Hi
I was recently given a Motorola 17T21 by a family member an am looking for information on it.
It is missing all of the knobs except the power volume knob which it has.
Anything to watch out for when restoring this? I have noticed that the yolk cover will need replaced. Aside from that and the knobs it looks complete.

I bought and sold several of the Motorola 17" sets, most of them in the bakelite table model cabinet.
IIRC, they made about three years of them, with little changes. They were always easy to get working and were reliable.
Yours should have the 17HP4, as the earlier models had the metal cone 17TP4, almost always bad. Chassis is transformerless, series string with a series-parallel arrangement and voltage doubler.
Probably 50 years since I worked on one. :scratch2:
