EL84 output The AA-151 is one of the best sounding tube amplifiers I've heard and has just sold but luckily the AA-21 solid state amp showed up just before I shipped the 151 out so I could see them both at the same time. and includes the optional tone control features that many of the AA-151 weren't built with
