| Pioneer SX-850 Transformer Secondary Output Voltage Although 20.6V on each green wire and 48.4V on each orange wire seems a little high according to the schematics of service manual, I think it's OK since those windings connect to voltage regulator circuitry after rectifier. The 33.1V on each red... | |

| Cary V-12 blowing capacitors The original power transformer that was in it had a direct short and could have caused the UCC’s to stress. I thought the opposite, shorted filtering caps stress upstream power supply components ( rectifier diodes, power transformer and fuse ) ... | |
| Cary V-12 blowing capacitors I asked him why he thinks the black UCC would explode and he said the only way for them to explode is if they were wired with reverse polarity. Or if they were wired with shorted rectifier diodes. | |

| Accuphase E-480 Congrats! @sp33ls2 One thing I was a little bit surprised by was that some of the rails to the power amp board were raised by a few volts (like 65VDC to 69VDC) when compared with the 100V step down... My AC mains are 122VAC rather than 12... | |
