I just purchased an Akai GX 280D SS and am getting everything cleaned and ready to operate. The only problem I found is the supply reel table and the take-up reel table both drag. I pulled both tables and they each have one disc spacer. No matter what tape reel I use, they both drag. I put the two separate spacers under the same table and they run perfect and without drag. Is there supposed to be two spacers for each table? I don't mind fabricating a thicker spacer but hate to incase I ever sell the unit. I can't find an adjustment of any kind for the tables. Thank you!
