I am having a heck of a time doing the alignment on the AM band. I can't seem to dial in the 1500 KC oscillator. I can hear the tone on multiple places around 1500 KC. Closest I can get is 1520 KC. I am adjusting 42, 24 and 6. 24 and 7 seem to peak up. Adjustment of 42 comes in a various spots on the compensator. The 580 adjustment is spot on although station 740 comes in best at 750. Station 1550 comes in best at 1560. I expect better with this radio. Is this radio really that hard to dial in. I had a very hard time with the SW bands too but got them good enough.
Mag tuning is off and all tube shields are in place as well as the bottom plate. I am using a frequency counter along with my signal generator.
Maybe I should have changed those mica caps in the RF section???
