Vintage power amp, capable of a massive 50w per channel of valve power. Made in the UK by the late Glen Croft, his products have a loyal fan base that keeps the Croft name alive. This particular machine uses KT88s and sounds simply stunning when powering the Yamaha NS-5000 or JMR Euterpe Jubile speakers. On the Sonus Faber speakers in my smaller room it's so smooth, you could listen for days without tiring. I have the matching valve pre-amp which I will list shortly in its own auction. There's a variety of valves, JJ KT88s, GEC, Mullard, all known brand names. With an output of 50watts per channel, there's more than enough for most speakers.
