[Marsupial]

Warren, I too have an 47-1230 - this is a beast to recap. It will take time, but the radio is worth it.

When I got mine, I bought the service manual for it (got lucky and found it on ebay for next to nothing) which I scanned. Very useful.

There are things that even the official Philco documentation don't cover, such as the 3-legged feedtrough capacitor seen here:

so don't be shy to ask any questions, people here should be able to help.

Also, please post pictures of your progress.
