philco 90 ecap question
#5

No, no, no...

Look here:

http://www.philcoradio.com/tech/images/90b.jpg

Positive of (56) to the junction of one leg of the 80 filament and the input lead of choke (55).

Negative of (56) to B- which is the high voltage secondary center tap, lead 12, and its junction with the bias or B-C resistor ( 58 ), terminal 1.

Now:

Positive of the output electrolytic (57) to the junction of the output lead of choke (55) and the speaker socket as indicated on the schematic.

Negative of (57) to chassis ground.

If you cannot read schematics or are having difficulty, STOP and learn to read schematics before proceeding. If you do not know what you are doing, you may fry a power transformer or other component, or worse yet, fry yourself...and we do not want that to happen.
