I am selling my second Aguilar DB728 400 watt tube power amp. This unit is in excellent condition and works perfectly. This DB728 has eight new, matched Winged-C 6550 power tubes. Amp is biased and ready to go. Pair this with a great preamp and it is an SVT killer! These suckers went for over $3000 new!
