We are still in the process of relocation from MO to TN. Building being what it is these days we now expect to be moving in at the beginning of September and should have our equipment and
component parts mid-month. At that point we'll be able to start taking in custom build work again. Our apologies for the delay.
A couple of recent updates:
1- Mexican windings for OT33PP, OT42PP, OT19PP are on their way to us. So when we can assemble/varnish again these will become another stock offering. The OT20SE winding from the
Mexico plant is being reviewed currently but looks good.
2- Domestic USPS performance is getting better. We'll probably remove all the dire warnings we have on EBay listings shortly as the FEDEX Smartpost shipping is typically 25 to 30% more
expensive. I may swap FEDEX back to primary choice in November......
At some point this year I'll see if I can't work up a spreadsheet of custom designs we've worked out in the past 15 years. It may give some of you ideas for starting points. I don't
always know the applications involved, but where I do I'd drop that in.
