Sonotone 9TAHC Repair (audio drop outs)
I have a Sonotone 9TAHC installed in a Garrard AT6 MKII. Occasionally when playing a record the signal from the cartridge would cut in and out.
I though that the stylus was at fault, so a brand new one was ordered. Unfortunately, this did not solve the issue. I noticed that if some gentle pressure was applied to the headshell the audio would come back.
This convinced me that the cartridge was at fault.
I removed the cartridge from the headshell and was easily able to remove the metal surround from the cartridge body.
At this point the 'rabbit ears' and ceramic elements can be withdrawn from the cartridge body.
The elements were filthy and were gently cleaned with Autosol.
Once everything was back together the cartridge worked fine without any issue.
I don't consider this post a comprehensive guide to solving this issue, it's more of a proof of concept.
