Thanks David - that's great
Thanks again Arran.
Indeed during the move, the chassis was not bolted down (I was not around to supervise any of this). The set was wrapped in cardboard and plastic film, but things were quite out of place when I removed the "packaging". My wife wonders if they were removed for safekeeping and misplaced... Anyway, I have ordered replacements.
More tinkering today (and I was really intending to complete the back for the Philco). I sorted the dial mechanism - removed gunge off the cord with parts cleaner, lubricated the pulley system very lightly and it is now all working well. Ditto the waveband and tone indicators. I also started to look at what could be used to remove a yellow corrosion/deposit from the chassis. A mix of vinegar and denatured alcohol seems to work quite well for this, and I'm working my way slowly along the metalwork.
Electrically things are in OK shape - the field coil and output transformer show continuity and correct resistance. However I'm still shaking my head at the lacklustre restoration effort. A quick appraisal so far shows:
Many caps not changed
Frayed wire all over the place
Random types of new caps tacked in place, "j hooked" to the old component leads, and otherwise bodged in.
Electrolytic caps not replaced at all! It is still relying on the old 4 section can. No chance this was restuffed as the solder joints appear to be factory age, unlike the replaced parts.
I have not decided whether to try and replace the multi section can with something similar, wire new caps beneath the chassis, or restuff the original can.
At this point, I need to step back, take a deep breath, and then write a list of all the areas wanting attention.
But first, the Philco needs the last touches.
Cheers
Ed

I don't hold with furniture that talks.
