3000a Pre Power Board

[Hebridean]

A couple of the 2sc696 or 2sc756 transistors on my board are goosed and I’ve seen the Ksc2690a and the Tip31c being recommended. I’ve got both which are holed but only the Tip31 has a metal back. Would I be right in thinking the 2690a would get too hot even though they’re attached to small metal plates?

Thermal transfer should be similar if use thermal paste on the 2690's. That is if power ratings are equal. Without looking at the specs of each you mention, I would think the component with ability to handle more power and wattage would run cooler.

Many thanks for your reply JD and I've decided to go with the 2690's as I've seen posts where people have used then in the 3000a, but no posts for the TIP 31's though I reckon they'd do the job. So I'm it playing safe!
