If you give me details on the chips, I may have a line to get them for you...

Thank you very much for the offer, however these are VLSI amplifier/attenuators used in the Lecroy 9450A 300 mHz DSOs, quite proprietary, made to Lecroy's specs by an unknown manufacturer. A biggish black box sort of thing labeled only "Channel 1" (or Channel 2, 3, 4)...



The only real source is other model 9450A scopes, all of which are now 16 to 20 years old and suffering the same problems--or power supply issues, also a big pile of proprietary LSI and VLSI stuff. I.e. they are boat-anchors; I need to get my butt in gear and sell the two I have for parts before they are worth nothing...

I got sick of fixing them and bought one of these. I have the previous model, a WJ-332 (no A), the only difference is the colour of the case--mine is ivory--they even use the same firmware.

Very slick....

Here is what I got to use at my last job, working on induction heat treating and melting equipment across the country...that was a wild job...I have seen magnetic fields do unimaginable things lol.

I used a tektronix in school as well, a 2 channel though...They really are fantastic-easy to use and very durable. Grr...this just reminds me how much more useless I become everyday doing the job I am doing now...I want to get back into things like this again...stupid economy...

Cliff, did you teach yourself about electronics or what>? I know you went to school for mechanical engineering, but you seem like you have a vast knowledge of electronics, more than me that's for sure.

I have an associate's in EE that I got from Devry back in '77, but I have picked up most of it over the years (remember there have been quite a few of them) through reading and trial and error--I know a lot more things that don't work than those that do...
