The Heathkit IG-42 Laboratory Type Signal Generator 

Have one and it works great. New Silicon diode bridge with paper and electrolytic caps all replaced. Thanks for showing it!

I love your direct to the point descriptions. Thank you for the Heathkit videos!!

I have this kit on my workbench currently as one of my many unfinished vintage RF projects. Thanks for the video. It was very informative

Always like watching your videos about Heathkit products!

Thanks Jeff, I enjoy all of your videos.

I bought one a couple of months ago. Mint condition with all the original white pointer knobs and Daystrom tubes. Only has a blown RF line choke, which might be from a shorted disc cap on the incoming power, I have not started on this project yet. Oh yeah, I got it for $25.99 on EBay.

Thanks for the overview of a great old piece of gear! 73 - Dino KL0S

I love it thanks for posting nice video

Very much appreciated.

Very nice. Thanks.

Copper plated? HAH!! General Radio uses SILVER plating in theirs! Seriously, copper is good enough. I just got one of these today, and I'm checking it out. It works OK, but needs a thorough cleaning of the switches/pots, and maybe some calibration. Good video, TNX

Your either talking faster or you sped up the video, a little too fast ..

Watch your lights, the shadows are quite distracting as you are moving in background.
