Ah geez, I try to keep a good stock of parts, and a good selection, but...
Rebuilding a Bassman 250, which has a power amp of the same general topology as that FM212R we discussed at length a while back. Overly complicated. I think I have it daignosed, but there are some pretty specific semiconductors in it, that I don't have. SOme MPSW42/92 types that have to be in thermal contact with each other, and they are in the 1 watt TO92, some shottky diode, a couple other diodes, some small zeners I was out of particular values. Even buying 25-100 of each thing I still came in under $20. But it is wednesday AM, and I need this amp ready for saturday pickup by out of towner.
I looked at next day saver, but that was still $40. So I went for cheap, figured 2nd day still gets them to me friday, which should work out. And "only" $18.
I hate it when the shipping costs more than the parts.
