Regrettably having to sell this fantastic amplifier due to my changing finacial situation, its 18 months old with upgraded tubes now comes with TJ Full Musical 300Bs a massive improvement, also Tungsol and Mullard power tube upgrades, an extra £350. The unit is in mint condition fully boxed with manuals and warranty card. The amp is a power amp with volume controls so can be used as an intergrated if required, it sounds pretty damn good either way. Looking for £2795 which considering the new price is £6500 without the upgrades a real bargain me thinks.
