The best tube poweramp. . What do you think about ?

I have NY Audiolab Futterman OTLs. Rarer than hen’s teeth. Easier to find than the ones built by Julius, which are rarer than rocking horse s^#*.

Jon Specter, cousin of Al Kooper and former NY Audiolab technician, converted them from pentode to triode for me, upgraded all the caps to Jensen foil oil audiograde with help from George Kaye of Moscode, also a NY Audiolabs alumni.

I drive a pair of very efficient Altec Lansing 604Cs, (I rebuild them every 10 years, I have a choice of 8 or 16 ohms, I keep them at 16 ohms at Jon Specter’s recommendation), 101 db efficiency.

I couldn’t be happier.

I can find you a pair of NY Audiolab Futtermans. PM me.

@lukaske You have a real winner there. The VAC phi 300 would be one of my top picks. Even the VAC phi 200 is very good.....Jim

Thanks a lot , to all of you !

Old amps like Futtermsn judt asking for trouble their problems were many 
yes they sounded good but tons of unit failures. Look for a modern amp  like Ayon for example transformers are the heart of the unit , Ayon use world class Lundahl for transformers and chokes,
And  micro processor controlled to monitor each tube for optimum operating range ,then auto bias just adds more resistors in the circuit and averages all tubes in sum too much wasted energy , and no cheap sheep metal that vibrates 
thick aluminum chassis even the tube sockets are gold over solid copper ,most are cheap brass.
the spirit3 highly recommended.
