phase linear 400

Other advice Gene, sell that PL200, the worst amp made by PL. The PL200 S2 was a solid performer but not the S1. The S1 looks to have been designed by their summer interns...

Gene, probably hasn't been mentioned, but many of the guys make a custom buss bar for between the caps. I find the original is adequate, so I use it. However, I drill extra holes for the extra ground wires. Two holes on either side of the slot, sized to each hold two 16 AWG wires. Then I steel wool it to make it shine, then clean with alcohol. A little bit of flux and it then solders nicely. Plan ahead and drill before doing any soldering. Also note how the wire enters the slot from behind, then is bent over the top. Takes a lot of planning on how to fit all those ground wires.
Also, the S1 transformer wires are enamel coated solid core magnet wire. PL probably dipped the ends into a solder pot to burn off the enamel and tin the wire ends. If you change the length of them, scrape the enamel off with a Xacto blade or something similar before tinning them. It might take a couple scrapings and tinnings to get them correctly tinned BEFORE you solder them in place. A little flux also helps here, not much, just a little.

resistors in....



going to diodes....

wanted to get used to soldering the double sided board before i did the diodes...to get the feel of how much heat needed to flow to the top nicely...i think its ok....

and
your missing some resistors

this version of the driver board....is built for full or quasi compliment....and some parts get installed under one config and vice versa....
this kit is labeled extremely well....and for me...does not assume too much nor assume too little...
assume is a word to get you in trouble....when and a** comes before u and me...

Gene
I see some diodes backwards,, check w sheet to find them

 

[George S.]

D12A, might be others.

 

[George S.]

Gene, just take a deep breath and relax. It'll be alright. Use some desolder braid, flip them around, they'll be fine and have no issues. Just take your time and don't rush. Keep posting photos.
