Very good news indeed!
Yes, and he also has the winding info for the Triad HS-50,
signal output for the Fairchild 670. :grin:

Oops! HS-52 goes in the 670 (has to be p-p)
But he has that info too!

Trade you for the control amp input winding info!
Darn, a HS-3 went for $100 on evil bay the other day. Same as HS-14, control input, just mu can differences. Could have dissected that to complet the xfmr 670 info.

Can someone point out the functional difference (if any) between the Triad HS-56 and HS-56V?
I have both an HS-66 and an HS-56V. Looking at a photo of an HS-56 (no V suffix) on eBay, I notice the only difference in specification is in the working voltage. The HS-56 (and -66) specify 175V, whereas the 56V specifies -175V.
My plan was to use the HS-56V as a Pultec input transformer. Does the V suffix denote negative voltage is required? CJ thought they were the same when I spoke with him, but I can't find any catalog page describing the 56V.
Here's some photos:
Triad HS-56 (from the Web) (Wrkng Voltage = 175V)
Triad HS-56V (Wrkng. Voltage -175V)
Triad HS-66 (Wrkng. Voltage = 175V)
Any help you can give is most appreciated, and I think will benefit the group as HS-56Vs seem to be on eBay a lot these days.

I'm building a tube Pultec (EQP-1A), which uses an HS-56 according to page 7 of the manual (http://www.purpleaudio.com/pdflib/PultecEQP.pdf).
My hunch and CJs thought was that the HS-56V was interchangeable.

The should be the same. The V is good for 70,000 feet, so if you are installing an 8 trak studio with Pultec outboards into in a Lear Jet, then your all set.
Wait a minute, don't they pressurize cabins nowdays?
But wait, I am redeemed, .....the Pultec gets kept in the cargo holdt for zero degrees and low xfmr dcr.

CJ, good eye on the max altitude difference. Maybe I'm hallucinating the +/- voltage thing (the print is very small on the HS-56V and tough to discriminate b/w = 175 and -175).
