Hello world... that is my first post here. I have found this place looking for powersoft schematics. I have K8 on my bench, and some troubles in troubleshooting it. Unfortunately the schematics here are from Digam7000 (which I repaired some time ago after overvoltage accident). My K8 had IGBTs fried, I replaced almost all parts under the PSU heatsink also, and it is still dead. I checked the PSU controll board and it appear to work correctly, but after installing it in PSU it appeared there is no AUX voltage (think it should be 15V). Had someone here some experience with this amp? In the Digam 7000 design there is separate transformer and stabilizer for that, here I can not find anything similar. Any ideas?
Is the .pdf in post 51 the same schematic as the original, password-protected rar file? I ask because several people have commented on the SMPS and transformers, yet the posted .pdf, unless I'm exceptionally dense at the moment, does not include a power supply.
The schematic is nice and all, and quite elegant and complex, yet those supply voltages need to come from somewhere.
If the files are different, I too would then love to receive the password so I can finally see what others have commented about. But if they are the same and the power supply is not included in the set, can anyone point me to the SMPS schematic for the Powersoft amps?
Your must think i am a fool.But You are wrong.It's 100KB difference between two RAR files on 1. and 6. page.Your acting is not correct.But that is Your choise and i DON'T HAVE TO BE HERE.
