WANTED - Futterman H3 as a project
« on: 7 Oct 2019, 04:58 pm »
Looking for a Harvard Electronics or Tech Instruments (Futterman) H3 OTL project. Most are quite old and need a complete rebuild. I am interested in doing a project like this. If you have an old Futterman H3 in good cosmetic condition, but inoperable due to age and the ravages of time, it might be of interest. No point in letting it linger in storage - it will not self-heal, I am looking to bring one back to life and enjoy listening to it in my system. Willing to put in a lot of work to get it operational again because I would like to hear one in prime condition.

  • To whom more was given more will be required.
    • Never go to a psychiatrist, adopt a straycat or dog. On the street they live only two years average.

I was an EE in an earlier life.  Summers at school I worked in a mil-spec soldering shop.  Did some development work as an EE, including building prototypes. Unfortunately when I went to school it was discrete components, with no tubes or transformers.  Would have enjoyed that education. 

I actually enjoy the details, which I think are the most important part of a rebuild project.  The Futterman has an interesting, old style power supply configuration.   Point-to-point wiring makes life a lot easier with regards to replacing components and fully rebuilding something - old circuit boards get lifted traces unless you are very careful and even more lucky.

Likely lots more time will be invested than will ever be returned in $, but I am retired and my time is available to use as I enjoy.  Not a bad thing. 

I think the hardest part is going to be finding the starting point Futterman amp......

It has been over a year since I was at an audio store in Indianapolis called Tone Studio.
At the time he had a pair of Futterman amps but I don't know what model or functional status.
I didn't know what they were at the time but he said something to the effect that he wanted to sell them to someone who really knew what they were.
He's a reputable guy and has had a store in Indy for decades.  I bought some speakers from him in the past.  good luck
