Crosley 6H2 - AzSteve - 10-25-2024

Thanks to all who have helped me W/ restoration of this beast! I've looked at a couple schematics (W/ dismay) & am astonished at the lack of info shown. Thankfully I've got my trusty RCA RC 16 (as well as GE & Tung-Sol references) to help me figure out which pin is which...
I would appreciate suggestions as to coming up W/ a suitable Screen Voltage divider. I imagine that a series of Ohmite "Brown Devils" would suffice? Maybe an Ohmite "Dividohm" would work, assuming that I could access the parts from my 1949 Allied Radio catalog (just being sarcastic)…

Hi Steve. If your 6H2 is the same as mine you'll find a few issues with the wiring when compared to the schematic. I found that my 6H2 was in some ways a combination of the 6H2 schematic and also the 6H3. I'll try to highlight of a few of the issues you may or may not come across.

Attached is a marked up schematic of the 6H2 showing the pin numbers and other notes that I made during my restoration. You will see on that schematic in error, the #42 output tube screen on pin 3 and filament on pin 1 are both connected to ground. Your radio is not likely wired according to the schematic in this manner as it obviously wouldn't operate. The screen on this tube should be connected to pin 4 on the rectifier and operate at about 250V. This is above the plate voltage of about 240V as it passes through the output transformer. The screen is not directly part of the divider circuit that you are referring to.

The Candohm resistor can be difficult to work on. It is represented on the schematic as resistor 56 and 57. I replaced it with two chassis mount power resistors (see photo).

A few other differences that I found on my radio (you may not have these on yours). Resistor #79 on the 6H3 schematic was installed between 6A7 pin 2 and transformer #5 primary lead #2 as shown on my marked up schematic.

R49 on 6H3 installed between 6D6 pin 5 and ground

C36 on 6H3 installed between R58 and ground.

I'll PM you a link to all of my before and after photos that may also assist you.
