VFE Tractor Bean vs Enterprise parts comparison
« on: October 13, 2021, 04:23:28 PM »
Fellow DIYers:
I received two Tractor Beam pcbs from Brian the other day (in a timely manner, as always). The first Note in the Tractor Beam build document states: "This project is built on the 'Enterprise' PCB... with a few modifications."  I'd be very interested in learning what those "modifications" were.  I've searched for the original build documents (and Bill of Materials) for the Enterprise, but have been unsuccessful finding them.  My question for any readers of this thread is: Does anyone have the original documents, including the schematic, for the Enterprise circuit?

Based upon audio clips I've been able to find, I still prefer the sound of the Enterprise, so would most like to build that circuit.  I realize that sound is very subjective and that much depends upon recording techniques and quality, but I've just been less impressed with what I'm hearing from the Tractor Beam circuit, as compared to the Enterprise circuit.  Be that as it may, any help finding the original Enterprise plans would be greatly appreciated.
Thanks

If I remember correctly the name change didn't happen at specific version but he just decuded to change it. I think the name change happened shortly after the v2 circuit where the Depth knob changed to Center, and the middle PV mode was introduced. I have an "Enterprise" with those changes and I've seen some others out there that do but the overwhelming majority don't.

Funny thing is, I think the schematic in the MB build doc is for the pre-v2 "Enterprise".

I don't think there is anything that was changed in the circuit that would change the sound that much. The part values used were likey tweaked over time, so that may be more if the difference you are hearing.

More info here:

Edit: There are seperate V1 and V2 schematics as a part of the file bundle here:

And it's included in the larger bundle here:
