Adds the TIP-55A substitution procedure, the spark gaps and the flyback marking) | ||||

Main logic board has only C7-C10 47uF 16V, not 4700uF/2200uF/1000uF/220uF/10uF; the 4700uF 25V is C1 on the display assembly; C101-C123 do not exist; no 7805 on the PET; board list corrected to 320008/320081/320132/320137; CRT and mains hazards stated properly; Unverified data cleared) | ||||
