Hello every one, A frind of mine has given me a Philco model 89 to fix. He says it worked a few years ago, then when he recently plugged it in, in started to smell. When I got it i found the remenents of a mouse shelter, oddly the mouse did not harm the radio in any way. I also found a pool of a dark wax or tar on the bottom of the cabinet (under the chassis) , and under a board inside the chassis near the transformer, and the chassis is discolored with a brown and black coating. It looks like something exploded but the transformer is O.K.

Also the type 33 oscilater has been replaced by a 6a7, in which all the pins are used. And there are 2 50's drycell caps 1,two part 100mfd cap and a single cell cap with no markings and no other Filter caps In the chassis.

Anyone have any idea where to start?

The original osccilater was a 36 not a 33, and the schematic shows a 3 gang variable and this radio has a 2 gang.

Hi Ian

The radio is another model. How many tubes? One of the most popular models is 610. Check the schematic under resources, above.

Hope it helps

Hi

Could someone have replaced the chassis? 6 tube version of the 610 is 620 but it uses a 3 section tuner. Can't be that one.

The 89 did use a 77 or 36 for osc but not 6A7. Was the socket replaced? How about the tuner?

I don't think a complete replacement, because the cabinet is discolerd where the chassis was, and the tuner is original, but the 6a7 socket was replaced. This still dosent explain the 2 100mfd caps, These arent found in radios with a transformer, it would probably blow it right?

Here are some pictures of the chassis.

Hi Ian

Is someone changed the original tube to a 6A7 your radio won't follow any schematic. Use parts from a Model 89 and some from 610 or 620 schematic.

A radio can still operate with 100 mf filter caps as long as voltage rating is high enough. 100 mf will cause extra surge current through your 80 rectifier and may cause heating of the power transformer. Best to use 10 mf @ 450 volts off of an 80 tube. Lower values extent the life of a rectifier tube but may allow some hum.

The model is a model 45. It looks like philco made too many 89L cabinets and started putting 45 chasiss's into them near the end. the 100mfd capacitors are really 10.0 Mfd and the 6a7 is original. Is'nt philco documentation wonderful.

there are 2 89 mod. one uses 1-36 2-39/44-1-42-1-75 1-80 and the other uses 2-39/44 1-42 1-75 1-77 1-80 both are 6 tube.
