Hi Folks, I need a schematic for this transistor curve tracer, I went on a site and just found the manual. eBay has one for $75.00 and if possible I would like to build one myself.
Does anyone have a schematic and parts list ?

Thank You Tony

Thanks for the information, I would to build one just to see how it works. I agree somewhat about junk and I’m not paying $75.00.

Your link was for the manual, I need the complete schematic with a parts list.
Thanks

Schematic on the third page has schematic with all the values of the components. All the information you need to build it is there.

Thank you for the additional information and I do see the schematic and parts listed. A quick question regarding the transformer, it shows a ratio of 2:1. Also a part # for the xformer, any idea what manufacturer goes with part number.
“T-1”

Thank You .....Tony

Tony,

Save the trouble - build the Octopus as outlined in the 1950's era Electronics Installation and Maintenance Bulletin (NAVY):

Seems every shop had one until the Huntron Trackers came about. I built my first one as a teen, from a photocopy of the same schematic. One 6.3V filament transformer, three resistors (560 ohms, 1K ohms, and 100 ohms), a power switch, and a DPDT switch if you want to use an audio oscillator instead of 60Hz.
