Horning Perikles w Frankenstein amp

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.

My Frankenstein amps have absolutely no problem driving my Coincident Pure Reference speakers with 2- 12 inch woofers per speaker. Every now and then, I will switch out the Franks and plug in my VAC 30/30 but the Franks still rule in my system and to my ears.

Charlesldad- Good idea but the Wavac is long gone (but I do see it still floating around A'gon land, it's distinctive by the dimple on the back of one of the transformer housings). I guess my system page really needs updating. Thx for the thought, tho.
