A friend gave me this Eico 232 VTVM and I'm having trouble locating the schematic for it. This one seems to be a later version because it has solid state diodes to replace the 6AL5 duo diode tube. I would say maybe early 60s. All my searches have resulted in the schematic for a 12AU7 and 6AL5 configuration. This one has only a 6FQ7/6CG7 replacing the 12AU7. Any help is appreciated.
