Mariano, Bedini makes solid state amps only, so you'll have to look elsewhere for a "KT88 vintage" (KT88 is a tube). I don't know what you mean by "vintage", but there are plenty of nice new amps that will run KT88's, including the Music Reference RM-200 Mk.2. (currently included in Stereophile's Recommended Components list, if that matters to you ;-). There is one offered on Audiogon right now for $2400, a great deal.
