Back in the Shack: 1960s Harmony H400 3w Tube Amp

I had this for sale for a while in the shop but pulled the listing (to troubleshoot) when I thought it had a short somewhere. I was wrong -- it was the socket I had it plugged-into that was at issue. I've been using this in the house for practicing since I found this out and now it's back up for sale -- I'll be listing again soon. Check out its blog post here...
