Hello everyone. I've finally got around to building my Sa3a that's been sitting in a box for the better part of a decade. I've got some Sowter transformers for this, but i'm left guessing as what the correct wiring would be for the interstage transformer. Sowters site lists the transformer as
blue - common
pink - 1:
red - :10
but the original schematic and this board it's listed as
5
2.5
.31
I'm guessing 5 is also common (blue) from looking at the original schematic and beep testing to ground, which could mean that 2.5 is pink and .31 is red, but unsure?? Or maybe they've sold me the wrong transformer?? Shrug!
I messured impedance
blue to red 512.96ohm
blue to pink 6.7ohm
pink to red 507.35ohm
Sorry if there's an obvious answer here, I'm terrible at math
Thanks for any help you have here.
