The FM has been aligned, though all of the tubes are on the edge of or below minimum strength. There is a very knowledgeable person on the Scott forum who says the FM tubes need to be well above the minimum for the system to work quietly. I have NOS tubes coming. But for now, it is working. The converter from this same person arrived and I have it in use. The radio sounds great on FM. The converter allows me to tune the entire FM band, setting the desired frequency on the converter, then fine tuning with the Scott dial set at around 45 mHz. OR, I can set the frequency on the converter to one frequency and tune about a third of the FM band on the Scott tuner. This requires a calculation to know what frequency I am tuning in. It takes 3 such settings to tune the entire band (old band is 8 mHz wide and the current band is 20 mHz wide). Interestingly, because the converter local oscillator is above the desired frequency, you tune the Scott dial lower to tune in a higher frequency in the FM band. There is something satisfying about tuning the Scott dial all the way across rather than having it set at one frequency! A bit more knob twisting though. When I get the NOS tubes, I'll redo the entire FM alignment.
This complex radio is almost finished. I'll do a bit of work on cleaning up the cabinet but will not refinish it, It's pretty good. Then install the radio. That will help the bass response tremendously. I may even try to figure a way to add tweeters as that was an option back in in the day. Then it should match the Beam of Light Scott Philharmonic that I listen to regularly. Great radios.
