Re: Seeburg Symphonola 147

Holy crap... I totally didnt think of that... this thing is mostly made out of resistors and they are probably all in need of replacement...

Re: Seeburg Symphonola 147

Thanks for all your help! I post my results when the parts arrive. Hopefully the worst of the electrical problems are behind me now!

Re: Seeburg Symphonola 147

Well I cleaned the switch (heres hoping I dont have to replace it!) As for the electrolytic attached to the chassis I was actually hoping to replace all the caps since most seem to be in poor condition though, only two seem to have burst open... I'm currently having an issue finding caps to match the requirements of the existing ones. I'm aware that the voltage can be slightly higher than the ones in there, but what about the capacitance? is there some sort of "margin of error"?

.01uF 1000v
.1uF 600v
.1uF 400v...

Ok here's a couple of pix of the caps and the amp itself......

Not sure if you guys will be able to help, but I figured its worth a shot. I'm currently in the procces of trying to recap the MA1-L6 Master Amp in my Dad's old jukebox. Its had a crackling noise for years that the previous owner had attributed to a blown cap, but I only recently got around to taking it appart. One of the big problems I've been running into is outdated markings on the caps (it IS over 60 years old after all!) I've only recapped motherboards and a couple of monitor power supplies so I was a little unprepared for the ratings I was seeing on them:
