    Pioneer SX 1250/5590... Yes, HOT... But how much?

    Hi guys, I have read here many posts about these "little beasts" running hot at the right side, just over the stabilizer board. I just changed some of very well known noise signal transistors in my beloved SX 5590, regulated the stabilizer voltages, checked the DC offset, and set the bias at...

    OnSemi ThermalTrak power transistors

    OnSemi finally did what so many have suggested and put a matched bias diode junction in the same case as the output transistor. They call them ThermalTrak and is a 5-pin TO-264 case. No more bias lag issues. I will have to try these out. Datasheet attached.

    Temperature of Fisher 800C power transformer

    My Fisher 800C power transformer measures about 129 degrees F which does seem pretty hot to me. This is not mounted in the wood cabinet. If you guys have time and a laser temperature probe, could you share your temperature readings. Voltages measure at the correct levels in my unit.
