WOPL 400 1st time build

[plex]

Thanks for the advice. I also just completed all of the required tests in the backplane bringup PDF up until the second row, then installed the second row, made sure all of them were installed properly, did the DBT as instructed, but the bulb did not dim. Could it be bad transistors or is it something else?

good to hear from you...i missed you!!!

Thanks brother. I been lurking time to time but mostly taking care of Mama.

use the dmv and check transistors first, then....
change the sil pad...avoid overtightening...check the pins from the inside...
got that tee shirt too....anyone here will tell you i have a closet full of tshirts...
persistance will win....
there is so much knowledge here....the guys will not let you fail...
they sure as shootin....took care of me...

your dcp relay will tell you if you have dc....
it will not engage...watch the blue diode or listen for the engage click....

You can also use your meter to check for a grounded output case. Recommend downloading the output data sheets and check outputs in a orderly manner noting results on a piece of paper. I use a sharpie to number them on the silpads side.
And, you are following the Full Complementary PDF Graphic that Joe provides for installing the outputs? The backplanes dictate full complementary output topology.

Thank you. Yes, I have been following the full-comp instructions. I took out the transistors that I put in that row before and put in another set of four, and the DBT went fine.

 

[gene french]

go!!!!

 

[George S.]

Sounds like you have a bad one in that row you replaced.

 

[WOPL Sniffer]

I checked my wiring and checked the AC and DC inputs of the DCP board, and there is little to no power to them.

The PL400 is complete. Thank you all for your support and help. The White Oak instructions are very easy to follow, but a takeaway from this experience is learning that you need to read and reread the instructions and not jump the gun.

I was having trouble with the rows due to the overtightening, thanks for the advice. It was such a simple thing but easy to overlook.

Congratulations on you and your son's build. Quite a achievement. Hope he learned a lot!

Thank you. Yeah it was a great learning lesson and we had fun doing it. Also made new friends here. Thank you all.

 

[gene french]

congratulations !!!!!!

 

[gene french]

they sound a lot better when you personally build it...lol

6-7 inch-pounds is not very much torque, but it will do.

Yeah lesson learned.
