What We've All Been Waiting For--700 BP boards!!!!!!!!!

[laatsch55]

Oh boyohboyohboy

 

[Northwinds]

Awesome!

 

[BMWR75]

You used these in an amp yet Lee?

 

[laatsch55]

I am WOPL_LESS at the moment and am working to remedy that by getting The Pig up and running. After that(prolly tonight or tomorrow) I'll then tear down Russ' 700B and do it. This is a beta test and the boards won't be released till Joe or I get done with the install to check for any problems.

 

[Northwinds]

I bet your amped up literally!

 

[laatsch55]

Lets say it's getting tedious around here...

 

[Gibsonian]

Very nice to see.

Tedious was replacing all of the TO3 sockets on my 700b.

If this had been available then...I'd have been all over it. It would break my heart to turn around and tear them all out again.

...at least for now.

Some Pictures...

Of progress

Quasi or Complementary? They look real nice!

Only Full Complementary. No quasi option, not enough room.

Those are some nice looking boards Joe. This is such an improvement over the original design - I can't wait to see the test results. I'm sure the listening tests will prove this another winner.

 

[laatsch55]

Nice Joe. I see you can also have a little seep by to the top side. I'm gonna get one yet that doesn't. I know it doesn't affect performance and I don't believe I've done one as nice as that yet , maybe this time.

700F 80W iron setting, flat screwdriver tip on iron 1/8" wide, 63/37 Kester no clean flux, twirl the standoffs with the blade tip of the iron once you get a meniscus formed all the way around, after twirling push with small wooden dowel on top until the solder cools.

 

[laatsch55]

Thanks for the trade secret..

 

[laatsch55]

You were darn sure pinched for room on this project eh Joe?

Shhh! Don't tell anybody Lee

Yeah it is wall to wall Lee and you see I had to add those 2 big jumpers around the thermal cutout opening to assure output plane integrity. I had to use the small form factor 2W MO resistors as there was no room for the big ones from a body diameter perspective.

 

[laatsch55]

OK, LOL... I'm thinkin Nav's hold downs will do the trick to keeping the solder on the bottom side we'll see.
