Can I use this transformer with one them T12 solder control kits?

I have an old OK Industries station that's missing the 6 din pin handle. They are hard to find, obsolete, and cost more than an entire newer station. I tried to retro fit a newer HAKKO FX-888 6 pin din handle (which really only uses 5 pins) and that failed. The OK Industries has 6 pin and uses 6 wires. One with 16v AC and another with 33v AC. Both will heat the iron just fine and you can measure the resistance with a multi-meter going up as it heats up but appears the controller will not control the temp. Its all or none. Plus I ain't even sure I am hooking it up right. Or controller broke? I gave up. Not smart enough to figure it out.

Anyways, I was wondering if it was possible to just hook a bridge rectifier to one the 16v AC lines to cut it down to 15v DC and use one them T12 kit/handles in it. The T12 controller should fit in the case just fine. (vertical / sideways) but a simple install where the original controller was at.

Can I / do I just go straight from the bridge rectifier to the T12 power in? Do I need anything else added? The transformer says 14v 80VA  is that enough power? too much?

And I tried to make the original controller work - https://www.eevblog.com/forum/beginners/help-with-an-ok-industries-iron-wiring-please/

The OKI SA-1000 power transformer A41-80-28A33 is made by Pulse 28VCT 2.8A or 14VAC 5.6A 80VA.
I would expect 22-19VDC after a fullwave CT (2-diode) rectifier and filter cap. You are getting more than spec because there is no load on the transformer and your mains voltage may be high.

T12 clone controllers input is 24VDC 3A peak. There is a 30V limit - the MOSFET and sometimes 3.3V regulator is rated for that max. It depends on the version and make. They do fine on 22-19V. So the transformer would work fine, add a rectifier and big filter capacitor 3,300-6,800uF 35-50V to power the T12 controller. T12's suck for a decent stand though.

It's possible to draw a schematic of the OKI controller and see if it can be modded to work with a Hakko 938/888 wand.
