No worries. It's a plan to have them on stock :)

Dear friends, thank you for waiting so long. I want to update with some news. After 3 revisions of the bobbin molding tool and 4 revisions of the laminations stamping tool, all the parts are "on stock". First 20 pairs of the coils are in the production and it will be used to determine the final magnetics properties of the laminations. It will ask for a few laminations heat treatment revisions, but it will happen.... As soon I confirm it I will start with the first batch (50 pieces). In that moment Vac11 will start to accept purchases. :) I'm really excited about this little transformer reissue and again, thanks for the support and trust. Photos of the production will be presented soon. Cheers!

Hey everybody. I collected all the material needed and already made a lot of prototypes but before I start this first batch production I wanted to "practice" a little. So, I decided to repair some vintage broken T14/1's and to analyse some more how it was produced through the years. I found that "dead guys" were from 1950-1970 production and as I suspected some parameters were changing through those years.

In the first place the laminations alloy went through few revisions. To be more clear, early ones don't match magnetics properties with the later ones. I will proceed with the revision from the 60's because it sounded great to my ear ;).

Also, DCR values were +/-few%, meaning that primary DCR varied from 2900-3150ohms and secondary from 28-31ohm (one half).

To be honest, that really does not matter because the magnet wire manufacturers give DCR tolerance around +/-7% for this kind of wire.

BTW, I don't recommend measuring the primary of this transformer unless you have a special ohmmeter where you can control the current. The wire is really thin and a small DCR can damage it.
Since the transformers were varnished, I had o find the right varnish solvent.

it took me 48 hours to be sure the laminations are free to go out.

After that they were "resting" some more to be 100% clean

You can see how different the laminations is looking. Darker ones are the older ones

Here are the new winded coils ready to be filled with the old laminations.

Here is the first one repaired. Still not varnished but I can make it ;)

Please let me know if you are ready for this. If yes, Vac11, should we proceed?

Great news!! Yes, Im ready.
Cool. Let's say that I need 45 days for the production of the first batch. @Vac11 , we should decide about few details regarding packaging, shipping, money collecting, etc... Let's arrange some call about it. OK?

Update:
Vac11 and I already started conversation about all the details needed to be determined here. So far we figured out that I will send him the complete batch and he will sort out individual packages to you. We do our best to cut down all possible expenses in hope to avoid exta fees on the end side. We will keep updating ....

One more update. We started with the winding job but I'm not happy with the one of the magnet wire quality. Probably too old wire. So, I made the order from the diferent manufacturer. I expect it soon, say next week. :)
