Hi all,

Does anyone have a photo of the inside of GFA-6000 5-channel amplifier? I want to see a picture of internal construction prior to making a decision on whether to buy this amp or not.

Thanks!

    Does anybody know where I can buy a service manual for this amplifier? I looked at all sites that sell manuals and none have this one.

    Thank you!

    Anything in particular you want to see? I may be able to get you one before I leave town. But I should be able to get to it next week sometime if you can wait that long.

    Got the manual from Adcom already. Thank you very much for the offer though!

    Just wanted to say wow!

    I remember why I sold the GFA-5400. It sounded very metallic and bright with my RT1000p speakers, although it was driving them very nicely overall.

    The GFA-6000 output stage is BJT based (compare to 5400, which has MOSFET output stage). The sound is full, rich and much warmer than 5400. It really compares well to my current Harman Citation 24. Definitely looking forward to A/B the 6000 vs. Citation 24, and eventually vs. Carver TFM-24 (which also uses BJTs in the output, but which is much more powerful than the other two).
