Thanks, that diagram is a gift from heaven. Excellent!. Mister Disc works like a charm again!. I just need a spring for the cover, but i can probably fix that easily enough...

Sound Burger - only 1 channel plays.

I have one of these, we used to use it at record shows. It plays fine, but when I plug headphones into either the A or B jack, there is only sound from the R Channel...is that easily repaired? I want to sell it.

Nature of repair

Posted Mon, 08/01/2011 - 19:33 by googlegirl

Thanks for the link...sadly I don't understand the diagrams (guess I should have paid more attention when my brother was assembling his ham radio and soldering stuff together). I guess my question is...is this 'one channel' sound probably a loose wire, and is that an easy fix? To someone who might understand those diagrams, that is. Thank you for your help!

I have another question, about a totally different turntable. We also own a Dual, and just reconnected it to the amplifier after years out of service. The volume when listening through headphones is perfect, but when using the external speakers it has to be really, really cranked. We have three pairs of speakers, and use a splitter (Monster Cable Speaker Selector, with Amplifier protection) to control them individually...could that be the problem? And I apologize for not using proper terminology...I just like listening to music, don't understand the mechanics.

Lastly, have a manual Ariston turntable...bought as a present for my husband 30 years ago, but too sensitive and we could never get the hang of lifting the needle at the end of a record. Is that something that still has value? I'm not so much interested in the money on this or the Soundburger, more in getting it in the hands of someone who would appreciate it.

This was also sold as the "Sound-burger". It was my introduction to vinyl and was great as I didn't have a lot of room in my bedroom. That said, it was a very low starting point but thankfully I stuck with it. Truly bizarre, did they expect you to go to the park with your records and batteries, find somwhere level and out of the wind, expose records to dust and grit and play them?! Maybe they thought you could jog with it! I may still have it somewhere - if I have I'm setting up a group on facebook!

Why do you say 'very low starting point'?
It is not a toy, it is a transportable hi-fi turntable.
It has a decent cartridge and stylus, the preamp is also good.
It looks funny and is named like a toy but it sounds as good as a Dual 1216 with a Shure M75 or the Onkyo Y200.
