Jason,

I wouldn't loose much sleep over your equipment woes.?? Older equipment will always need some repairs or maint of some form or another.?? The equipment you pick up with 'no power' are sometimes the best pieces to get, they have not been tampered or altered from their original designs as much (rogue repair attempts).????Power supply failures or no signs of life??can be the best thing that happend to the machine??because some people just put it away .. on a shelf or in a closet for later review.?? These can be really good jewels or treasures.?? I bought a HP 34401 benchtop DMM (very nice??unit)??with no signs of life and come to find out, all that was wrong with it was it had a??blown .125/250v amp fuse which is the one used when operated on 220V instead of a .250 amp fuse.. so guess what? I replaced the fuse and the rear power input assembly (fractured inside the ITC connector) and shes like a brand new piece of equipment.. even passed calibration
certification with flying colors.??

If absolute worst comes to worst, you may be able to build up a power
supply from available units.
There are some people on this list that has spare power supplies and may
sell one for a cheap price to you. I believe they will enter in contact with
you after this message :)
Congratulations, the 16500C is a great tool, I have one myself :)

thanks for the replays guys. this is realy good news!! i thought i was dead in the water. i have checked the fuse directly by the power socket on the machine and its fine, i also get the red led on the PSU board wich indicates the power board has power to light. currently checking the switches.
i have seen the flow chart in the service manual and it mentions the 120v led on the right hand side of the PSU, mine isnt lit and apparently should be.
feel much much happier now i have joined here! if anyone reading this has a compatiable supply they wish to sell please get in touch i am more than happy to pay a fair price :D.
likewise if anyone wants a pattern generator card(i will get the model number shortly)for a fair price or to do a swap let me know, in all honesty i cant see me ever having use for the generator! it has the cables but looks like there is no pods for the generator.
i will report back soon as i have tested the switches and will look for any on board fuses to check.
many thanks jason
