I have an Aikido 9 pin all in one preamp that I built and used for several years. I had taken it out of service when I started building SS class A amps (Pass) because I was afraid the voltage spike on the outputs at startup was killing the expensive JFETS in the front end of the amps. But It did sound great. Recently took it out of storage and noticed distortion in the vocals while playing. It sounds almost normal, nothing like a hiss or a buzz, but some garbling of the vocals is noticed. I'm going to open it up and check the power supply voltages, but I was wondering if this is symptomatic of aging/dying tubes.
Thanks,
Paul
