I am new to Massdrop and am looking for help. I got my amp 1-1/2 weeks ago and it has not worked since day 1. The amp produces a hum followed by a clicking noise about every 2 seconds through the right speaker. No other sound comes out from the speakers. The tubes do not glow nor get warm. I tried replacing the 6N4 with a new 12AX7 and replacing the EL34s one at a time with a new EL34. Same problem persists. Has anyone encountered this problem before? How can this be fixed? How can I contact APPJ to get help?
