Service Department Bulletin From Plessey-Garrard 1975
Interesting tips & fixes memo from the Service department. Confirmation that lower motor bearing can be lubed in place, without complete disassembly. Valuable motor-shaft realignment and motor spindown-time information. Perhaps the first official siting of the Inline Lightbulb voltage-pad trick, and (very) unusual advice regarding the greasebearing. Worthwhile to note that by 1975 the 301 was long gone, and Plessey-acquisition Garrard would discontinue the 401 by the next year. So the 301 assistance here was being offered as last resort support. It does come across as a compilation of all the accumulated fixes known to be simple enough for the intrepid Lp Enthusiast to navigate. |
