Thats quite funny Bob, I collect Taylor gear and the 90A is one I am missing!

I did however recently purchase the genuine manual for the 90A in anticipation on getting the meter, but it's the series 2 version.

I have information for the Taylor 90 & 90A universal meter, I will try and scan the circuit diagrams later.

Blimey, never expected so many people to have the info, will save me digging the scanner out though, thanks.

Here are the circuit diagrams for the Taylor 90 & 90A universal meters.

The first circuit is for the Taylor Series 90 issue 5 Serial Nos. 90/10501 & up. this has 38 ranges with a 1mA type 425 meter movement, this has 5 scales on the meter. The Taylor Model 90 Series 8 Serial Nos. 90/11501 & up has a 40 ranges (lower ranges are different) and 6 scales on the meter (not shown on diagram).

The second circuit is for the Taylor Model 90A (no Serial Nos. given in book), this has 40 ranges with a 1mA type 400 meter movement, this has 4 scales on the meter.

As usual with other Taylor manuals, no component values are given on the circuit diagrams and there are probably other versions that may have different circuitry inside.
