philco 40-150 - pete g - 12-19-2019
hi folks, I have a question for the forum. can the above model be made to work without the power transformer? if so, how would one go about it?
RE: philco 40-150 - Phlogiston - 12-19-2019
In an absolute sense - yes. But you are still going to need a power supply, probably using a transformer.
In a practical sense - no.
I take it that the original trans. is no good?
RE: philco 40-150 - pete g - 12-19-2019
yes, the orig transformer was missing from the radio.

I only took a quick look at Rider's, but, it appears that trans was used on several models. You might want to put up a WTB ad here, or there is a guy selling transformers on E-Pay - for too much $.
ARS (Antique Radio Supply) sells new transformers which are not exact replacements but often you can find an acceptable replacement. These too are not cheap.

o.k., i guess its going back on the shelf. i really don't want to put a lot of money in this project. thanks for your response.

Best keep an eye out for a used one.
Other radios that use the same or similar tube combinations can also be a source.
RE: philco 40-150 - pete g - 12-19-2019
will do.

There is a classified listing on ARF https://antiqueradios.com/forums/viewtopic.php?f=15&t=369280 for transformer for a 40-185, not the same part number but, probably close enough. the 40-185 has one more tube.
