For your pleasure (or disgust); a nasty 2238b. I picked this up six months ago and so it's sat, sealed in plastic on top off the pile. Space opened up in my shop so I decided to unwrap and have a go. My best guess is this belonged to a giant loose bladdered chain smoking cat who enjoyed sitting on the receiver while entering flavor country. I grabbed the dim bulb, hepa vac, modified wet/dry, nitrile gloves and got to work. I'll dry vacuum then wet clean and vac the remaining. If this gets components replaced I'll probably just tear it all down and re-clean everything individually. -It's missing the input selector knob, preamp jumpers and it really stinks of urine and tobacco. -Powered on it comes out of protect. -I should've worn a respirator while opening up the case. -Corrosive glue? Urine's even worse. More shaky phone pics after the cleaning.
