  • Annotazioni
  • The Philco model 60 series included nine versions over four years, all using similar 5-tube chassis.

    There were six versions of the 60B cathedral. Version 1 (1933) had the simpler flat-front version of the classic cathedral cabinet with spade-shaped speaker grill which was used on many 1933 models. Version 2 (1934) had three vertical bars through the center of the center of the speaker grill, with short downward curving arcs added at the bottom of the speaker. Versions 3 and 4 (1934-35) had similar cabinets with an oval shaped speaker grill with a stair-step pattern; version 3 had a metal escutcheon with "Philco" stamped into the metal, and version 4 had a black bakelite escutcheon with a "Philco" decal on the center of the wooden front. Version 5 (1935) had the same cabinet as versions 3 and 4, but with a larger black bakelite escutcheon and a new dial scale design. Version 6 (1936) was a new style cabinet with a continuous arch from the base of the cabinet.

    Model 60MB (1934) was a tombstone with a modern design, having three downward facing arcs through the speaker grill and hexagonal knobs.

    Model 60L (1933-35) was an ornate lowboy with four vertical bars through the speaker grill and other embellishment.

    Model 60F (1935-36) was a floor-type console with a tulip-shaped speaker grill.

    The general spirit of the model 60 series continued into 1937 and 1938 with models 37-60 and 38-60, which were also 5-tube 2-band radios.

I've just restored a Philco 60B and put it to a long time working test.
After some time of normal operation, it suddenly stopped and presented a frying noise coming from the transformer.
I turned it off and made an inspection looking for a possible short on the B + circuits.
Everything was as it should be.
Removing the 80 tube, the noise stops.
Disconnecting the B+ power line to the rest of the circuit and puting the 80 tube in it's place the frying noise come back.
I measured all AC voltages of the transformer without the 80, and all are ok.
All the Ohmic resistances of the windings are ok too.
I also measured the insulation between the windings and did not notice anything abnormal.
Thus I came to the conclusion that there is a sparking between the 350 and 4.8 windings. The sparking occurs only when the 80 is in place.


Bad news for me ... The power transformer must be redone.

Cheers,

Meyer
