just bought a pair of cary 300 SE signature mono block and love the way it sound.The Problem is that I dont know how to manual bias that this amp require and I can not keep the same pair of tube in an amp for more than 2-3 days.This pair have a perfect gold face-plate and is in excelent condition.The JJ 300B have about 5-10 hrs on it and 2 pair of 6sn7wgta have plenty of life left.I am open for trade with other 300B mono.must be auto bias and I can add a little $$ to off-set the deal..please email a contact number to ttrhp@hotmai.com if interested.it'll be on audiogon within the next few days and you can check my feedback on audiogon under the same name.I am asking 2k for it and price is firm.thanks
