Found some additional info on the WWW and proceeded to rebuild all the Philco Block Condensers and replacing out of tolerance resistors as I went along. Quite a lot of R's had drifted high well over 20-30% and some were double their value.
The radio is now receiving stations on the broadcast band after doing a quick IF alignment but not very loud at full volume. So I may still have an issue somewhere.

The RF alignment requires tweaking a hexagon nut which is down below the surface of the can.
Just wondering if it's OK to use an appropriately sizes tube spanner on these nuts?

The shadow meter starts narrow and widens as the set warm up but it will not open and close when changing stations. Coil is OK and vane moves freely. Plenty of Web info suggesting that it may be related to signal strength, weak tubes or improper alignment. Have decided to leave it alone till I work out how to do the RF alignment.

Cheers
Rob
