Harvey Rosenberg: Did he or didn't he......

have anything to do with a company in the 1970's called "Tube God" based out of Croton-On-Hudson, New York ? I think that he did, but i'd like confirmation from someone that knows for certain. Sean
believe so. Know he worked with Futterman on the OTL designs.
Yep, been there, but it was the mid eighties....Bought some speakers from them which used Strathern ribbons and leaf tweeters.......Harvey was the Tube God and the place was an industrial park built like a bomb shelter....
Yes, Harvey was the Tube God. I talked to him about possibly buying some Futterman amps in the mid 80s, and he personally answered the phone by saying "Tube God". I didn't buy the amps, but I did think they were cool.
I also had the pleasure of visiting the Tube God's headquarters. Puchased one of his first preamps. Sounded very good with the Futterman OTLs and Quad 63 I was using.

No one was more passionate about audio than Harvey.
Thanks folks. After re-examining the paperwork that i have on these items, one says 1981 and the other says 1983. Nowhere in it does it mention Harvey although there are a few other names brought up. Like i said, i thought that he was involved but just wanted confirmation. Sean
I have a Tube God NB-1 phono preamp that was made by Harvey and the gang. I had some conversations with Harvey and he certainly did go by the name Tube God.
Just to set the record straight-er, Harvey was certainly a patron of Julius Futterman's, but Julius patented his OTL circuit in the very early 50s, probably before he ever heard of Harvey.  Later on, Harvey and/or New York Audio Labs, the company NYAL, may or may not have paid Julius some money for the rights to sell their OTL amplifiers which used the Futterman output stage, but Harvey almost certainly had no part in collaborating with Futterman design amplifiers.  NYAL had an excellent engineer named George Kaye on the staff.  Mr. Kaye made some mods to the Futterman design that were said to improve bass performance and maybe the capacity to drive low impedance speakers.  Harvey came to be associated with those mods via his close connection to NYAL.  But the brains belonged to Julius in the first place and George Kaye at NYAL. This is more or less the story from where I sat. Harvey was a funny, clever, and certainly very smart guy who understood marketing, but I do not recall that he was a circuit designer in a primary way.  Yes, he was the self-styled "Tube God".
I remember seeing Harvey walking around CES with his kilts and tubes surrounding him like a belt. What a character.

"Harvey came to be associated with those mods via his close connection to NYAL". I'll say it was close---Harvey owned NYAL! In his search for the best amp for his Quad loudspeakers, Harvey learned of Julius Futterman and his revolutionary and radical OTL circuit. Harvey discovered Julius was living right there in Brooklyn, and befriended him, becoming his best friend and confidant.

Harvey knew circuit design, and the two of them started working together on solving some of the Futterman OTL circuit's problems (it was, amongst other things, rather unstable, exhibiting a lot of parasitic oscillation). When Julius' deteriorating health made it clear he would soon die, he sold the rights to the Futterman name and the OTL design to Harvey, who subsequently started NYAL to manufacture and market tube electronics. It was only then that George Kaye was hired by Harvey, who worked with Harvey on continuing the improvements to the Futterman circuit. George was largely responsible for the design of the NYAL Moscode products, which incorporated mosfets and tubes in a hybrid design, Harveys way of bringing tubes to the masses. 

The NYAL Moscode 300 was my intro to tube electronics.  Yamaha C-2a pre-amp, Dual tt and Vandy 2Ci speakers, ca. mid 80s.  I had George Kaye modify it after NYAL went under,  Scratched my musical itch for about 10 years or so.
