īeware it is an (unacknowledged, hidden in plain sight) flying rails amplifier.
You need a cranked up Plexi style amp with the Tube Driver, Echoplex, reverb, and optional compressor.

Joe is 100 correct about the voilin tone. I have the 3 knob Tube Works/BK Butler model like what Andy Timmons uses. Redo using your actual measured voltages.īased just on PSU specs, but like Enzo once said, " the amplifier is just that thingie between power supply and speakers".ĮDIT: that´s some minimalistic power amp, just 1 Op Amp and 2 MosFets. That cool Joe, I also prefer a lower gain NOS preamp tube in my Tube Driver. Tube Works 910 Tube Driver (3 knobs) Tube Works 911 Tube Driver (4 knobs). * 4 ohm load: 40*0.5=20V RMS, meaning some 100W RMS Audio Matrix Mini Matrix (same pedal, new name: Mesa Boogie complained about the name). * 8 ohm load: 40*0.6=24V RMS, meaning some 72 W RMS
#Bk butler tube driver chandler schematic manual#
I have one of these with blown output, anyone have a schematic? Also, does anyone know what the power rating is? I found one place that says 40w, but can't find anything definitive, even the user manual says nothing about it.On unknown SS amps, you can estimate power :ġ) measure main voltage rails, as an example, say,+/-40V DC.Ģ) multiply that value by 0.6 if loaded with 8 ohms, by 0.5 if loaded 4 ohms, that will be very close to output RMS voltage, then do the Math, say:
