content: hi guys hope i am in the right section for postingi thought i would share one of my protectsi was asked to build my mate a valve guitar amp so i decided to build every thing from scratch2 6v6 push pull and 2 6ln7 pre and phase inverter and 1 6sl7 for the reverb tanki made the electronics point to point on plexiglass using smell self tapping screws and soldering on tophere are the pic and the circuit lay outhttps://www.flickr.com/photos/127793137@N02/

content: You actually used CrapXcon electrolytics? I didn't even know those POS can be purchased other than by Chinese mass producersWhy not go for Rubicon or Panasonic or something like that from your distributor, especially for a custom one-off like this.ETA: also - where are the valves?
