Coincident Frankenstein mk.2 amps

Hi tswisla,
The Truth of the matter is that there’re no bad choices on your list as all are excellent options. Each of them will have their positive attributes and distinct signature. I believe that you’ll be very happy with the Psvane Acme but I also believe that you’d be very happy with any of them.


It’s good to have such wonderful choices available for the superb Frankenstein mono blocks, Congratulations on your selection and I look forward to your listening impressions. It’s good to know that the Frankenstein and Zu Soul Supremes pairing is so successful for you.

After wanting them for a very long time, I'm now currently awaiting a pair of Coincident Frankenstein MKII's to appear for sale in Audiogon, or one of the other used audio sites online. Sadly, a serious family medical emergency that thankfully ended well, took me out of the loop for a few months (late December through mid March) and I just missed out on at least four that I would have snatched up instantly. Now its just a question of waiting. The only currently available option is is a pair of MKIII's being offered in a forum, whose owner has an extremely overpriced opinion on what they are worth. And while a MKIII would certainly be optimal, given the average prices for the MKII's, it would be hard to pas on one of those. Hopefully a pair in excellent condition appear soon. 

Thanks to everyone who has contributed to this discussion as you have provided invaluable insight into tube options for the Franks, which I was searching for, and truly appreciate. It is good to see some notable online audio forum contributors perspectives, in particular. Thanks especially to Charles1dad for your always well considered, insightful and kind thoughts which I have greatly enjoyed over the years in various discussions. And in this instance, on the Franks, in general, and your extensive tube experiences. I hope to be joining you as an owner soon.

Hi JC,
Thanks for your kind remarks.
I’m pretty confident you will be happy with the Frankensteins in your system. At first listen to my new Franks in August 2009 I knew I’d made the right choice. Now nearly 12 years later that feeling has only grown.

@nightfall Good luck on the search! I followed Charles' advice as well and loved those amplifiers too. 

Also, I haven't heard a mkIII, but am somewhat sceptical that there's much difference between it and the mkII model.  I suspect the primary difference between the two is the price. 

Hi Cal,
10 years elapsed between the introduction of the Frankenstein MK II and the upgrade to the MK III model. Israel Blume was always very proud of the part quality of the MK II particularly the Japanese made double C core output transformers.

The MK III is said to have even better output transformers, power supply capacitance and other parts improvement. I have no reason to doubt these stated improvements. I can however say the MK II is a marvelous SET amplifier and a tremendous value purchased used.

With money saved buying a used Frankenstein MK II, one could (If so desired) purchase upper tier quality 300b output tubes. With the appropriate speakers, one would have the foundation of a superb sounding audio system.
