400W of pure bass power deliver an enormous, fat, warm sound!

8 - 6550 vacuum tubes are at the heart of this amp. Ultrawide frequency response is accomplished through the use of a specially designed toroidal output transformer. It's built for the road and has a reputation for extreme reliability. Features include 2 sets of speaker outputs in both banana plug and 1/4" configurations and a preamp thru for hooking up multiple power amps. The DB 728 has a "soft start" for the regulated screen voltage, a feature found only on the best audiophile amps. 2 large whisper-quiet fans keep the amp cool and have high and low speeds for nearly silent operation.
