Q431 is un2212 in the parts list, a "digital" transistor.
On the schematic it shows un2212-x.
I think it was superceeded by DTC124.
I have one of those I can drop in the mail.
Is that the Roosevelt Rd location?
Sure would like to know the voltage readings on each end of R553 when
you get it running.
