    Hey,
    I have a cpl heads needing work, and I have a couple questions. First, can anyone recommend a good tech to do the repairs in the Chicago/Joliet area, with a phone number if possible. Second, I have a Marshall model 4100, a 5881 based amp that I know has a bad power tube. I would like to know if it is possible to use KT66 tubes in it. I'm not sure if the amp can accomodate the actual size of the larger bottles, and also, the amp has a 1/2 power switch that goes from pentode to triode (I think) and I'm not sure if the KT66 are compatible with this.
    As always, thanks for taking the time to read and reply, and for sharing your wisdom!

    http://www.britishaudioservice.com/ - they are in Sugar Grove. I have not used them personally - but, they have a very good reputation.

    My luthier for my guitar work is Rick Cremer of Cremer Guitar Works in N. Aurora. He has a good amp guy there as well.

    There's also a good amp guy named Joe Campagna who works out of his house - Guitar Technical Services. I have used him before and he's fantastic. He's in Clarendon Hills. He can be contacted through Tobias Music - http://www.tobiasmusic.com/

    I don't know if KT66s will fit in your 900. Somebody else here may.

    Groovey,
    Are you sure they won't fit? Do you own a 4100? Could I run 2 KT66 and leave the other two sockets empty?
    Thanks!

    Vaacheck Don't misunderstand, it was a play on words. They may fit, I don't know?

    Sickboy said he didn't know if the tubes would fit maybe somebody else would.

    I said nope I won't fit ! Ha Ha not so funny the second time

    Just call Tim and ask

    Sorry about the bad Joke
