Piano, Organ, and Keyboard/cleaning Thomas Palace III 903

Question
Hello,

My son just acquired a Thomas Palace III 903 organ.  It works pretty good, but needs a good cleaning (the speakers hum).  Just wondering if there is a good way to clean it and get better sound quality.

Thanks

Answer
Hello Dawn!  The most common cause of hum in older organs are the electrolytic filter capacitors in the power supply and amplifiers.  When they age, they begin to deteriorate particularly with non-use.  These really need to be replaced so they don't cause damage to the rest of the circuitry. The other cause of hum is a compromised ground (commons).  Cleaning would not fix a hum problem and may actually cause damage to the circuitry due to static charges that can build up and damage sensitive components during cleaning...particularly when using a standard vacuum cleaner. Taking the organ outside and blowing the organ out with compressed air may be a better choice.     

Someone will need to determine which situation is causing the hum.  Unless you know someone who understands proper repair sequences and component replacement procedures, correcting the problem is unlikely.  Check out the following website:
