I recently purchased an Otari MX5050 BIII and have been trying to buy the NAB hub adaptors on eBay. My first attempt resulted in a pair that was intended for 1/2" tape and did not fit. Although the spindle size was the same the hubs did not have the grooves corresponding to the 3 splines on my spindles. The spindles are 1.25" long and the splines are approximately 3/4". The second pair of adaptors I purchased had the grooves but they are only about 3/8" deep and the hubs do not mount flush with the wheels on the deck. Both hubs were made by Otari. Did Otari change the design of the hubs between the BII and the BIII models of the MX5050? Does anyone know what I should purchase that will accommodate the full 3/4" length of the splines?

P.S. I played around with the hubs and by loosening the knobs I managed to get the hubs to go over the splines and into position on the spindles. When I try to tighten the knob the hub assembly pushes itself backwards off the spindle. Is there a trick to making these work or do I just have the wrong model hub for this tape deck?

I thought the BIII had the spindles like most consumer decks, that the tip pulls out and twists. Meaning you can use ant NAB dadpter that a Teac, Revox or Sony uses. The BII has solid shaft spidles which need Otari KWOH009 or TW-670. I like VIF adapters on my BII machines.

That seems to explain it. The BIII does have the tip that pulls out and twists and the hub adaptor I purchased was the KWOHOO9. I will return these and find some teac adaptors. Thanks.
