Ham radio update. Got a FULLY OPERATIONAL Heathkit SB-230. Original components throughout. Power output is within spec. I’m replacing the power switch as it’s pretty mushy after all of these years, so arcing will be possible soon, and that’s no bueno for the tube. (Also original). #TeamQRO
Wow - I just looked and vacuum tubes are really expensive now.
The last thing I did with tubes was getting my grandpa's car radio working in high school. I had to fix the vibrator & replace some tubes. I also built a 12V, 10A power supply to drive it. I'm pretty sure my mom sold it after I left home.
The other tube project I had was a "portable" shortwave radio. I'm not sure what happened to it but it was an interesting project.
