After building a S.E.X. I wanted to build a Seductor. Unfortunately, I missed my chance to buy a kit so I bought a used Seductor. Although it wasn't apparent in the pics, the amp had some wiring issues. There were several burnt wires, a couple charred resistors and a beat up tube socket. The amp worked, but if the right channel input tube was bumped or not inserted just so, the amp would emit a loud crackle, very disturbing.
Bottlehead was kind enough to provide the parts (very reasonable cost) to replace the input tube sockets as well as several resistors connected. I will say I believe it's easier to build the amp as a kit vs rewiring as removing parts is sometimes messy. After finishing I ran the recommended tests with excellent results.
Listening now and really impressed. The amp is dead quiet with no signal applied and sounds beautiful with music.
