I'm buying a few to fix my 170B unit and was wondering if anyone wanted some spares. At a quantity of 10 they are only about $4.50 each. I'll also be getting some replacement TVS zeners, so if you want some let me know.

The part in my unit: IXFH26N50

The subsitute part: SPW32N50C3

Send a message soon cause they will be ordered Monday.
