OPT connections with SSE

[Hey19]

Newb question: Building my first amp using Edcor cxse25-8-5k opt's. George's wiring diagrams show red, dark blue and light blue wires on one side and black and green on the other. My edcors are (respectively) blue, white w blue, and red on one side and yellow and white on other.
Apologies if this was addressed on the Tubelab site or in the archives, but have searched with no luck- Thanks.

Why not do a Google search for Edcor cxse25-8-5k? It will take you to a schematic for the output transformer.

My question was that I was hoping someone who'd used decor opt's recently (I've read that their lead colors can vary) could enlighten me on how they correspond to George's opt lead colors.
Thanks

Colors

You should have gotten a card from Edcor with your OPT's that show what leads are what color... It can also be found on Edcor's website for your OPT, the colors there match what you indicate you have...

Here ya go:

Inputs
Blue wire = Plate
blue-white = UL tap
red = B+

output side
White = common (negative speaker terminal (not the ground tab)
Yellow = 8 Ohms (positive speaker terminal)

I don't remember if my positive output to speaker was yellow or not but that should be fairly easy to sort out.

ask questions - easier than fixing a screw up

Cheers,
Bob

Maybe this will help.....

An externally hosted image should be here but it was not working when we last tested it.

The corresponding plate (anode) connection on the board is labelled O1, where the T3-Pri, respectively the T2-Pri connectors are marked. O2 is the UL and O3 is B+.

Hope this additional help is useful.
