Tektronix gain adjuster adapters for sale on eBay provide useful connectors for 500 extensions

John Williams

These little gain adjuster adapters for setting the main vertical amplifier gain in 530 540 and 550 mainframes show up on eBay frequently and are not super pricey. I have a couple now. While not used for their intended purpose very much, they can be a source of useful connectors for making up extender cables and other times you might want a male and/or female 16 pin set. The connectors themselves are scarce and expensive new. It is easy to disassemble the adapter and reuse the connectors in some other application. Not a bad bit of kit to have in a drawer.
