Powering a King 10K1 Neutrodyne

Posted by Craig Roberts on 04/02/2009 12:17

One more coat of clear lacquer and a light buffing will finish my complete(and ridicuously expensive, thanks the price of known-good O1A tubes) restoration of a beautiful Silvertone-branded King 10K1 Neutrodyne receiver.

Okay, I do have to finish building my battery eliminator power supply, but that should be the work of a couple of hours at most. At any rate, I need a question answered before I power this thing up. We have the expected "A" battery connectors, plus 90V and 45V binding posts AND a mysterious (to me) pair of posts for + and - 4.5V. These are jumpered together with cotton covered wire that looks original. What were these for?
