What is this wire?

Post by Krinkle »

What is the white wire attached to the ground lug along with the yellow striped green ground wire of the power transformer in this picture?

Do the original Partridge power transformers have an electrostatic shield/ground wire and is that was this is? I am thrown off because if they did, I would have expected the wire to be coming out of the secondary side of the xfrmr, and this one may be coming out of the primary, if it even is coming from the xfrmr. If not, it is a wire coming from somewhere else and I can't track it down in the pictures.

Anyone.......Bueller?

Judging from pics of my Hiwatts, I'd say that white wire is coming from the Power Transformer. It's either a shield or ground. In this shot of my SA212, you can see it's coming through the grommet under the PT:

Best leave it alone.

Is it a 50 or 100? If the former, that's likely the 50 watt HT secondary center-tap. See http://hiwatt.org/Layouts/DR504_Complete.pdf

It's from a DR103. It would be pretty disappointing if the original Partridges had an electrostatic shield and the Heyboer "Partridge-spec" didn't. I'm building this clone to run high gain pedals through a clean amp that is as quiet as possible, a la Gilmour. Here is a picture from Mark's site, looks suspiciously like an electrostatic shield.

I must be wrong, or there must have been a pretty good reason (which hopefully does not involve cost of manufacture), I just can't see Heyboer missing this, given what I've been hearing of their reputation.

Say it ain't so.
