Well, I'm off and running on another radio project. This time, I am going to recap, rewire and recarb a Philco-Tropic 42-730EZ.

Like most of my Tropic sets, this one has been sitting around for a few years patiently waiting for me to get around to doing something with it.

Here's how the chassis looks outside of the cabinet:

It uses seven tubes and has five tuning bands - the standard AM band (540 to 1720 kc); SW from 2.3 to 7.5 and 7 to 22 mc; a fourth band covering the 31 and 25 meter bands (9.4 to 12 mc), and a fifth band covering the 19 and 16 meter bands (15 to 18 mc).

As usual, I started working on it before I remembered to take a "before" under-chassis shot.

At this point, I have replaced three paper capacitors and four resistors, and also replaced a few rubber-covered wires. Can you tell which capacitors have been replaced?

You can follow along by looking at the schematic here (warning for those of you with slow connections: this file is 633K in size!).
