I am selling my B&K PT-3 pre-amp. This is a 2 channel system that I have had in my bedroom since I first purchased the two components. I am the only owner of this equipment, as I stated it is in my bedroom, no smoking, no pets. About six months ago I have the pre-amp serviced and cleaned up from some dust settling inside the device. The power light would flicker on occasion, that is what prompted me to have the unit cleaned and had the lamp replaced. I would of rated the piece higher but did not want to violate the rating scale provided by Audiogon.
