Rob Mitchell Posted November 3, 2015 Share Posted November 3, 2015 For this circuit I found: Transistor PNP 558 = NTE159 Transistor NPN 548 = NTE199 = 2N3710 1 Quote Link to comment Share on other sites More sharing options...
R.Cade Posted November 3, 2015 Share Posted November 3, 2015 That's complicated for a video amp circuit... Normally you only need one transistor. Is the Odyssey signal extremely weak? Quote Link to comment Share on other sites More sharing options...
mtshark7 Posted November 10, 2015 Share Posted November 10, 2015 Yea man what R. Cade said. I use this one...see attached. Sent from my SM-G900V using Tapatalk 1 Quote Link to comment Share on other sites More sharing options...
desiv Posted November 17, 2015 Share Posted November 17, 2015 Nice! Options!! When I get some time to get some parts, I'll have to give these a try... desiv (Especially since I already drilled the holes for the RCA jacks. My O2 is dying for RCA!! 2 Quote Link to comment Share on other sites More sharing options...
forrestsmith Posted November 18, 2015 Share Posted November 18, 2015 Did the one transistor / AV mod this past weekend on my Odyssey 2. I am really impressed with how it looks and sounds, I thought it the RF looked nice but this really did make an improvement. Demon Attack and Atlantis look great! I used a Transistor that you can buy at your local Radio Shack. Thinking about posting instruction since the information seems spread around the internet and assumes your a electronic expert Forrest Quote Link to comment Share on other sites More sharing options...

I used a Transistor that you can buy at your local Radio Shack. Thinking about posting instruction since the information seems spread around the internet and assumes your a electronic expert Forrest Please do. Pictures of assembled components on actual boards seem to be rare indeed. I can handle simple schematics usually, but seeing close-up images from multiple angles does make a big difference in my mind. As for Radio Shack, it's a shame how they are failing electronics hobbyists in every possible way. They don't make it easy to throw together quick projects these days.

mtshark7 Posted November 20, 2015 Share Posted November 20, 2015 Also besides the video circuit make sure the 5V voltage regulator is in good working order. Mine was giving me crappy video once in a while; even after I installed the video circuit, so I replaced the voltage regulator last week and the picture has been the best it's ever been.

Rob Mitchell Posted November 23, 2015 Author Share Posted November 23, 2015 Go ahead and add input for the Voice if you want that coming out of your TV audio too. Quote Link to comment Share on other sites More sharing options...
SSG Posted November 29, 2015 Share Posted November 29, 2015 I would do something like this to my Odyssey 2, but I am unsure if I want to drill into it. I don't have a problem using RF. When the days of finding cheap CRTs for under $10 are over. I'll be right behind you guys! Quote Link to comment Share on other sites More sharing options...
desiv Posted January 19, 2016 Share Posted January 19, 2016 (edited) Yea man what R. Cade said. I use this one...see attached. Quick questions about the parts from the diagram. R3 is 10 and R4 is 75. Is that 10k and 75k or 10 ohm and 75 ohm??? (Just don't think I've worked with resistors that low, although I haven't done much electronics so that doesn't mean much.. ) Thanx, desiv Edited January 19, 2016 by desiv Quote Link to comment Share on other sites More sharing options...

desiv Posted January 22, 2016 Share Posted January 22, 2016 Parts ordered.. If you don't hear from me again, let's assume I died heroically saving a bus load of orphans rather than failed this project miserably because of my poor soldering skills.... :-) desiv Quote Link to comment Share on other sites More sharing options...
