Refurbing a Hitachi V-422 to use on my bench. A donor scope I have gave me a decent case and front panel, then I replaced the electrolytics, but then my scope threw me a curve ball to fix! #jazztech #electronics #oscilloscope #Hitachi #scope #homelab #testequipment #faultfinding #soldering…

I have this task ahead of me, but it seems so daunting, and I feel a bit intimidated.
It's a really nice unit. Techtronix 465. But even trying to find the correct service manual seems tricky. I've managed to get the manual for the 465, but it looks different, and only have half the controls mine has.
I bought a dso138 to continue working in the mean time, but it is terrible.
Ps; subscribed. Looking forward to new content.
Nice job!

I subscribed because it's very interesting. I look forward to the calibration video as will do mine too.
I have the exact same oscilloscope. I use it to test audio stuff. It's not fast enough for rf stuff. But it's good enough for audio.
I only knew 1 other woman who was also an electronic technician. She was in my electronic classes back then.
It's not common.
Very useful video, mine have a worn out pot. I need to replace it when I have some time and no repairs… which didn't happened since 2018.. I'm the only technician in a 100 miles radius, so I'm always busy.
You can’t beat a bit of foam cleaner and it is good to see you’re using branded caps. Excellent video Jane, Thanks
I’ll have to check out that cleaning spray you used on the panel; looks like a great addition to one’s tool bag.
Nice fix, and congrats on getting close to 1K after half a year and 54 videos, both being less than a quarter of what it took me to reach that point.
Great video! Only 2 subs 'till 1000! Oscilloscopes are a favorite of mine. My father was a service technician at Tektronix from 1966 until 1996 or so. He taught me how to use a 'scope when I was in Jr. high school. My first personal 'scope as an Eico service 'scope from the 1950s. It didn't originally have a triggered time base, it used a synchronized multivibrator for sweep. I built a triggered timebase from a 555 timer. Not too fast, but good enough for a 1MHz 'scope. I can't wait for the calibration video!
Nicely done and an excellent result! Looking forward to the calibration. I frequently find cracked solder joints when refurbishing test equipment – I now routinely run all the cards under the microscope for a quick scan. Regards, David
