Started digging into my recent EAC purchase, and began with recapping
the IF deck. The installed caps all look original, but there were a
mixture of the the hermetic paper-in-oil West-Caps, one Sprague Vitamin
Q, 2 of the infamous Brown Beauties, and 2 different styles (round and
oval cross section) of CDE film caps. Was it usual for a wide variety of
different capacitor types to make it into one module, or could this be a
result of the lateness of the production, and using up whatever parts
were left in the bins? There were 0.1 uF caps from 4 different
manufacturers in this thing!
All being replaced with 630V rated mylar film caps, including the 2 uF
AGC cap, which is being stuffed inside the original can.
