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!
On a high level, you can get a cleaner like Deoxit D5 in a spray bottle. Most pots have a slit in them so you can spray into them, then turn the pot through its range a bunch of times. It’s worth a try as a start. Obviously do it while the unit is unplugged.
If you want to consider a more aggressive rebuild, like a capacitor replacement, maybe find a cheap old amplifier at the thrift shop to use as practice for desoldering/resoldering.
You might be able to connect the BT to one input on the amp, like the tape input, and the CD to another.
Thanks, i think I’ll get deoxit definitely, I’ve seen it recommended everywhere.
Regarding the dac…there is only one left. Phono and radio are taken. So only aux was left… That’s why I’m trying to go for something covering both. If not possible, could you recommend a good BT DAC?
