Your jukebox is 1975 vintage and the capacitors are beyond their useful life expectancy. If you are keeping the box, replacing the electrolytic caps is a good way to prevent trouble down the road. The electrolytic can caps, the PEC 4 units on the driver board, the op amp IC units on the pre amp boards and finally any "tropical fish" striped capacitors that are flaking or crumbling should be replaced.....these are the components that are failing in 2023. I'm sure more will be on this list as the years go by. But guess what........all these components are available and inexpensive so replacing them is good insurance and good practice......
Yes, it will. In addition to the short circuit/explosion risk, capacitors and diodes get weaker and weaker as they age and their chemical makeup decays, which can result in awful/weak sounding sound output, wonky behavior from other components, and generally unpredictable results from all moving parts. If the diodes for the speakers for example aren't getting enough juice they will sound crackly and dull and you might also hear transformer humming.
The 441 has a tube amplifier (even though it was 1969!) which I am not familiar with. All the other Rockolas from this era had transistorized amps which are less costly to revamp. Other than the common sense things like reseating all the tubes and being sure the turn table platter didn' t get dislodged from the idler wheel, I really wouldn't have much to offer. Sorry. See what others say
@@williamweisel2176 Thanks for the reply! After examining the unit further and touching the connections under the tone arm, I think that my be the issue. Last year, I installed a new cartridge and it was very difficult to make all the solder connections. I think I'll pursue this angle. Thanks again. Enjoy your videos.
Fabulous, need more people interested in electronic history and preservation out there, keep on rocking!
Great work! Keep up your enthusiasm! As a retired electronics tech, it's good to to see the old stuff being brought back to life.
Appreciate the videos. Has helped a lot in my restorations. Thanks !!! (polite advice... you should get a tripod for the camera).
Nice to see there someone else like me that has a nice way to spend time repairing stuff 😊
It IS fun to fix things........bringing music machines back to life is worthwhile. Thanks for the comment.........Mr President!
@@williamweisel2176 lol thanks for the comment
And you are welcome
good moring i have a 52280-A anp can you tell were i can get the male and female connectors on the pc. boards any help thank you feom john
Nice videos, thank you. I’ve got a 459 rockola box and haven’t changed any caps yet, does it make a difference in the sound quality and output?

My model 441 amp works but since recently moving the unit via truck, it now the sound is not clear nor can I get much volume. Any ideas?
