SET for 88 dB 4 ohm loadspeaker

Tvad,

Thanks for the link. The amp shown is a parallel SET. It has two output tubes per channel, but it is NOT pushpull. Rather, the two tubes are hooked up in parallel. Not only does this increase output, it lowers the output impedance of the amp.

I know there are a lot of SET purist who say that configuration does not work well. I have no idea if the drawback of this configuration outweighs the advantages. What I can say is that my amp (Audionote Kageki) is a parallel SET (2a3 tubes) and it sounds great to me.

oops, I meant Mastersound 845 Ref. As a banjo player, I think about the Gibson Mastertone whenever I write mastersound.

100Watt SET???? Something doesn't smell right here...

The KR Kronzilla DX monoblock has 2 T-1610 Kronzilla tubes in parallel for a total output of 100Watt SET. Here is a review: http://www.enjoythemusic.com/superioraudio/equipment/0506/kr_audio_dx_monoblock.htm
The Kronzilla SX and SXI stereo versions output 50W each.

I own the NAT Audio Symmetrical preamp and the SE2se power amps. These are one of the most incredible sounding products I have heard in my life. Well worth the money.
