Having  problems  with a Model  70 (early) finding a schematic that identifies the value of those molded caps. Specificly Part # 4989C, 4989E, 3903L. The tube layout (single 47 output) says this is an early model but the serial number is 726678 - way over the 22000 that the Rider Manual lists for the early production.
