    Hi guys
    I am an Ampcoholic !!!!


    well just went yesterday to guitar center to pick up the LM an as soon as saw it something was out the ordinary , I had to put in the power tubes because the store that shipped sent it with the tubes wrap on bubble plastic, so went I was installing it , I notice that one of the tube sockets was just a little loose so I hesitate in turning up the amp or not but the guy a guitar center told me to do it because the amp has to fired no matter what !!

    so I notice a some noise but very manageable ( must be old tubes), so went ahead and put it in high power select the right impedance , fired up :

    channel 1 : fucking awesome , all the switches very good it covers a lot of ground , very nice clean channels I ever heard from a Marshall

    channel 2 : no fucking sound it did not sound at all . what a bump!!!

    channel 3 : very good : I liked everything it has something very superior that the TSl and JVM no question about it the bite , the tight low end , the fat it has all of it

    I did not tested the Midi part

    I have seen a few videos on you tube on repairs and seen some threads and it looks like the circuit on this head its a nightmare !!

    would you still buy that amp ? guitar center might send it to a tech but the tech that they have its no very good I took a TSl and they just didn't have any Idea of what was going on !!

    they might sell it for Clearence but i am not sure what to do if buy it cheap and send it to a tech myself or just pass and get another one!

    the price right now its a $800

    but i think they would goo as low for 500 as is !!!

    any help on this topic would be appreciated !!!


    Long life to the Marshall forum!!!

    The amp might be defective so send it back.
    It should have been tested before you bought it, but from guitar center I'm not surprised.
    There are a lot of similar reports about used gear from guitar center.

    I wouldn't trust a phukkin thing GC says. Avoid it! You'll be glad you did.

    However! GC does offer a 45 day return policy which covers used gear also. Take it to a specialist and have it examined. It will cost you also. ;-(

    Channel two uses 4 triodes, V2 and V6. If V2B or V6A-B are bad that can kill the sound output. Also there are push on connectors on the pc board, if the right one has disconnected or fallen off for channel two that will also kill the sound. If the channel switching is working the MIDI is working.

    May just be something simple.

    Yep check the pretubes first! As anitoli says that's simple stuff.

    There’s a lot going on inside a 6100,...

    I’d pass if it was me.

    Buy it given a return period. Try a new pre tube or 2 and I'll bet you got it made. The 6100 uses different pre tubes for each channel so it could bery well be a dead tube or goofy socket if 1 channel doesn't work. Too good an amp to pass up for that money.

    Now the million dollar question. What did GC charge you for the amp since you fixed it?
