I won this 4400 a few months ago, seller said everything worked, just needed some TLC. Sure looked nice in the pictures, working scope and all. That's until it was poorly packed and damaged in transit, 1" total of bubble wrap surrounded with air pillows don't cut it for a 4400. I noticed a bent corner on the faceplate, and a couple crooked feet. Did a quick internal inspection, didn't see anything too amiss. I powered it up on my DBT, none of the dial lights came on, and soon after, R812 on the power supply let out the magic smoke. Found the damage to the chassis upon disassembly, the area around the volume pot is crushed in about 1/16". I'd assume something is shorting out in there to cause R812 to burn up. That's as far as I've come, further diagnosis is in the near future. Always wanted a black faceplate 4400, I'll have the opportunity now since the original faceplate is warped badly. I'll have to pull the front part of the chassis to straighten it. Figure out why magic smoke is escaping, fix that, then on to restoration. It's a tall order to take on this mess, I haven't done a resto for over 3 years now. Stay tuned for fun and games!
