RCA WO-33A Oscilloscope
#1

Took a new path last week.  Instead of working on the old Vacuum Tube Radios that I love I decided to convert this old Scope into a Curve / Signature Tracer.  Found this guy's Web site by accident, he designs all kinds of fun stuff and if you join Patreon for only $2 a month you can request all that data needed to build one of his circuits.  This was my first time etching my own PCB's using the toner transfer method and boy did it work well. Once you get all the stuff you need.  Working on some surface mount projects for the fun of it now.  Never thought I would like soldering under a microscope.   Icon_cool Icon_lol    I'm not posting this as an advertisement for him.  I'm enjoying it so much I thought I would share.
