  • A little B-52 AT100 Porn

    I tore into it for the first time to set bias, I was impressed everything is tidy and secure. the only thing was the bias pot had some green glue on it, when I turned the pot it broke so now It will have external bias.
    Thanks to Charveldan for the schematic and advise on some mods, He's the man!!

    Thanks for the praise, my bias pot had that green threadlock too, don't trip, a good tech can have a replacement in no problem. The B-52's seems to be put together all in all fairly well.

      I had some mods done to mine a while back and the tech sent me gutshots while he had it on the bench. We were both impressed with the build quality considering it's origin.....

        By chance, does the board by the tone knobs say VS100-A?

        EDIT

        looks like it says AT100 - A

        My Madison Divinity has a similar setup, but the chassis setup is different

          I'm gonna try and put the pot in the rear accessible through a hole in the chassis and some tip jacks on the back for measuring.

                Let us know cause I'd like to Bias my amp without taking out the chassis and inverting it.

                    I had my tech replace the stock diode rectifiers with FREDs, and had him replace anything that looked like it was subpar quality while he had it open on the table. Other than the rectifier diodes, all he changed were a few caps (same value, higher quality).

                    Just got it back a couple of weeks ago, but I haven't had a chance to fire it up yet to see how different it sounds. Every time I've tried to take it for a test drive, the phone rings, someone knocks on the door, etc. Looking forward to putting in some quality time on it this weekend.....

                          Hell NO!!

                          I don't think they would touch this amp with a 10ft. velvet lined pole. It's got PCB's in it































                          I'm just givin' you **************** man. It was a stab at TGP. Cool thread. Not enough gut shots of amps around here anymore

                            I posted gut shots of the AT-100 in the gut shot thread already. Where's my medal?

                            It's strange. Mine has blue boards.

                            Check it.
