Rca 8t241

Picked this up last week.

The model has a KCS28 (sams 74-8) chassis. Similar to my 721TS (KCS26 sams 70-7) , cost me alot more but is much better condition.

The main difference seems to be the tuner does not have channel 1 like the 721, but it does have a 4th IF amp and the sound IF is taken off at the 2nd IF amp rather than the tuner. Probably this alone made it a great DX set. It has a sticker on the chassis from a shop no closer than 60 miles to Philadelphia or Baltimore, that each had three channels by 1948. The only "local" station, 15 miles away, came in 1949.

The 721TS's AGC circuit contrasts sharply with the 8T241 (pun totally intended here). Where the 721's contrast control simply varies the bias on the 1&2 IF amps, 8T246 has 2 additional 6SN7s as 2 AGC rectifiers and sync separators plus an AGC control. I can only speculate that the 721TS (found in suburban Baltimore) would generally suck in a fringe area that the 8T241 seemed to be designed for.

Both classic sets are missing the classic items, back covers and HV cages The 721 TS needs channel knobs also.

I don't plan on powering anything up until all Electrolytic caps and some select paper caps are replaced; damper cathode bypass, two at the vertical output grid are prime suspects.

I save all the old stuff yet have little time or motivation to re-stuff caps as some artisans here do quite well.
