Horning Perikles w Frankenstein amp

Michael, you may actually own the Perikles Reference, with 2 12" woofers on the rear.

Personally, while I do like this amp a great deal, I would be skeptical of any 300B SET amplifier with these speakers. That said, Jeff normally produces phenomenal (IMO, best of show) sound at the myriad venues he displays, and I think he may have used a 300B(?) based Tron amplifier. Folks have assured me the Border Patrol amplifiers, with their novel choke input power supply could do the job, but when hearing them with smaller woofered loudspeakers, I remain skeptical.

In my experience of living with them, despite the Lowther midrange, these Hornings work best with a surprising amount of power. Nothing against the 300B, as it's certainly a beautiful sounding tube, but I find it too soft on the low-end to get the Hornings to sound right. In my opinion, you need an amp with a pretty stiff bottom end, otherwise, the Hornings come off all wrong. If you don't use an amp that takes control of those woofers, the bass goes MIA, and the overall sound is quite unbalanced.

Best amplifiers I've used with them: 15 wpc Deja Vu push-pull 2A3, a Chinese 30 wpc push-pull transformer coupled 6AS7G, and 60 wpc Jadis DA60. The DA60 might surprise, but the speakers really loved the power, while 30 wpc Jadis DA30 and 40 wpc Jadis Orchestra Reference were not good matches.

Trelja raises a good point and mentions reasonable alternatives. No amplifier does everything (there's always the reality of compromise regardless of what you use). Some 300b SETs have better drive and control than others, High Water Audio demonstrates Hornings with 300b amps sometimes, see what he advises. I could see a DHT push pull being a very viable alternative. I don't know how much Hornings differ from the Coincident speakers in terms of ease of drive. The Frankenstein drives them pretty easily with good bass and woofer control. I've always been curious to hear the Frankenstein with the Hornings, Tonian Lab and the Ocellia speakers.
Charles,

Charles, I had the pleasure to hear the Musical Affairs Grand Crescendo's in an NYC Apartment. I could be very happy with those.
Swampwalker, I realize this does not answer your question.

No problem, Iso.
To all, right now I am using Doshi-modified Lectron JH-50 (60 wpc 6CA7 push pull). My VAC 30/30 (30 wpc push pull) has a fault so it's temporarily on the sideline. I've been curious to hear what the buzz about the Franks is all about. In NY this spring, I was very impressed w the Dragons driving Israel's top line speaker but those are out of my price range so I thought I might give the Franks a try. Just trying to feed my curiosity/habit w/o going broke.

Swampwalker,
Do you still have the Wavac MD 300b? I realize it`s approach to power supply and circuit is different from the Frankenstein. It may still give you some idea of compatlbility with the Horning.
