Good luck finding that. I have the service disc for this unit and there is no such schematic. It is treated like a black box. Spellman will not talk to you about this either. I tried. Are you sure you have a bad power supply. Usually the tube goes not the supply. Sorry I couldnt be of more help.
I have attempted to find comapnies to fix these things and also tried buying them direct from Spellman. No luck on both counts. If you happen to find somebody that can fix these things that would be great. Other options would be to buy an used one.
Good luck
Be careful with Ensil International, I once sent them a board for repair and paid $800.00. The board was not repaired and they have refused to refund my money for the last four years.
Wow! I can't believe that. Sorry to hear about that. I haven't had a problem with them as of yet. I always wait for a quote before repairing and if it fails within the warranty I send it back.
I have had some troubles with spellman power supplies. One time the damage was as obvius as the solution, but the rest were a waste of money and time. Spellman is a company that produce generators for industries that solicite them do not submit any technical information about the device them produce. A way to ensure the hi quality of service they said.
An spare unit is one solution but be carefull. Often, this P.S. are matched with another piece of the equipment.
First of all find out what exactly the problem is.
According to LUNAR service manual and my 15 years of experience on DPX systems the source of your problem could be almost everything: MAX board, cables, pole arcing, bad X-ray tube, bad HVPS, xorb board even a bad command from sbc board. Let me tell you that there is no other way to find out what exactly the source of the problem is than to replace the above.
If you are sure that the problem is in HVPS you have to find out whether the problematic is the positive one either the negative one (or may be we could examing this on your behalf).
If the problem is in the control board we can fix it 100% percent, if it is in the covered -power area we can not garranty that we can fix it. Normally we test them in vitro and in vivo for at least 2 days and we can send you a service report, LUNAR QA test or LUNAR service test. We follow standardize procedures according to ISO 9001:2000 standards.
Alternately we can also provide to you a replacement.
Regarding the alternetive proposed that is buying a new one from Spellman, I can tell you that it is not a good idea because the HVPS that lunar uses are custom made. Also using one of this is more likely that you will have a great damage.
Carlos I think that we have spoke in the past for Lunar systems so you have my e-mail and you may use it for further details.
