Miller and Kreisel MK MX-100 Very low audio - M & K - Miller & Kreisel M&K MX100

A Miller and Kreisel sent to me with the complaint of very low audio. I should have just tested the ESR of the caps first because you guessed it. Someone had replaced one of he caps with a cheap generic cap and that was the issue. It got all of the amp board caps replaced with good quality Panasonic caps.
