[ARC5] ARC5 Receiver Power Supply

[Phillip Carpenter]

Mel's,

My bad, the article is in Volume 2 on page 59.

Also in that article all tubes have been changed to 6v heaters so the eye tube was a 6E5.

Your going to have to determine if the receiver is still using 12v tubes or has been converted to 6v tubes ( just look at the tube numbers). Since the eye tube socket is an octal it is likely a 1629 which uses an octal socket. The 6E5 uses a large six pin socket though there are British 6E5GT/CV1906 eye tubes that are octal based.

There is an octal socket and a cable with an RCA connector on the end. He remembers that the socket was for a magic eye tube and the RCA connector would have connected somewhere in the receiver. But he cannot remember the details or exactly what eye tube type was used or what the function was.
