Help finding tube
#1

Hi All,

I'm trying to help out a friend who's trying to fix a Philco radio for his folks. He tells me the model is a 41-258 and the tube he needs is a 35ZGT.

I've had almost zero luck googling that number, the closest I've found was a 35Z5GT but I don't know if that's a similar tube.

Don't know where else to look so I thought I'd try posting here to see if the experts can help me find the right tube.

Thanks in advance.

Jim

Hello Jim. I looked at the schematic for your friends Philco mod 41-258. It does have a 35Z5 GT (rectifier tube). There is no such tube as a 35ZGT. I bet one of the numbers rubbed off the old tube and that caused the confusion. The 35Z5 GT tubes are readily available as many radios use the same tube as the rectifier. You can get one from Antique Electronic Supply (http://www.tubesandmore.com) If your friend needs a copy of a free online schematic, he can download and print one at (http://www.nostalgiaair.org/) . Once at the website, click on schematics, scroll down to Philco made in USA, click on Philco, then scroll down to model 41-258 (code 121) and print it out at 100% on his computer printer.

Best of luck to you guys on the Philco 41-258!! If the radio hasnt had new capacitors installed yet, it would be advisable to replace the electrolytic-filter capacitors before attempting to power-up the radio!! A "full recapping" would be best for overall original performance, and it really doesnt take that much time or cost-expense either! There is plenty of info avail here if you need it!! Just ask, and your questions will be answered to the best of knowledge avail here!! Randal ( TxRocker)
