Inherited this from some guy that I bought a load of stuff from. It has Mullard 510 written on it. Haven't a clue what it is so I'm not saying it is a 5 10 spec but it looks like it has some interesting components. Has some mullard tubes in ez81 el84 ecc83 and ef86. Don't know anything about this set up. Not the sort of thing I would want to get involved in as the wires and sockets look ancient and weird. Just put your offers in if you think it's worth something. Be realistic as other people will be offering so I'll see what comes in. You are buying for parts not working based on pictures
