Re: OT Weinschel/Aeroflex 8310 programmable attenuator
Sadly, your comment rings so true... HP may have indeed used Weinschel attenuators, back in the days when Bruno Weinschel was still alive. Weinschel is a shell of what it used to be, not the quality

Re: HP 3400A Upgrade PCBs Available
If the eBay seller has not enabled (at extra cost!) the ability to list outside the host eBay - .com, .de,.uk or whatever - a search by listing number from 'outside' will not find it. I don't know if

Re: HP 3400A Upgrade PCBs Available
Michael may be out of stock which may be why it is not coming up. I sent him a message that members of the group are interested. Will let you all know.

Re: 4195A restoration adventure*
Thats something I do quite often, and I think its not risky if you take a lab supply and limit current to some intelligent value. More than once I had shorted caps that drew most of the current. That

It is Germany. Seller chatted with me on Ebay messaging and said he will provide instructions in English. I asked for the BOM to see if anything unusual for US sourcing, which he promptly provided.
