Hi! I picked up an old Riverside Tool jack plane and I'm working through several of rhe rehab guides online for them. A lot of them mention flattening out any dents in the chipbreaker by sanding/grinding them on a flat surface. My concern is that if I grind this all the way out, I'll have significantly changed the profile of the component. Am I overthinking this?
Edit!
I have been thoroughly and soundly corrected! This is not goop, it's glue! I will test the goop for conductance and test the transistors! Thank you for the advice!
For reference, I've never recapped a receiver before. I can solder pretty well but I'm no pro. Picked up this HK 3480 for free from my local buy nothing group. It goes into protect mode when it starts up. Had a couple fuses that were very obviously toasted when I opened it up, so I neglected to look even a little bit closer. It seems like every single cap larger than a certain size on this board has fully shit itself. (Circled in red)
I believe all I should need to do is desolder them, clean up the electrolytic goop, make sure it hasn't damaged any adjacent components, and solder matching capacitors back in their place. Is that it?
I'm also wondering if I'd want to replace ALL the caps (even the little ones) to avoid this in the future. That's a lot of caps. I don't think I'll find my zen recapping this board, so it would have to be worth it. What do y'all estimate on parts, how long do you reckon it would take, and is it even worth it to recap this board if eventually I'd like to get one with an hdmi input or two?
Update: I tested the four big transistors in the front attached to the heat sink. Results are as follows.
