Ain’t hifi fun? I’ve never had any noise issues for fifty years and last year my new integrated amp started to buzz loudly. Turns out my wife was using a space heater in the other end of the house.
All the best.
Need advice with clicking noise from my tube amp
I have a Don Sachs tube preamp and amp. Recently, I notice a consistent "clicking" noise, about 2 seconds apart, from both of my speakers while listening to my system. I don't recall the clicking noise changing at different volume levels. I swapped the Sachs amp for two other amps, both solid state, and there was no noise, so I concluded the issue was with the tube amp.
I took the amp to a topnotch tube tech who listened to it in his system for several hours and did not hear any noise, clearly not the clicking I heard. The tubes were checked and the biases is spot on for all four KT88's.
I asked Don about the possible cause and he is stumped if it can't be replicated with the amp in a different system. One possible thought was that the amp is picking up some RFI from some source, but I can't imagine what that source might be. I don't want to have to build a Faraday cage around my rack, as if I had the KSA's to do that.
Any thoughts from you folks would be very much appreciated.
