Hi

Does anyone know where I can find a detailed schematic for a Grunow 670 tombstone, some early repair work has got me confused as to where electrolytics go..Thanks Jeff

Jeff,
If it's a Grigsby Grunow, you can find the schematic here:

Actually, that is for a model 370.
For the 670 try this:

It looks like it could be right however what I really need is: a cap list. The electrolytic caps are in a box, I believe there are 4 of them, someone replaced a couple of the caps by cutting wires on the box and replacing. I think only one or two has been replaced. (an old repair at least one paper cap installed) I guess what would help along with the schematic is a cap list s o I can tie values to cap numbers.
