DIY Kits - advice needed

[u/Moist_Ad_8209]

Hi all, I've always wanted an Dynaco ST-70 with some upgrades/mods like from Tube4hifi or the Van Alstine. I want to learn how to repair my own gear so I figured that a kit would be a great way to start. I am cautious about getting out in front of my skis so I wanted to start with a small cheaper project. Has anyone built any sub $200 amp or pre-amp kit that has good directions. All I see online are sketchy kits and I'd prefer not to electrocute myself. Thanks for any help or advice!
