
("SL2/SL3 Mixer/Phase Detector")

I hope somebody will be willing to exchange that module for any other 
HP-3330B module. Any taker???

Thanks and best regards,

JOSE
