[Amps] Help Alpha 77-DX

[Dan]

Terry: The schematic for my 77DX shows separate, additional loading , fixed
caps on A and B. One is a parallel pair of 100pf caps and the other is a
500pf cap. The description re RF amp says nothing about the additional
switched in caps. My s.n. is 3280  73, Dan, N5AR
