RE: PPPUL EL84 Amp...Does one exist?

Mike,

LL1660S are used for the IT. I configured the primaries SE (all in series)to get the most H possible. Those are 47uF Solen power smoothers, 3 per channel.

The OPTs are Lundahl LL1682s, this iron is similar to the LL1663 only 5.5 K primaries and 5 ohm secondaries.

I applied feedback from the secondaries of the LL1682s to the cathodes of the output valves. I'm using a single 6h30p with it's own filament supply as a driver for the LL1660s primaries.

I tried to run this amp Pentode without UL feedback. It had a very engaging sound but the distortion levels were prohibitive. I tried UL and it cleaned it up to good levels without messing the sound up.

I will clean up the schematic and post it.

Thanks Stuben
