Keritech Snail Mail: Resistors and Relays

Vintage mailbag time again! NOS R15 4PDT industrial relays for an upcoming project, and an absolutely beautiful resistor decade box made by Ulrich, probably 1940s/50s, but in a damaged condition. This is gonna make a restoration project... after I get proper resistors for it. 0:00 Intro 1:11 First Package 2:35 Lumel R15 4PDT 3:35 Upcoming Matrix Switcher Project 5:35 3U Rack Enclosure 8:00 Relay Layout 10:15 1978! 11:10 Second Box 12:00 Ulrich Decade Resistor 12:55 Possible Origins 13:40 Disassembly 19:32 Faceplate Lifting 20:23 The Switches 23:!5 Digging Deeper! 24:30 The Guts 25:40 Raansacked 28:17 So Much Copper! 30:17 Measuring 33:15 Where It Fails 36:20 Afterword Support me on my Patreon page at https://www.patreon.com/KeritechElectronics or via PayPal https://paypal.me/keritech Instagram - https://www.instagram.com/KeriSzafir Hackaday - https://hackaday.io/keritech #ElectronicsCreators #Keritech #Electronics
