Weber AB200 black

This is a very unusual and somewhat overdesigned >200 watt custom tube amp. This amp has 6 x KT88 100s in the power stage, 1 12AU7, 1 12AX7, and 1 12AT7 in the tone stack, and an EL34-B in the rectifier position. It has a built in meter which allows you to bias each tube individually at your desired bias current as well as monitor the plate voltage (560 volts – beware). Other unique features are a tuner/mute pull switch on the volume knob. I don’t have an exact weight but it weighs about 40 pounds or so. 

This is an amazing amplifier and one that I am very sorry to have to sell. It is clean, both deep and bright, and very, very loud. Regrettably, way louder than I need. It does not grind.

I’ve used it to drive 2 Ampeg 4 x 10 cabinets, or a single Bergantino 4 x 10, or most recently a pair of SVT-115Es. It’s sounded great with all of them. Its configured for output from 2 – 8 ohms. 

I purchased this unit directly from Weber assembled. I had it subsequently modified by  Aztec Electronics of Watertown, MA, our local, very famous tube Amp guru, to correct the power supply to the built-in bias meter (the originally designed supply voltage for the meter was too high and caused the readings to jump around too much), and had a more efficient, quieter fan installed. Those six KT-88s generate a lot of heat!

The amplifier comes with a power cord, a custom padded cover, a second enclosure finished in white tolex, a second set of white round knobs, and a replacement set of two black screens. I can provide circuit diagrams in electronic form.

Shipping: Local preferred, but I'll consider shipping and packaging at your expense if you desire. I'm estimating about $100 for shipping and packaging.
