Bogen DB-230a integrated tube amplifier untested Very Rare Read Description. Selling as found at estate. What\'s the very rare amplifier receiver. The knobs seem to function well. The faceplate is pretty clean. The top needs to be cleaned a little bit. I will let new owner do all cleaning. I did plug it in to take pictures. The front lights up and all the tubes. I did not test it any further. I will pack this and ship this extremely well. I am selling this item as is. AS-IS. Please look at pics and ask all questions before purchasing this item.
