Someone gave me a working Marantz Model 22 in a walnut cabinet. It had bee stored for awhile and I've been cleaning and polishing, knob by knob. Amazingly, all the bulbs work except for one meter. The receiver works well. The tuning seems to be spot on for FM. Haven't tested AM yet. One problem. The two tuning capacitors appear to be out of sync. The tuning dial only goes to the left as far as 92.0 Mhz. Of the two tuning capacitors, the upper small four gang unit is as far down as it can go. The larger three gang capacitor still has some turning space left. Can I just disconnect the gears and sync the two. It couldn't be that easy. I keep hearing a voice in my head saying "do not try this at home. This is only for trained professionals". Any comments?
