Hi Mike! I appreciate this series of videos showing the HeathKit SB200 upgrade. I have one in great condition, but after watching your videos, I was encouraged to improve my amp. Thank you very much and congratulations on the work. 73 of PY1TS, Carlos, from Brazil. ps: If possible, I would like to see a video showing its behavior after the modifications.
I can't emphasize enough the importance of documenting each step with pics or video. Unless you do this for a living it's almost a certainty that you will later be very grateful you had the foresight to do so.
I got 2 of them . 1 older and 1 newer . both have BNC input. newer one does not have 10 meter . both have power supply caps bad and older one the bord burned with diodes . got most parts I need. 73's
Gentle suggestion: when working on high-potential circuits...remove rings and/or metal watches/bracelets, even if unplugged and discharged. Please? No criticism, mind you, just abundance of safety.
DUDE! Put a towel in-between the cabinet and your workbench. Don't drag the cabinet around directly on that bench and scratch it. Otherwise great video, especially the discharging :)
FINALLY a video that shows discharging. I wanted to ensure I was doing it correctly. Thank you 😁

Just got one and it needs some work and this helps out tremendously.

Thanks very much for uploading your restoration, regards Carl.

THANKS MIKE FEDLER
Would be nice to squeeze a couple of 813's in place of the 572b's

Maybe you didn't notice that the surface on my workbench is covered with cardboard. Take a closer look.
@@mefedler I didn't see that. Good stuff.
I agree. You can hear the grit scratching it as he turns it. But good video
