At a garage sale I found a Philips AM-SW-Phonograph
Model Number 53-1750. It has a 60 watt amp.

The cabinet is solid mahogany and messures
26"H x 26"D x 18"W(30"W with the wings extended
The nobs are on the front and station locator
is on the top.

The AM works but has a hum.
The phono works but needs new rubber mounts.
Shortwave doesn't work.

I'd like to find schematics, a tube source for 50Y7GT
tube and repair sources. And year of manufacture.
The serial number is 0211062301

It makes a great end table but I'd like to get
it working right.

Thanks in advance for your help.

Hi Nick

Your radio was made in 1953. With a lot of the Philco's the first 2 numbers of the model number is the year manufactured.

Sam's Index lists your radio as being in #203-7. Most libraries can order the Sam's Photofact which has the schematic.

Antique Electronic Supply has the 50Y7GT tubes and lists them for $3.50.

Hum in your radio is generally caused by bad filter caps. These caps dry out over time, loosing capacity, and allowing hum.

use 50L6 instead of 35L6, 25Z6 instead of 50Y7, and use shunt resistor across entire filament string except for rectifier.

try Antique Electronics Supply for 50Y7 tube.
