Hello all, I'm rebuilding this old amp for a friend. I'm working on getting a schematic, but in the mean time I'm replacing all the caps and will begin testing all resistors.
I have a few parts I need help identifying. The first is certainly a ceramic power resistor, but I don't know how to read it's markings. The second is, well, the picture speaks for it's self.
The only other parts I'm not sure of are two large resistors but I don't know how to judge the power rating by thier size. One is about 1.25" x 1/4" and the other is 1.5" x 5/16". The first one is pictured.
It's bands are Yel,Vil,Orn (I think)
The other is Red,Vil,Brn (I think) But it reads 450 ohms.
As far as the bulk of the resistors, is 1/2w adequate for replacement of the smaller carbon ones?
Yes indeed, a schematic would be nice.
Thanks!
