I sent this the other day to the other TekScopes list but thought I would try here too for more ideas. I was given a 2245 recently which of course doesn't work too well. Investigation reveals that

I am still cleaning up and ran across a 1980 Tektronix Catalog, a 1981 Tektronix Catalog, a 1980 HP Catalog, and a 1981 HP Catalog.? All are hard covers.? The are free if you pay the shipping costs

Back in the day...? While I was working at Tek UK (Maidenhead.) The first 492 that came into the UK was unpacked by Sales for a demo, and instantly blown up! Those early units were 115V input

James thanks for your RIFA warning They tend to fail on 240v mains, we are 120v here. This 492 was unused for 20 years and in great shape Thus I leave it for now as it's working fine, but should

Change the Rifas as they WILL blow. I've worked on a few of these PSU's and they are very reliable, however many/most are 40+ years old now and need some TLC. Do you have BOTH manuals? If not I'll

Check the Japanese connectors from Hirose, they made cross version of the Lemo. Jon

The TekWiki site page at https://w140.com/tekwiki/wiki/LEMO_S-series_connector one will find a list of Tektronix units that use those Lemo connectors. DaveD KC0WJN [email protected]> wrote:

My intended point was that a scrap or "spares" 1101 or 1101a could also provide the needed connectors. Chuck Yahoo Mail - Email Simplified
