Just received a 51-932 yesterday and it has a code 122 chassis. The schematic I have calls out for a 35Z5 rectifier and 35L6 output. Apparently the code 122 has a 35Y4 rectifier and 50A5 output and is wired as such. There is still a 100 ohm resistor (R5) in the heater string wired into the chassis which I assume was to drop some of the line voltage with the 35L6 version. Being that the output is now a 50A5 is that resistor really still necessary? Thanks in advance!

Just to make sure, you chose either 4 ohm into 5K or into 10K? (blk-org or blk-grn)morzh — 06:23 PM

Thanks for the reply. Unfortunately the radio was removed before bidding was over so I didn't get a chance to bid.dconant — 04:10 PM
