Hello Pioneer guys. I usually dabble in the tube world but a friend brought over a Pioneer model A717 which has at least one issue, a steady pop, pop, pop on the right channel after 10-15 minutes warm up. I checked DC offset at 2mv on the left and -9mv on the right but beyond that, I'm a little outside my comfort zone here. Any advice on what to look for? There does not appear to be any bias/offset adjustment pots so I'm guessing that's managed by ICs on the amp board.
Thanks in advance for any help you can provide.
