you should have about 57v ac at tha ac connectors of bridge rectifier
14a , yea left is being a butt head. no fuses blowing (yet) . dbtester ? light bulb? dimmed after start i payed all my attention to right side durning this rebuild , oh my , ill have as much in this board as a new W.O. board with terminals heck with those wires (fine for assem & go) not for the novice trouble shooter as i am.
all i need is two 410's and i could throw all the xpl909s and 410s back in , it was my fault they went out anyhow dam meter lead...
be careful how much you torque dow output screws ...too much will give problems...dont over torque

Hey! I disappear for a year and come back and Gene is the one giving advice now! That's awesome. I have still not started my WOPL 700... Too many other projects in queue and I've been too satisfied with the 400 to get the upgrade itch yet.
I saw one of Perry's 700s2 builds on eBay and it made me want to check in here... Great forum for sure.

the ps cap upgrade will make a noticable difference in the bass...
made a world of difference in the haflers too!!!
i have a 200 s1 that i recapped...then one day one meter pegged.....was advised here that is best to let it go peacefully to that studio in the sky.....
i might one day fix it... just to see if i can...
enjoy....

i used white oaks led boards that i had bought previously....removed the leds and wired in the led filaments...much brighter and adjustable...
i have one more set but without white oak board...
might give that a shot...may take a bit of experimenting to get brightness equal...
i have spares...not high on my list...
