1- New Standard Product Offerings for OT5PP, OT8SE and OT12PP+ in revised versions are now in stock from the new Mexican supplier. Pricing will be improved significantly if you can use the
2- Created (4) new HiFi/Audio offerings based upon success we've had building low distortion versions of our current designs with more iron and more complex interleaved winding sections. The
idea here is low distortion and wider frequency response well beyond guitar amp requirements. See OT10SE-HF, OT20PP-HF, OT19PP-DYN-US, OT22PP-DYN-US and OT43PP-DYN70 spec sheets.
Note- Our US cover and frame supplier (BAHRS) closed up shop at the end of September & sold their tooling to a new business. We're between orders now on some sizes of covers
(HC87). That may impact what we stock for a couple of months.
We are seeing a lot of customers with time for projects currently. If we can hit the requirement with one of our standard material sets we have a pretty good track record on custom builds. If
you've got something weird or wonderful that you need ........ we do that ;-)
