Solartron instruments are, not suprisingly,
fairly common in England. I
have an LM1420.2 (the .2 meaning it's got the BCD output socket on the
back), which is all discrete transistors with nixie tubes for the
display. And a somewhat better model (LM1602???) which uses DTL chips.
The former certainly contains a Seston Standard Cell, I suspect the
latter does too (ass, incidentally, does that Blackburn valved DVM I
mentioned in another message).
A DVM with a built-in standard cell?? Neat! Got pics and/or schematics?
I'd love to see that.
