Philco 112 Lowboy restoration (caution, lots of images)
#14

So what ever happened with this 112 restoration? I just spent the weekend on a early 112 chassis with pretty much the same layout. Got the set with no tubes and a friend did a beautiful job on the cabinet so now it is my turn to get the chassis ready.

Finally found a Hickok 530-B Tube tester up on my shelf that helped validate some tubes for it, and it seemed like it powered up OK with good audio and IF, but it took a while for me to pay proper attention to the tube basing and lack of plate voltage at the RF Amp. Traced it to the coil in the plate circuit was open and was able to find the break near the first turn and solder in a 'patch.'

Voila, we have a radio, just a little intermittently low on sensitivity and gain intermittently, but able to get stations all over the western US when it is working right :-). Probably still a bad cap in a block somewhere, as I didn't touch any of those or the condenser block. This set has great B+ and no hum.
