Heathkit IT-28

Workshop Project #23 - Heathkit IT-28 I am always out there, hunting for interesting devices on e-bay... and I couldn't believe my luck when I found this little gem of old school homebrew electronics: a Heathkit IT-28 on sale in the UK; I put in a bid and - just by sheer luck - won the auction with about 3 Euro and change under my maximum bid. Either that or the system is rigged. But hey, here I am: proud owner of an old school capacitor tester. The instruction manual, complete with description and circuit diagram, is out there as PDF and was really helpful in making sense of the typical tube point-to-point wiring. They sure cared more about function than recognizable wire paths back then. Join in as I unpack and fix up this little gem! As seen on ‪@MrCarlsonsLab‬ you might say: he has one of those and occasionally uses it too! 0:00 Intro / Overview 1:20 Unboxing / Disassembly Start / Transformer 3:05 Front Panel Disassembly / Goo? 4:50 Electrolytics / Resistor / Voltage Switch Claening 6:48 Mains Switch Claening / Mode Switch Claening 8:09 Binding Posts / Case Straightening 9:04 Case Painting 9:57 Power Cord / Panel Mounting 11:26 Binding Posts / Electrlytics Replacement 12:37 Adding Case and Power Plug / Power Up / Tube Test / Blown Fuse 14:22 Power Up with New Eye Tube 15:00 Leakage Circuit Outline / Calibration 16:22 Testing the Replaced Electrolytics! / Replacing Reference Caps 17:36 Bridge Circuit Features / Carry Handle 18:40 Overview / Summary / Credits / Outtake Music: My Train's A Comin' Unicorn Heads (YouTube Audio Library) You can support me on Ko-Fi: https://ko-fi.com/atkelar
