POWERTEC OEM II Model 2B5-3 B 5 VDC supply schematic wanted

[wd5jfr]

Smoke has gone out of one of the resistors and I need a schematic with parts values but can't find one googling.
Any help appreciated.

Maybe post pictures of the circuit board?

I added the circuit board pic but the resistor is under the 10000 ufd cap and I can't get a pic.  I'm not going to tear into it unless I can find a schematic because I don't want to waste anymore time and end up with a basket case.  I'll have to let it waste gravity as is.

standard psu with  lm723 ic,  they are not complicated to reverse engineer ..

[wd5jfr]

It takes time and effort to reverse engineer and the burdens exceed the benefits and at 82 that means less real fun with greater benefits vs burden.

These are old linear standards.  Probably don't need a schematic?  Download uA723 IC data sheet.  There is usually a 2N3055 pass transistor, or some in parallel?
I have many of these in the junk bin from the old days.
The 723 data sheet should show typical schematics.  Check the electrolytics.  Change them?
