Tek 222 Schematic
« on: March 12, 2019, 05:07:17 PM »
Hello Everyone, I joined the forum today and I wanted to share my most recent video repair.  I assembled a 9.4 volt AA NiMH battery pack series parallel 14 batteries, just as shown in Mr. Carlson's Lab video about his Tek 224.  I inadvertently wired the batteries reverse polarity, which let the smoke out  :-\.  I made two videos, I linked them below.

I would also like to ask if anyone has a schematic for this Tektronix 222 scope, I would very much like a copy.

Thanks for sharing the videos. I added the directs to the videos in your post. I really need to get the youtube links to work by user uploads.

I may have that manual. Will look this coming week end.
