the two resistors I can see, likely R5 and R6, the vertical "GBY" and "RRG", I couldn't quite get their values from the code, they should be 220K and 330K, were really out of tolerance, especially the GBY which I think measured as 1M+, and 220K was 360K. I paralleled them with some resistors to bring them into compliance but was not sure in teh first place of values and if the radio is 100% compliant with the sch. R9 (Brown-Red-Red body) measures as 1.2K (correct) though says in the sch it is 2.2K.
Also there are some discrepancies, as I said - the R7 and R8 are missing, and so are C5 and R6, plus the outputs 5 and 6 of the 12AT6 are shorted and the R2 is missing as well. The R4 was replaced by Kirk or someone else to 6.8M (is 10M by the sch) which is OK, does not matter much. This is the one I replaced with 100K right now to bring down the hum. The radio looks exactly the same, all the parts and the chassis are, even those 220K and 330K resistors and the IF transformer look the same.
Also the antenna coil hookup is just a smidge different.
But then again, our radios are Sterlings and the sch from the Teletone. Close but not exactly the same. Yours is closer.
