As a TMCC newbie, I’d like to know what electronics are inside a vintage MPC-era F-3 ABA that’s been converted to: (1) a TMCC twin- motor A unit; (2) a non-powered, sound-equipped A unit; and, (3) a bone stock dummy B unit. LIONEL Milwaukee Road 6-8555, -8557, and -8575. This was a recent estate sale purchase.
I’ll start with the electronics in the non-powered A unit and its very neat appearing speaker installation and antenna. Also, though not clearly photographed, is a 9-volt battery connection visible on the right side edge of the second photograph.
As I said, I’m a TMCC newbie and don’t know why there is provision for a battery. Do I need to install one for this to operate properly? I’ll be taking it to the club Saturday for its first run with me as owner. If I need a battery, I’ll need to buy one.
Also, there is what appears to be a volume control know that was loose at the rear of the unit. I regret not photographing it.
Thanks in advance for your replies.
I'll post photos of the twin-motored A unit Saturday (It's at the club). Its TMCC conversion works perfectly. I just don't know what electronics are inside it.
