Hi guys!

So I’d like to surprise my mom and fix her old stereo which she no longer uses, due to it being making all sort of crackling noises, and no longer having a very large LPs collection. It was a nice one and she’s fond of it. It’s an old Scott 440A, and it has hooked both an LP player and a radio. It did have a tape player recorder, but I think that eventually got broken and thrown out. My solution would need two steps:

-I need to clean the amp potentiometers, specially the volume one, makes really loud cracks when moved. I have no idea how to do this! Is there any guide or youtube video showing how to do it?

-I’d like to buy a bluetooth DAC/CD player combo, so she can turn the AUX input and use it to play either CDs or music from the phone or the laptop in the bluetooth mode. She does have a cheap CD player connected to it, and I hooked also a cheap bluetooth DAC to the CD player external input, but the whole thing is a mess. She needs to remember to go aux, then choose the external input in the CD, then turn on the crappy USB bluetooth dongle thingy. I’d like a better looking single unit that does both BT and CD if needed. Is there such thing? Any recommendations?

Thanks a lot!
