if you have the schematics for the 914-918a are these chassis 23inch also like the 908? and does those 2 chassis use a hv tripler? im working with don lindsly on if i could use the fly for the smaller chassis for the 908 but hes looking to see the schematics as well. thanks timmy

IIRC, the TS914 were all 23EGP equipped. The 918's were built using 21,23& 25 CRT's. They all used 3AT2 HV rect tubes. The ETS908 were a good earlier design. The TS914,918 and 921 was the cost-cutting later design. The smaller chassis used a focus voltage dropping resistor from the second anode source.
