PWR XFMR wiring

[skipper]

Hi All,

I am rebuilding my Simple SE amp and I have a PWR XFMER question. I am using the Edcor PWR035 XFMR and thought I had taken enough pictures of how I wired it before taking it apart but apperentlly not From the Edcor schematics, it looks like the black and black/white wires are for the 115V power input and return. The two green cables I am not sure of. They do not show up on the schematic and they do not seem to be ground cables? If I ohm them to the chassis ground, it is an open circuit. Should these green wires be grounded?

Thanks!

Electrostatic shield? Are all of the other wires in the diagram accounted for?

No they are not. From the diagram, the ceter tap wire for the 370V and the 6.3V I have taped up since they are not used, these are shown in the diagram.
Besides the two green wires there are also a pair of grey wires that are not shown in the diagram. I have also taped these up since I do not know where they go?

I'd contact Edcor directly. I e-mailed them yesterday morning with a question on custom OPT winding, and got a reply back within about 10 minutes.

What I meant was, are there any wires shown in the diagram that are physically missing?

Guys,

Thanks for the replies, sorry for my late reply. After checking my purchase order, I realized that I actually ordered the 059 and not the 035. I did ask about the 50V gray wires as to what they would power but did not get a response back.
Thanks again!

That is a 50V@50mA winding that would typically be used for a negative bias supply. Often these are taps off of the main high voltage secondary, but here they have made it a separate winding (which is nice). You don't need it at all for the SSE.
