Hi, All, I am working on a multi-tape project done in 1/4-track and I had cobbled together a quarter track assembly for an A80. I was adjusting the azimuth when sproing--the screw stripped out. I had another A80 head block I got when i purchased my load that had the same issue. The hole can be drilled out and threaded and have a screw insert put in, so it's repairable, but I don't have time or the parts to do it right now. So I looked for another solution and thought I'd mention this issue. When I put together another Sony APR-5000 quarter track head block, to continue this project, I noticed the azimuth screw was very stiff, so I pulled it out and lubricated it with a few drops of Kluber Constant GLY 2100 lithium soap -- what Studer used in their late model capstan motors and my go-to lubricant for mechanical linkages. Works like an absolute charm now! Cheers, Richard -- Richard L.
