Col-R-Tel help

[Dave A]

Fired up the Col-R-Tel with Darryl's adaptor using analog in and proper connections for it...using only the V pulse connection and the adaptor RF signal. All others lifted. My wheel has bad commutator springs so this is the best direction. And it has been idle for a few years but for a change of a new belt.

Connected to a restored Philco 50-T1402.

The problem seems to be motor speed. The adaptor tries to make color but the speed is below normal. Using the pushbutton jumpstart I can get it to near normal speed but then it drops to near 1/3 of normal speed and stays there. I ran it for hours and it did the same every time. The motor is its usual very hot condition but not excessive.

It did work in the past in its factory connection condition but the bad commutators sent me to the Darryl converter version. This is just the early version. More testing of tubes and connections to follow along with your guesses.
