Name That Transformer

OK, who can guess the identity of this poor flaming ember?
Rite clik no work-me move directory.
Also, can anyone think of why this might not be a good idea?

Me thinks it's a utc of some flavour...

Freed?

Which model?

Just kiddin. :grin:

Notice the drip pan for the wax.

Got the header loose.
Too much heat, maybe?
Smells like phenolic. Or Teen Spirit. Can you spell formaldahyde?

Nested lid to keep the wax from trouble during lid soldering:



Leads are numbered so I can blueprint this mo.
Notice that the lead numbers do not match the winder's scribbles.
Anybody guess what is going on?

Nice attention to detail, using the copper foil to get good contact for the core ground lead:

De lam. 3/8 by 3/4 fat stack...

Ready to unwire this guys central control panel!

Buss wire splices, bent over the heavy tape...

Heavy glass tape for good lead soldering platform, keeps the solder heat from damaging the coil...

Offset margins, don't ask me why.
Maybe for buss wire fold overs.

I can't unwind this coil with all those loose leads flappin round. They will eventiually tangle and break, making the expensive take-a-part a total waste of time. So the leads are mapped as to breakout location, if you miss one or two, you can guess which lead by process of elimination and other notes, as well as test data, including air inductance of de-lammed coil. I payed only 20 bucks for this privledge. Andy had an HS-66 with one of the notoriously brittle pins snapped. Do not drop a Triad with this type header!
Most expensive take-a-part? That would be the HA-100X during my early dissection years. The light gray vintage cost me $200 for the priviledge.

Lead mapping...then the scisors come out...

Wow. E shields on a 600:600 line in. I am impressed.
Those are usually reserved for input and some output applications.
A 1:1 ratio is usually pretty low capacitance, so the shields are curious to me.......Possibly more for CMNR. Or CSN&Y.
Notice a complete turn of the foil, which would be a shorted turn, is not permitted by way of the paper and tape.

Curious second layer.....partial turn layer, but still, you want a smooth base for future layers, dig?

OK, if that is the inner winding, we must be done. JLM says "Where's the beef?" :wink:

Alright, already.

Lams- 3/4 stack of (gulp) M6

Unloaded sec ringing test. 1 khz square wave...

Expanded. Weird charater on that one. Rather unique.

I found two more BH curves to check out. Lesser BH curves, wich are just BH curves drawn at less levels of saturation.
And high frequency BH curves, which I have not been able to see due to low levels coming out of the signal generator. Maybe I can amplify the generator for those types.

Here are some lesser BH's, then the final BH....

OK, here's the cheat sheet.
Let me know if you want more details.
The HS-56 is used in the Pultec eq's.

Just a sec-pri-pri-sec job with 2 e shields between the two middle windings and their neighbors.

The only difference between the HS-66 and the HS-56 is the extra shield can, I do believe.
No, I am not going to take apart my HS-56 to make sure!
But the inductance and dcr seem about the same.

Damn CJ....

You are so wonderfully SICK!!!! :green:

GARY

OK, from the first pic I knew it was a TRIAD.

hi CJ

i want to ask about the diameters of your clone of triad hs-55/66 in (mm) and any details about transformer making

thank you
