Just for the record, I'm attaching the datasheet for the TIS58. It's pinout does not match the interfet 2N5484, nor the on-semi or centralab 2N5484. So that's 3 possible pinouts for the Randall Fet's.

Quote from: Jesse on May 07, 2024, 04:01:33 PMQ9 has fresh thermal paste and seems to be tight to the heatsink.What about it's insulator? Don't it and the output transistors that are mounted on the heatsink have mica insulators or similar?
Quote from: markorock37 on May 07, 2024, 12:59:57 AMIs it possible the new ones dont have the same pinout as the originals?Yes it is possible. Measure resistance from D4 cathode to T5. One of the T5 pins should read zero ohms to D4 cathode. Which pin is it, pin 1,2, or 3?
