Hi folks,

I have exhausted all possible avenues in my bid to answer a couple of questions I have on the DC30 clone I'm building. I hope the the good folks here could put my mind at ease!

I'm using Ceri@tone's layout but sourced all the parts, etc myself. http://Ceri@tone.com/images/layoutPic/m ... iatone.jpg

I'm using Hammond trannies. They are the Vox vintage replacement set. I'm fine with the PT wiring but have a couple of questions about the OT. On the Ceri@tone layout the OT primary is labelled P - CT - P. Here's the Hammond data sheet for the OT which include the wiring diagram. http://www.hammondmfg.com/pdf/EDB1750V.pdf

The primary has Yellow - Red - White wires. I'm guessing the CT is the red wire but am unsure where to connect the other two primary wires. The layout is labelled Q and S which are connections to pin 7 of two of the power valves.

I'm not sure if it matters which way round the yellow and white wires go. Surely the voltages present at pin 7 on the valves is the same does it shouldn't matter??? I'm stuck!

Any help would be greatly appreciated.

Thanks,
Gary

I searched the forums for "primary" & found this, among others:

It probably doesn't matter, but you may find one way causes more "squeal" that the other.

I built a Ceri@tone Stray Cat a while back (uses their DC30 clone iron) and I would expect this one is probably wired the same way. If that's the case I expect the white primary wire would equate to "Q" & the yellow to "S" on Nik's layout diagram.

If you find the amp squeals more than you'd like, try swapping them. You won't hurt anything if you reverse them (other than maybe your ears form the squealing).
