Slight cracle from one channel of Jolida SJ302a


Would anyone know what might cause a slight crackel noise to come from one channel of my Jolida sj302a? It is constant and occurs even with the volume at minumum. This amp was just bought from the Audiogon classifieds so I do not have a history on it.

Thanks,

I had a 302a a few years back... It developed a slight, intermittent crackling sound and, a few days later, the fuse blew out. Changed it out, and it played beautifully after that.

I'd check the tubes first, that's most likely the culprit... but, fuses are less than a buck, so if it's not the tubes, you might try replacing the fuse in the back.

Enjoy the amp... it's a fantastic piece of equipment.

Best,

I own several Jolida's. When you change the tubes try cleaning the tube sockets with some good contact cleaner. I've had crackling show up on retubing and cleaning the sockets fixed it.
Ah, those crackling Jolidas!!!:^)

I want to say that Rives is probably right on his second guess... I just want to add that it could be a coupling capacitor(s) that don't have a good DC isolation anymore.

Most-likely it's possible to replace all coupling capacitors with better more reliable versions and better sounding that you should inquire for more.
