This is another radio that belongs to Juvenal.
Basically, I retored all Philco bakelite block condensers (Fig. 1 to 4) and the box condenser (Fig. 5). Replaced electrolytics, output transformer (Fig. 8), and out of specification resistors, and rewound the oscillator coil (Fig. 6).


Fig. 1 - A Philco Block Condenser

Fig. 2 - Melting all old tar potting compound with a hot gun to release condensers. Do not overheat the bakelite block, otherwise it will get bubbles.

Fig. 3 - To remove traces of tar use thinner and a rag. Bakelite block then ready to receive new condensers.

Fig. 4 - New condensers inside the bakelite case.

Fig. 5 - Box condenser: old (tar) and new (yellow).

Fig. 6 - Oscillator coil rewound.

Fig. 7 - Philco 89 front, missing original knobs. Any available?

Fig. 8 - Philco 89 back. Note the new output transformer.
