Notes on T29

T29 is for band 5 in the oscillator.

Early Radio, Round Coils

Calling this T29 is still being questioned.




Stamped with part number 51294. I don't have a parts list for the early radios that give anything other than resistors and capacitors.

A diagram identifies this coil as "B5-S9"

Letters are for table below only.


Resistance measurements made with 4-wire ohm meter. At these low values, even the tarnish on the terminals plays a part.

		A to B (center tap): 0.02 ohm
		B to C: 0.02
		A to C: 0.03
	

Late Radio, Square Coils




Stamped with part number _______.

NOT PHOTOGRAPHED YET

		Winding 1: _____ ohm
		Winding 2: _____
