Well, I purchased the 32-8196 input transformer from "Playthings of the past". To review (or read earlier posts in this thread), I'm going to have to try and substitute this transformer for the one that is normally used in this radio for the phono input since the exact one is not availble at a reasonalbe cost.
The problem I'm seeing is this. This 32-8196 has one RCA jack on it's top plus a 4 pin type connector as well. The resistance read across the RCA connector is only about 1/2 ohm or so. The resistance across one pair of the 4 pin connector is about 105 ohms and the other pair is about 1.6k ohms.
I'm not sure what the meaning of these readings is. I thought there was going to be a primary and a secondary but seems we have three isolated windings. There is infinite resistance from any winding to any other so can't be any type of autotransformer either. Then I also got this pigtail old cable to connect to the transformer. It has a 4 pin plug that fits the connector on the transformer and two sheilded leads coming out of it with bare wire ends. Each pair of wires has a copper braid wire around them.
I assume the RCA connector (winding) from the transformer would connect to the RCA connector on the terminal strip on the back of the cabinet which then goes to the tonearm "cartridge" (BOL output). But... what is to be done with the other two pairs of lead wires from the transformer? On the 41-608 diagram the common or shield side of the autotransformer is at ground and the other lead goes to capacitor #51 (.006) which is on the grid of the preamp tube.
Does anyone have a diagram of the model that uses the 32-8196 transformer to identify what is done with that 4 lead set of wires from the transformer?
Any help will be appreciated !
