Decided to recap my B77 mk1 (it was about the time). I had the schematics and could verify the cap types that I found on the several boards (8 larger PCBs) inside the B77. The main use for my B77 is to use it as a tape delay and it while it was performing okay, it had some issues, both mechanical and electric. No wonder since the B77 mk1's were manufactured in 1977-80, so this tape machine is 40+ years old. Though of course it's largely made of Studer parts so it's made to last to a certain point. Below is a table of the electrolytic capacitors + some other important caps that are at least good to replace. On the PCBs there are also lots of Tantalum caps that I left alone at this time. Considering their age, it might be good to replace them too. They are not listed on the table.
