Tektronix AA501 [A]

Seems every pdf I find on the net for the AA501 is missing the circuit of the autorange function on the A12 board, including the one on this site.

If any one can help with that page it would be most appreciated.

Cheers

Except for the power supply section, that is adapted for the TM50x frames, all the

other cicruits are EXACTLY the same as that of 26A1.
I checked with mine AM501. Please ignore the indicated DC levels.
You can find the 26A1 manual at http://w140.com/tekwiki/wiki/Main_Page, under

paragraph: 2600 Series.

Ignore please my above answer. I confused the AA501 with the AM501. Sorry, but any way, this may be usefull for anyone conserning about the AM501 Op Amp.
