OK, back to Dan's original question. The Philco 20 is easy to work on. There is plenty of room under the chassis, easy to get to all parts. As with all the older Philcos, there are a few bakelite capacitor blocks. Plan on all the resistors being high in value. New dog bone resistors are available. 
If there is a problem with the interstage transformer, there are new replacements. The speaker may be good, if not, they can be repaired or good ones show up eBay fairly often.
