[orange]

At least you aren't a Teenage Mutant Ninja Technician...

How do you know. Just might have my Magic Soldering Iron right herew.

Ready for a board.....

Ready for a board.....

Nice neat job Lee...Russ will be pleased.

 

[laatsch55]

That's what we are striving for Joe...

That's what we are striving for Joe...

I find that they always seem to sound much better when done as neatly as this...the electrons behave in a much more disciplined manner

 

[laatsch55]

Done with the board, now a row of outputs and power up for the first time................

 

[laatsch55]

One must first break them to lead Joe, then break them to lead gracefully..........

You can hardly tell that is a PL400 anymore, at least from the inside

 

[laatsch55]

Well.IT ISN"T!!!! It's a White Oaked Phase Linear----A WOPL----I love being able to use 6 X 32 Allen Heads!!



Don't have to have the TO-3 lerads plumb square anf flush with the world, OR file the lead ends so they'll go without fuss..... The list goes on.....

Rail fuses were AGX 8', mains in was an AGC 8. Replaced with AGX 5's in the rails, AGX 10 for mains in. Here we go. Got the DBT in line with the variac, the AP{ is warming up and the Fluke is on the bias test points,,,

Offset---Left-.021, Right-.021 Bias ,pots midway, Left--.327, Right->320. AND THE F(*&^%$ DCP DON"T WORK!!!!!!!!!!

Maybe you should put the relay in?

 

[laatsch55]

It was in Dennis. I thnk we have a non-workinh UPC 1237.

That's a bummer, I can tell you were ready Lee

 

[laatsch55]

Everything White Oak went smoothly....

 

[laatsch55]

Frequency Response---UNWEIGHTED--

 

[laatsch55]

Crosstalk and Signal to Noise Ratio

 

[laatsch55]

BTW-----That SNR is world class at unweighted, the weighted at 114 is also world class....

 

[laatsch55]

Noise Floor-----Outstanding!!
