I cannot recall the exact model of this Silvertone but if I find out I
will post it. It needed new capacitors, plus some wiring repairs. The
6F5 tube and tuning eye also needed to be replaced, and we installed a
new audio output transformer salvaged from a Silvertone stereo receiver
chassis, plus a new filter choke and permanent magnet speaker. Please
click the pictures for larger views.
One problem was that an excessive amount of solder was used on a
previous repair job, shorting out the tuning capacitor. We used a
solder wick to remove the old stuff and re-did the wiring.

speaker.

Speaker, output transformer, and filter choke installed in cabinet. We
were able to salvage a good output transformer from a junked Silvertone
tube stereo receiver.
New tuning eye tube installed.
Chassis re-installed in cabinet.
Finished Silvertone. The owners are going to finish the cabinet and
grille cloth repairs.
