Hello everyone. I recently got an Odyssey 300 from a friend that had it working. Unfortunately it doens't work anymore. I was able to narrow the malfunction on one of its transistors. I suppose it's the one that feeds power to the machine.
As you see in the picture, i have removed it because it was broken. He probably used wrong voltage. The transistor reads 224-1 701 EBC.
I went to an electronics store but the couldnt find a replacement as they said that the code is from the manufacturer. I suppose you have more knowledge on the subject.
Thank you for any tip.

what is your opinion of the odyssey systems, Have thought about maybe adding one to my collection one day.

[Ethaniel]

well... it's not Odyssey 1 but it sure is a classic piece. It's also cheap to get

That's what I was thinking, thanks.

bump, bump

I know people with the schematics for 100, 200 and 4000 but noone with a 300 and its alot different than the others. The Wonderwizard has the same board if you could find out anything about that

Oh and for reference Odyssey is amazing. the dedicated pongs are okay but not the same

I'd try a general purpose PNP transistor. Was it a TO-92 package? If so EBC usually means PNP and CBE would mean NPN.

i have noooo idea what you're talking about...
im not THAT good in electronics.

Show me a picture of the part. From the font used to print the number I can tell you the mfg. and then cross-reference it to a replacement.

I just purchase a book with schematics for this system the other day, with the expectation of helping you out. Ill try to scan it for you when i get it

I don't think I have the part anymore but thanks anyway

I'm looking forward to it! Thanks

[njb12287]

I sent you the best scan I could get

[Ethaniel]

the scan is not very clear but i think i spotted the part i need! it's the Volt regulator 224NI if i read that correct.
is this the name i should ask for in a store?
