Well as much as I luv this little amp I'm afraid I need more power at certain times and might have to move up the Decware chain sometime down the line. So I'm selling my mint, barely 2 months old Super Zen. Amp has the "b" transformer (6-16 ohm) and gold volume knob, smooth not stepped. Original tubes and double box. Can send pics if needed or check Member's Systems Pic Gallery/Rockn.            $ 775.00, split shipping, I'll cover Paypal. Thanks
