My transistor & diode test station

[Chuck D. Bones]

I dusted off my old Heathkit Curve Tracer and hooked it up to a USB Digital Oscilloscope.
Chinese Transistor Tester - $18
Refurbed Lenovo laptop - $160
LabNation USB DSO - $220
HeathKit IT-1121 Curve Tracer - $55 (in 1974)
Finally being able to test and sort all of my transistors and diodes - priceless

The red X-Y plot on the screen is the transistor Ic vs Vce & Ib family of curves. I have a 2N1308 in the tester. Pay no attention to all of the crap in the background.

Look s very cool !

Knobs , buttons and switches let me play with that Heathkit...that thing was build when things were built to last !

I bet it come with a thick manual back in the day....

Yup. I actually found a scan of the manual online. All 107 pages.

That’s awesome !

Came in handy when I had to get it working again. I'm already planning a mod for it, are you surprised? The one thing it can't do is test MOSFETs, but a DPDT toggle switch will fix that.
