Philco 112 Lowboy restoration (caution, lots of images)
#1

Hello,

I'm restoring my first radio, a philco 112 lowboy.

The radio was found on craigslist for $50. To my untrained eye it looks mostly unmolested.

I have done a bit of work on the cabinet and it now looks like this:

Next up is a new coat of lacquer.

I am now trying to wrap my head around tube electronics The top of the chassis looks like this:

And the bottom like this:

As far as I can tell everything is original. I have avoided the urge to plug it in and have now removed enough components from it that doing so wouldn't get me anywhere anyway. Icon_smile

I've ordered a bunch of capacitors and resistors from JustRadios which will hopefully show up soon so I can move on with the soldering.

This model has a large very annoying 'condenser block' thing which seems to contain all the larger capacitors.

I wasn't able to get the innards out using a heat gun, so I moved up to heating the sides with a propane blow torch. That worked quite well and now i have the case free:

The heat did beat up the paint a little, so I plan to respray it.

In case anyone has ever wondered, the innards look like this:

and one of the capacitors unrolled like this:

Am I correct in thinking that none of these capacitors are electrolytics? They all seem to be paper.

I am replacing them all with film capacitors.

There is one coil which looks different from the others:

That is the best picture I could get of it. I understand these can corrode? is that what the little dots are? I haven't tested any of them for openness yet.

Anyhow I hope all my rambling is interesting to someone out there...
