  • schematic and bias set up info for trace elliot AH350SMX MOSFET power amp

    i have trace elliot gp12smx head,thats what it says on front but rear is AH350SMX confusing to say the least
    can find nothing schematic wise that indicates the use of hitachi 2sk1058 and sj162 mosfets,i need to know
    bias set up,and what else is likely to of failed in the driver stage,does the bias control transistor generally fail it
    seems to make sense in changing the electrolytics,i have spoken to someone who has had many years experience
    with these and the awful bipolar b as he refered,does anyone have any experience of instability probs as i am informed
    a major issue with the vers i have here thanks steve

    Steve - have you ever heard of punctuation? I'm outta breath reading that!

    I can't answer your question but here's the service manual, if it helps. trace-elliot_GP11-AH350-AH500-MK-V-BASS.pdf
    Experience is something you get, just after you really needed it.
