The supply is 750V 12mA / side.
The usage of diodes 13,14,18,19 I don't know.
The TX 500K transformer is 6 & 39 Turns.

Re: Comments to schematic.
THANKS!!!!!!!!!!!!!!!!!
That is great.. I looked over the schematics and was able to read just about everything.
There were 2 things I was not sure about, so I figured I'd check with you to be sure.
What is the equation for gain in the upper right hand corner?
What are the part numbers for A4 through A6? I get CA3080 for all parts, but I wanted to check.
Thanks again!

Hi Bob
>What is the equation for gain in the upper right hand >corner?
I don't know exactly. In principle it should
follow th "sonar equation" but I have tested
to mix with this and found that it is very
unsensitive. (In my machine )
I will the the curve on the oscilloscope and write
the figures.

It is in fact CA3280 wich is 2 CA3080 in sam case.
Since CA 3280 is obsolete use CA3080.
