For this amplifier you will have to be VERY carefull when buying new KT170 tubes ....current production is off variable quality , only buy from a reliable source with garanty.....these kind of tubes are also only made by one manufacturer ! ( in french they say : "un marché prisonnier " ) I like Jadis since and worked on them as well as tuned them for more than thirty years but I would never buy an amplifier witch uses those kind of new production tubes only .... Best is when buying an amplifier to buy and stock tubes for later service at the same moment and at todaysprice and disponibility ! ............a quad means not 4 tubes but five matched ....one can always go bad and without a spare tube you are in for a total new quad..... kind regards @@vinylseeker867
