Good morning,
I've recently ordered the better material from Mr. Schwark for this set because all I have paperwork for is the code 121 chassis and the tube lineup is different then my code 125. 121 schematic shows a 35Z5 rectifier and a 50L6 output and my 125 has a 35Y4 and 50B5 respectively. This is no problem because with socket changes either will work but I don't want to change the original configuration of the set.
All I have to go by at this time is a 35Z5 and between pins 2 and 3 on the tube itself I read 7.8 ohms. Because of the similar electrical characteristics to the 35Y4 I'm guessing that between pins 1 and 4 of this tube would be somewhat similar. Is this true? Also, do pins 2 and 4 on the 35Y4 socket need to be jumpered together? I'm looking at a 46-200 schematic because it has a similar rectifier/dial lamp circuit as my 46-250 and it appears so. My lamp is connected to pins 1 and 2 of the 35Y4 socket but I don't see where pin 4 is connected to the lamp at all.
Thanks,
Johnny
