Just pulled trigger on flea-bay:
$21.99 with free ship.

BiOzZ:
I have not seen a full reverse engineering of the frontend, but in the case of JoeQSmith's modifications, would it be out of it question to simply pull the OPA4330 and replace a higher bandwidth higher spec pin compatible AD8630 and tap the output directly or from the range switch? Or does it contain discrete filtering making this option a worse choice than making a seperate discrete parallel amplifier?

stj:
i dont think that can be answered without somebody drawing or finding (requesting??) a schematic.

BiOzZ:
true, mines in the mail i'll take the time when it does finally arrive to reverse as much as i can of the frontend and post here

BiOzZ:
i started working on the reverse engineering but in the end chose not to reverse the whole front end, its not filtered at the output, the output is very easy to access and the impedance of the meter on the current ranges is 150K
Its actually too unfiltered giving quite a bit of noise on the output so im going to be inserting an active low pass filter when i complete it
im waiting on the improved op amps to come in from digikey and will be posting what i did here in detail
