laxman Posted September 20, 2007 Share #1 Posted September 20, 2007 Currently working on the TCI, wondering what the transistor specs are since the markings are gone. Appreciate any help. Link to comment Share on other sites More sharing options...
mbrood Posted September 20, 2007 Share #2 Posted September 20, 2007 I think THIS is a bit more what they should look like... not sure of the manufacturer but print it up and take it down to an electronic component store??? ETD41-035 This is an umodified TCI... like yours, those grey (balloon) diodes need to come out and be replaced with 1N4007 type for durability. http://www.bergall.org/temp/venture/tci1.jpg Link to comment Share on other sites More sharing options...
laxman Posted September 21, 2007 Author Share #3 Posted September 21, 2007 Thanks Mbrood. Interesting the transistors and most of the internal parts are the same as a Yamaha Vision TCI. http://www.jetav8r.com/Vision/TCIRebuild/TCI_Rebuild.html Link to comment Share on other sites More sharing options...
pegscraper Posted September 21, 2007 Share #4 Posted September 21, 2007 Are these things potted in epoxy? How did you guys get the epoxy out to where you can access the circuitry like this without damaging things? Link to comment Share on other sites More sharing options...
mbrood Posted September 21, 2007 Share #5 Posted September 21, 2007 Mine is shown EXACTLY how it came out. The only "potted" component I have run into was the pressure sensor and it's full of some gummy compound that picks out "fairly" easy. Link to comment Share on other sites More sharing options...
GeorgeS Posted September 22, 2007 Share #6 Posted September 22, 2007 I found this Cross Ref: http://www.jetav8r.com/Vision/TCIRebuild/TCI_Rebuild.html Fuji, ETD41 use --- MJE5742 MJE5740Specs.pdf www.Digi-Key.com Or --- NTE2317, nte2317.pdf Not sure if this is good information. But worth checking into . Also, do Google Search, " NTE2317 " This one apparently is still available, If sombody can find Spec sheet for this one, and the ETD41035, and do a detailed comparison. ?????

mbrood Posted September 22, 2007 Share #7 Posted September 22, 2007 Now THAT'S what I like to see, a few guys checking around and we end up with replacement parts for our old beasts. Thanks guys! I'm certainly noting the cross reference. I wonder if there's a repair center for the Yamaha Vision TCI that would work on OUR TCI units! Link to comment Share on other sites More sharing options...
