which tubes are correct for my model 52B?
#1

I bought a model 52B from a local collector.  Cabinet is near perfect and the chassis is untouched.  I've never worked on a radio this old, and joined the Phorum.  My radio has a sticker on the back that identifies it as a Chassis Type 52.

My first question involves the tube lineup for the RF/IF/Det/Audio/Rectifier functions.


The set  came with 24 / 39(44) / 24 / 47 / 80

The schematic on the Phorum lists:  24 / 35 / 24 / 47 / 80

Inside, on the tube shield is a sticker that says "Philco Model 224" and it has a beautiful 3D drawing of the chassis.  It lists 36 / 44 / 36 / 42 / 80

I can post pictures if this helps, thanks for any info!!
