The problem is a stand alone diff amp is going to be a low volume thing to sell
Two of the best ones (one no longer made) are the Preamble DA1820/1822(A) and DA1855(A) http://cdn.teledynelecroy.com/files/manuals/da1820-1822_om.pdf They were bought out by LeCroy and then LeCroy by Teledyne. The 1855 (and 1855A) sell for quite a bit expect to pay around $1000 for one. I've seen 1822's for less the $200 but you have to have auto notify on the auction sites set up. I got one on the big auction site for $100 as a Buy-it-now. But that was just luck. Outside of the physics/chem/bio market there isn't anything.. a quick scan on Google http://www.tegam.com/product.asp?modelNumber=4040B https://www.a-msystems.com/s-130-acdc-differential-amplifier-model-3000.aspx http://www.bakelectronicsinc.com/2-3.html On Mon, Nov 23, 2015 at 12:00 PM, Andrea Baldoni <[email protected]> wrote: > On Mon, Nov 23, 2015 at 07:06:59PM +0000, Mark Sims wrote: > > > Maybe a Tektronix AM502 module and the single slot TM501 mainframe? > > Hello Mark. > > Yes, the AM502 is the thing I am searching, but they are not very cheap for > a 1977 vintage, in particular adding the mainframe. > > It's possible that in 38 years no maker did anything like? > Looking better, all other modules I saw aren't equipped with front panel > output, > because are in effect vertical oscilloscope amplifiers and thus the output > is > on the backplane.
