Hi,
A friend of mine needs to repair the power supply of a TRS-80 Model II.
I've found a schematic but without part numbers and values! He needs to
know the type of transistor Q1, there are no markings on the case of the
transistor. I've checked the power supply of my Model II, and there are no
markings, too. The Technical Reference Manual has all schematics for the
Model II, but the schematic for the power supply is useless without
component values. Might a BU208 for Q1 do the job?
