Need a horizontal output
I have a Hitachi YV model #50EX10B. I called Tritronics for the
horizontal output transistor, and they said it is no longer being produced, that they don't carry it anymore. I'm sure I don't have to trash this set because I can't find a HOT. The part # is 2SC4529-04. It's component Q777 on the schematic. Anyone have an idea where I could find this part? Thanks all. |

The schematic shows a 2SC4589-04 part #2315273.
NLA as a Hitachi part but call Universal Semiconductor 1-800-222-2321 , they will have it.

Thats the part. I typed in the wrong part #. Anyway I will try these suppliers. I've never heard of either, which is good for me since I now have more resources. By the way, the reason I need the HOT is because the original is shorted. I crossed a HOT that I thought was close enough, only to have it also short out. The supply fuse in the secondary is also blown. I've checked associated components at the collector side of the HOT all the way to the flyback and beyond, but don't see a problem. Maybe just time for the HOT to bite the dust? This set tries to power up but shuts right back down in a second or 2. Have to unplug, and plug back in to go through the same sequence, otherwise dead. I hope that a bad HOT/open fuse will cause this symptom. Any feedback on this same old subject would be great. I am a beginner by the way. Thankyou. |
