Repairing a BOSS SP202: Volume Knob

[@foansmusic5603]

I just wanna say I love this channel. I love restoration channels but I've never seen anyone repair audio gear like this. I can't wait to see more.

Hey thanks for that! My goal was to upload something that hadn't been documented yet. Really glad to see it resonate 🙏🏽

Yezzer!!

[@acetateassassin7933]

Any idea why mine has no sound in the input but when I put in the output I can hear sound when I plug my phone into it? I changed the rca and the volume pots but same thing.

[@sumawav]

Appreciate you! I've been well thanks much for asking. Currently editing up an mpc500 video.

Nice job. I have an issue where the sound cuts out if i bump the line in / Out phono jacks. Thinking it must be weak solder joints inside the 202 linking the sockets to the board. Have you ever experienced this issue before?

[@sumawav]

Hey thanks for watching! I’ve definitely seen that before. It is indeed usually weak or cracked solder joint. Very common on the SP303.

[@SULSABEATS]

What was the copper coloured tape you were using when soldering? And what is it for?

[@sumawav]

It's called copper wick or sometimes copper braid. It's used for removing solder from a board. By applying heat to the wick and solder, the solder will melt and conveniently get sucked up by the wick. Super useful!

Nice work! Where did you source your replacement? I am having no joy finding one:(

[@sumawav]

I found one on eBay back in April.

@@sumawav do you have a link ? Need a spare part for the volume ..like the same what you did..

[@tone2846]

You think you can fix control knob ?

[@sumawav]

@@tone2846 i’m confident I can fix it. The difficulty is finding the replacement part 😬

@@sumawav mines still works it just jumps when I try to set the filters in I have to hold down a direction to get the filter to stick. Just wish I could turn it without it holding it in the direction. I believe the previous owner had dropped the unit /: I’m still able to sample and add effects but it’s Janky. I just record the effect into the sp404 sx.
