On the second Kloss 88, which I bought from a different person on Ebay a couple months ago, all was well until a few days ago, when the Left channel or speaker got very weak. Or at least he thought he had, because the problem was always intermittent, and would often recover temporarily on pulling the plug and restarting again. I sold it on Ebay for parts, and the guy who bought it said he replaced the subwoofer and solved the problem. I've had two of these radios, the Kloss 88/ On the first one, the Left channel went out. If anybody here can come up with a schematic for the Kloss 88, I would be more than glad to share with the community the step-by-step details of my experience in repairing these five radios.Ĭlick to expand.I've looked for a schematic, too, but can't find one.

I was very surprised that the company would be completely unwilling to part with documentation to a service professional and made my decision to move on and not support a company which will not support its products with repair documentation.

I would certainly have bought the newer offerings at the time as replacements if the Cambridge SoundWorks had shown good faith in supporting the earlier equipment. It's really a shame to have a radio of this quality be junk because the manufacturer won't part with service documentation. I will be happy to help all with this if somebody can come up with the schematic. Whatever the cause, it certainly seems to be inherent in these radios - at least in a range of production. It's also possible that there is a integrated circuit related to the front panel control which has shorted internally between the signal layers - in which case an IC replacement might be all that is needed. The problem could be as simple as an intermittent physical connector between two circuit boards. I have enough failure data from the different radios that if I had a schematic I could show exactly where the problem must lie - but no such luck with the schematic. What this likely means is a stuck digital control bit. Some of the buttons seem to either not be working, controlling the wrong feature or trying to control two unrelated features at the same time. However, the failure which ultimately resulted in an unusable radio in each case seemed to have the same cause in each case - the functions of the front panel controls gets scrambled. The intermittent booming bass was always the ground to the rear panel inputs - a definite weak link but no big deal to repair. In any event, the 5 of 8 all failed with similar characteristics. I don't recall whether these were quiet at idle in their early days. They provide excellent near-field sound but the slight+ AC hum when not masked by sound reproduction can be annoying at this distance from the radio. The remaining three but still work as bases for my computer monitors and multichannel sound for the computer. I've had 5 of 8 of them fail (three of which were purchased as refurbs) and was unable to locate a schematic or find any assistance whatsoever from Cambridge SoundWorks when I devoted myself to the task a few years ago. I would use a 2W FM transmitter on an available FM frequency and place these around the room, optimizing the audio levels for each location. I have eight of these which I previously used for unobtrusive occasional medium level sound reinforcement for very small venues - for which they were excellent.
