Hickok 18400-17 Relay USM-118 or Western Electric Cardmatic Tube Tester FR-3035

Description

Replacement Overload Relay for USM-118 or Western Electric Cardmatic Tube Testers
This is a replacement relay board for the hard-to-find 18400-17 overload relay (also known as
5945-00-829-6888, or Line Electric FR-3035)
in the USM-118 Series of Cardmatic Tube Testers. It will also work in the Western Electric KS-15874 series of testers, but see my other auctions for a replacement relay kit for those testers that is easier to install.
This board is made as a drop-in replacement for the 18400-17 relay. It features standoffs that fit the original relay's mounting holes, and solder pads marked with wire colors for easy installation.
The circuit board uses only top grade parts. Fully guaranteed.
You don't get glitz or pizazz on my eBay pages, just really good products and unbeatable service. I specialize in calibration (see my
calibration test bench
), and I build Computerized Tube Testers, so I stand by my test results. :)
