Hello Henry, I also recently purchased an ST70 that looks to be all original. I got it with no tubes. Ordered all vintage RCA and Sylvania and mMullard tubes, so faer, except for the new Tung Sol 7591matched quad. I am now in the process of checking all the resistor values. I will probably buy the CE can caps, and maybe the cap resto kit on Ebay? Anyway, I also have the metal insert knobs missing 3 inserts. From what I have found out, the metal insert knobs are shown in the 1964 Eico catalog and it is called the "classic series". I was wondering where you found the metal inserts for the knobs? I need to get some. Also need the top cover. Are you following anyones published resto instructions? I will probably be restoring what I have, themn will start on the simple mods, like the loudness switch.
Thanks, Chuck S
