What Is The Difference Between Code 121 and 122?
#3

Thanks, Carl, I must've missed that. Edit: After reading the info I'm still stumped. I have an old chassis for the 42-1008 and the circuitry uses a 5Y4G rectifier, it's stamped code 122. This complete radio I recently accquired, less the turntable, is stamped code 121 on the chassis rear, and is also on the paper lable inside the cabinet. I haven't pulled the chassis and it's kind of hard to see the tube line-up on the paper lable, but, if I'm not mistaken the lable denotes a 5Y4G. I think I'm about due for a change in my spectacles. As I say it's kind of hard to see and the way I have it temporarily stored makes it very hard to tell as I can't move the radio enough to be able to see it. And if I'm not mistaken, when I looked at the recently accquired tech info and schematic for the model with code 121, it mentioned a 6X5 rectifier. I guess I'll have to probe a little more carefully, but thanks, guys, for your effort. UPDATE Tue. July 15: I still have the radio temporarily stored so I can't get at the chassis to pull the tubes. The only place a 6X5 rectifier is notated is on page 131 for the specifications, all other references including the schematic specify a 5Y4G, and parts changes seem restricted to the power transformer, a couple resistors, a condenser or two and the phono oscillator xfmr., which is of no consequence insofar as the record changer is absent. I've heard horror stories about certain 6X5 rectifier situations and my currently defunct RME 45 uses one of those. Shut up, Mikey, you're rambling. Icon_rolleyes
