I put here a question that remained suspended in my last thread. I am going to replace the 3 can caps as mine were replaced with a rather random can cap by the previous owner, so anyone that has an HF81 with original can could please tell me if the positions of the 3 shapes (half-circle, square, trianle) are at least correctly oriented in mine (pic below) and which values correspond to each shape? i.e. is the half-circle the 20uf cap and the two other are the 40uf? Is half-circle the one above that shares the 22k 1W resistor with square on the right like in my pic? I don't want to put the 20 in a wrong place.
I am asking because there is a bit of confusion between sams and manual. Sams says C3a (half-round) is the 20uf cap:
while the Eico manual in parts list identify the can as C37 40/40/20 (that should logically be labelled A,B,C in this order but it doesn't specify it) and in its schematics it shows A as the first after the two single 30uf caps, in this case if A is the first one it should be 40uf and the last one (C) the 20uf. From the part list the resistors here are R60: 68K, R61: 22K, R62: 4.7K, R63: 350 ohm, C38 and C39 are two separate single 30uf caps.
All this is very confusing to me, any definitive clarification would be very welcome. Thank you
