Philco 38-7CS...I think
#4

Hi Arran,

Thanks for the informative post. I am not familiar with capacitive ballast but I am figuring on 125AC from the wall yields a cap that needs to drop 32 volts @ 300 mA. I get 106 ohms which means an ~ 25 uF non polarized AC cap or a DC cap of at least 400V. Did I do that right? Might be a moot point.

Hiya Kirk from a fellow Long Islander way East in Suffolk. You have amazed me with your cabinet restorations from kindling. Let me know if you take on projects for others - paying of course. PM.

Rich
