Purchased from Tom Lee's rental stock in 2009 or 2010. Not sure of the year of manufacture but must be 2002 or earlier as it is US-made rather than Mexican-made which came post 2002...The amp is not cosmetically perfect (rental stock...) but has been professionally used, maintained and works as it should. Comes with some spare tubes and a channel selector switch. Amp retails new at L&M for around $1,000. plus taxes. Please see link below for info/specs.
