Help with 1930'3 Philco resistor codes & tube pin ID
#1

Let me begin by saying I've restored quite a few all American five's as well as multi-band trans-ocieanic clones, so I feel like I "half" way, know my way around a chassis and schematic.

I currently have a 38 Philco on my bench that I recapped including the Bake lite blocks. I'm trouble-shooting a problem that seems to be in the IF stage.
I guess I'm spoiled but, I'm having trouble reading the resistor color values on these old radios. They appear to be spray painted on. Also I'm used to the pin numbers or tube keys being printed on the schematic.

Maybe some of Mr Schwark's service info would be worth the purchase.

I've always used the Riders and Baitman's schematics.

Any suggestions to help my vertigo would be appreciated.

No rush I'm out of town this weekend. Thanks in advance.

You can look up the tube basing here:

and Chuck does have resistor info on his site:

Why do you need to know the resistor codes if you are fixing a radio? All you need is the sch and a meter to confirm that the actual resistor is the requiored value. Yes - leave ity, no - toss it.
All the sch may be found eitgher here or in Riders manuals, on the Nostalgia Air website.

Thanks guys for all the help. Ron this is exactly what I was looking for.

Morzh, I will try to make this as polite as I can. I agree, one can always find resistor values by studying the schematic to figure out what it is. I find it much easier to read the values off of them then compare to my meter reading. When you say why do you need the readings off the resistor, I would ask, why did they put them on there then? I know some are hard to read or interpret but the statement that you don't need to read them seems, well, less than appropriate. Of course I have been wrong many times. Take care.
