In another life, 20 years ago or so, my employer was using Tripp-Lite yellow domed strobe lights for their construction vehicles. One day, I was visiting the central garage and noticed they had 5 Tripp-Lite strobes on a bench. I asked the foreman why, his reply was because they had crapped out and hadn't been tossed out yet. I asked him if I could take them back to my shop and he replied 'Yes!' Fast forward a bit ... I analyzed the problem of each strobe light, determined there was an early version and a later version. Quickly, I discovered the problem of each strobe light, used the unrepairable units parts to fix the repairable ones and returned the repaired units to the central shop a couple of hours later. From then on, I got all the strobe lights for repair. I didn't need to contact the manufacturer as the transistors used were fairly obvious from a bit of study (Motorola) and the rest of the parts were available from the dead strobe units or the distributor. (flash tubes) You might want to study the internal workings of your power supply in case the problem is obvious. Good luck with your project, Neil - WA6KLA
