I replaced R4151M with 1k-1/2w and the new one blew.
I come to find QX3404(121-1102) shorted E-C, but I'm not sure if this caused
the new resistor to blow, or from another fault somewhere. I am working
without a schematic.
If anyone has ideas, or can fax portion of prints, I would be appreciative.
Thank you.
