I was wondering if someone could give me the value of the frame mounted transistor on a K7500 that receives the three wire plug. I looked at mine and a leg is broken off. I looked through the manual and couldn't find exactly what I am looking for. I am wanting to put in an order with Bob and would like to include this.

Edit: I think it is: BDX53. Can anyone verify this for me?

Thanks.

Great thanks. Now, I also noticed that L701 is a coil type of thing and it is broken but still attached. Anyone know where to get a replacement for L701 on the K7500?
 
Bumping this; I am missing this entire setup, and I have the 3 wire red molex connector connected to nothing as a result.
So my question is, what do I need? And a pic would be superb!
I have capped it and replaced the cracked fly and it looks excellent, except it is too skinny and I can't adjust it, obviously. It's in a Cali Speed.
Thanx
 
Buy the transistor, connect the connector, mount it to the frame (insulated I think? Sorry, I'm not home now.)

Today I ordered the transistor X 2 and a few 300uf 63V caps from Mouser. And I'll be sure to insulate it, thanx. All the other K7500s I have worked on did not have separate wires with the red molex deal, this one is new to me. The pic looks superb now, just has about 1.5" black bars on each side. Hopefully the incoming parts take care of the width issue. Cheers!
 
No insulation.. But last post is correct, doesn't hurt to insulate..

Have 2 right here, both no insulation.. Just need flybacks :(
 
Ok, installed, insulated and now the pic 2" too wide, and the width pot still does nothing. Have tried two different remote boards and 2 different remote cables, no dice with either one as far as width. Guess I pull it and remove the mica.. GRR...

EDIT: Well, that made no difference; dammit.

I have continuity from the remote pins on the board to the remote width pot, so the pot should be getting juice.

Any other suggestions as to why the width pot is not doing anything? I am assuming the red 3-pin connector directly on the legs of the transistor? And it is a BDX53B that I mounted on a brass bracket.

Is this correct?

I think you've got the transistor plug on backwards.

BTW, you can turn it on without it plugged in. It'll come up keystoned (pincushioned).

You may have destroyed that transistor though.

Mine may not have the same transistor, but my white wire goes on the left leg, you appear to have it on the right leg.

Yea, when I got this game, there was no transistor or mount anywhere and the pic was good (after capping/fly), just too skinny, leaving about an 1 1/4" back bars on each side.
And when I first installed this today, I had the connector on the other way initially, but the image was too wide, and width pot did nothing. So i flipped it around and garnered the exact same result. Too wide, non-responsive VR900. And I have flipped it back and forth a few times using different remote boards and cables, and the result has been the same.
I am stuck.
