As I said in my previous scope thread “this did not take a lot of effort” :

“Parts only” scope was missing a power cord, lever switch “ knobs”, had a weak battery pack and was abused by USPS.

Fortunately, the little scope was not damaged so after rounding up the missing parts, cleaning switches, and rebuilding the battery pack, I have a nicely functioning compact 4 mhz portable, FLOATABLE Oscilloscope from the early ‘70s :yes:

Looking at the inside, I am really glad that no parts replacment was needed:

Harness wires are soldered to the board, but transistors plug in! :scratch2:

Looks like they sent it to you at the flat box rate...er um I mean in a flat rate box. :D

The Sony Tek 323 configuration resembles that of the 4 inch Sony portable TV, in fact the handle hardware appears to be identical. Sony 4-204 UW pictured next to the 323 scope, both running on batteries:

Wow, that's a really small scope. Having one of those sonys my self makes that picture give a good sense of scale.

Tektronix made smaller scopes, the 200 series. I just finished rebuilding the battery packs for my 211, so here is a photo of the 321a, 323 and the diminutive 211 running on batteries:

The 211 measures 5” W x 2.75” H x 9” D. For more information about the 200 series scopes, visit the Vintage Tek site. https://vintagetek.org/200-series-oscilloscopes/
