Philco 38-690 with 37-690 trimmers??
#1

I almost have my 38-690 up and running. It had previously been aligned nicely, but I managed to get it a little off when I sprayed deoxit into the bandswitch contacts and unfortunately some of it found its way into the trimmers. I just noticed though, that this chassis has the full complement of trimmers and padders that you'd find in a 37-690 and they're located exactly where they'd be on a 37-690 chassis! There are no trimmers or adjustments where they are indicated to be on the 38-690 schematic. The chassis is clearly stamped as a 38-690 Code 121 and all the other components are where they should be. It's definitely not a 37-690 chassis. I'm not complaining since there are more adjustments on the 37-690 compared to the 38-690, but has anyone ever heard of such a thing??
