Hi Barry, There are many manufacturers making the twinax male straight plug today for the balanced jack on the 390s. There's Pasternack PE4104, PE-S330; ARC - 8-299, AMPHENOL - 82-5589-RFX, 162100; SPC Technology / SAMAR - SPC21084; Connex 162100; Pan Pacific <https://marvac.com/collections/pan-pacific> TWX-3501 <https://marvac.com/collections/twinax-connectors/products/twx-3501>; Aim Cambridge 27-9087 <https://marvac.com/collections/twinax-connectors/products/27-9087>, AIM 27-9080; AVA 403000 and others.
If anyone would like one, I'll sell them an AVA 403000 for $3 + postage.
