For example 2SK1058/2SJ162 (formerly manufactured as 2SK135/2SJ50 in TO-3 case) by Hitachi.

does somebody knows which manufacturer of high quality audio amplifiers uses (if anybody is using them) lateral mosfets...

manufacturers like Mark Levinson, Krell (well, i know Krell is not using them but) and not manufacturers like Hitachi, Renesas :))

The Saint - Aussie amplifiers is a nice guy but not a professional making manufacturer - he is a designer and is selling boards, kits and so on ...i value him and his professional work a lot - but he is not a manufacturer like Levinson and Krell for example... i was thinking about a manufacturer......

"Hi-End at low cost"

If "low cost" is not questionable...

JE Sugden used to, but don't know the current range.
Michell use FETs and I guess they are NOT verticals.

I used to have Monarchy's SE100deluxe monoblocks.
Hitachi 2SK1058/2SJ162, if I recall well, 8 units total as output devices.

I think their new SE-250 hybrid amp uses 12 units :cool:


PS: you can mail the CEO asking for info. Mr CC Poon is comunicative, in a laconic style... :D
