modding Sears 934-36772600 23ch SSB/AM

#367327

Post by yonubear »

hey all I am hoping someone can help me out I decided to dig out my old sears CB and see how far I could push 4 watts using my 10m antennas and tuner but I figured i would clean it up and make sure everything was right and bring up the ssb mic gain a bit. The problem I am having is the modding guide I founds says to adjust R86 however I can't find R86. I am hoping someone can shed some light on the location of the pot.

Thanks,
Yonu

Hello yonubear,
Welcome to the forum. Here are the tuning points for your radio,
Sears 934.36772600:
R17-AM Sens, R62-SSB Sens, R231-SSB AGC, R37-AM Sq Range,
R260-SSB Sq Range, R262-AM S Meter, R263-SSB S Meter, L13A-TVI Adj,
R405-Voltage Reg, R86-SSB Mic Gain, R281-ALC, R264-TX Meter, D25-AMC Defeat>
TX Tune-up: T10, T11, L13B, L14, L10, L11
RX LSB Tune-up: T9, T8, T7, T6
RX AM Tune-up: T5, T4, T3, MF1, T2, T1, L1
At looking at the points R86 might be just a resistor and not a pot, looks like the pots start with the number 2.

thanks that is actually the list I had but I can't find any of the listed points I was hoping someone here may have modded one in the past and could throw some light on the subject.

Thanks and 73,
