Philco 49-607 Filter Capacitor
#1

I'm replacing the filter capacitor in a Philco 49-607 by using discrete electrolytic capacitors of proper rating. Anybody have suggestions from your experience? I think I should tie wrap so they won't bounce around but I need ideas. Thanks, Ed

Ed,

this is a portable so I am not sure what space you got there; if possible we try using film caps instead of electrolytics.
Also, when choosing the first filter cap, if it is electrolytic (the one right after the rectifier - there may be a resistor in between, around 80-90 Ohms) make sure it is about double in its ripple current rating vs the current consumption.
I have a similar setup in my Zenith 7G605 and the current out of the rectiifier is about 75mA (could be a bit less in your case) so I chose the one with the Iripple about 150mA.

People who do not drink, do not smoke, do not eat red meat will one day feel really stupid lying there and dying from nothing.

Morzh,

Thanks for the information and suggestions. I'm only using electrolytic caps to replace the filter capacitors, 60-30-30-10 as I recall. The rest are film caps so not too crowded in the chassis. I'll check the resistor after rectifier/filter caps as you suggest. Good idea. Thanks.

Excellent work!   Icon_e_surprised

I re-stuffed the filter can on mine. Was pretty straight forward as long as the original can is intact. I've come across a few that were disintegrating and unusable.

Good luck!

That looks great! I may give it a try.
Thanks, Ed
