Since I almost only do DC and 'a few' kHz, I used my new "moderate frequency hobbyist oscilloscope" savings money to buy 3x Agilent 34970A DAQ/Switch units and an Escort 3146A DMM (total USD 340 - not too bad imo). I can get by with a sound card as before ...
One unit will probably run good after change of battery. It passes full self test with a (swapped DMM board from one of the 'dead' units - good sign) most of the time with 2 AAA in parallel with the 3 V Li***-battery. I am waiting for a MUX card (USD 200 on fleabay
). If it becomes well behaved it will get a life as permanent voltage ref babysitter.
Two units have broken transformer primary winding, and must have been run with 220 V in 110 V connection. No signs of burning inside box - and secondary windings are OK. So the main board might have survived. Will swap the running transformer around a sunny day
All I can find is:

http://cp.literature.agilent.com/litweb/pdf/34970-90012.pdfp. 183 gives no hits but the manual itself.
Anyone can help find a transformer or two - from a dealer or from an abandoned box?
Also - I am too lazy to run for new old batteries. In the 34972A part of the manual it says 'use a CR2032'. Anyone tried this?
Thanks.
