[Hallicrafters] Hallicrafters S-107 Mark 2.

All the work on this radio is done and it's tuned up and back in the chassis.


I changed all the Tiny Chief capacitors with modern 630V Metalized Polypropylene Film capacitors. I also put new electrolytic capacitors under the chassis. I also changed the speaker. The original Speaker appears to have gotten wet. It sounded poor. I found a  replacement speaker at Parts Express, (www.parts-express.com). The speaker is a BOSS BRS46 4" X 6" Dual cone replacement speaker, $6.39.  Now the radio plays fine would a much better sound due to the new speaker. I did have to open up two of the speakers mounting holes a little with a round file. I used 3/16 inch spacers between the speaker and the radio.

I checked capacitance value of the old capacitors on a HP 4261A Capacitor meter. They all measure on the high side of the correct values. I also checked the leakage at 250 volts. The electrolytic and one Tiny Chief have 5 ma of leakage. The other Tiny Chief capacitors have 0.1 to 1 ma of leakage. 


Thanks for all the comments about this radio.
