Philco 90 Lowboy
#1
Photo 

This Philco just came to me this morning.
I don't post very often, mostly lurking in the background reading all the posts and trying to learn as much as I can.  This is a mid production model 90, I am guessing, as it has the single 47 pentode output. I am not planning on working on this until this winter, sometime. (Have several others in the queue ahead of it.)
What should I be looking out for on this model? Is this one of the models that tend to have open RF or IF transformers?  It does have AF output, picking up strong stations when touching the grid of one of the 24s. (Not sure which one. The PO had been using it this way, against my advise not to use it until it had been properly gone thru.)  The speaker cone looks very brittle and bleached. Like it had been exposed to sun light. The cabinet finish has had something done to it, but it doesn't look too bad.

In the mean time, I will start gathering up capacitors and etc. to dig into it later. Thanks for any insights, advise, or help.

Chris,
