Philco 40-125

Hi and welcome,
As Bob said 35A5 and 35L6 are electrically the same but require different sockets, one is a octal and the other is a loctal. Neither of these tubes are any thing like the 7C7. So to answer your question No. When you get a minute snap a few pics 1 of the top and one of the bottom. This may shed some light on what you have.

It also has a electrolytic connected to the 8th pin going to the on/off switch. Well if you are referring to the 35L6 socket it would be the cathode bypass capacitor 20mf @25v is fine. Value isn't very critical. Pin 8 on any of the other tubes (loctals) is connected the filament which has ac voltage on, electrolytics don't like ac at all.

For better service info always rely on Philco service bulletins. Look here:  http://www.audiophool.com/Philco.html  Just click on your model number.

Sorry for the duplicate info I've been spraying lacquer this evening.

figure out what all those squiggly meant.

Now I think I've got it!
