AH! Good call Ed, thanks for the info, glad you covered the bases.

Yes - on planes you NORMALLY add thermals. The thermals on this board
were deleted on purpose.

After calculating current draw thru the narrowed traces of the thermals -
I would have exceeded the maximum allowed by ANSI/IPC specifications so I
ditched the thermals. In the US - I gotta consider meeting safety rulings
else risk getting sued. E8 is the only place where the installer runs
into any problems and a lot of heat is required to attach wires (which
doesn't hurt to use a lot of heat). This is why I put a screw terminal
right next to E8. But I don't really mention this in the installation
instructions... gotta revise that.

There should have been thermals added to all holes in the plane; this
lessens heat dissipation through the plane and solves the soldering
issue. Not questioning the quality of the product of course, but a good
board designer should utilize this. I am assuming the layout was done by
a second party, and unless instructed to (or not having the knowledge
themselves) it was a basic requirement that they overlooked.

I installed one of Ed's rectifier boards as a repair for a customer of
mine. I agree, a fine piece of work. I too had the same problem
soldering the ground wires on all that copper but finally got it on
there. Very well laid out, plenty of room for soldering the
transformer wires, and everything on top is clearly labeled. Very
nice!

I have two of Tom Callahan's boards in my two Bally machines. The've
been in there for several years and I've had no problems w/ them.
Comparing Tom's to Ed's I'd say Ed's is better built, plus it's cheaper
too. I'll use Ed's in the future. I've delt with GPE for many years
now and Ed always comes through for me.

My only complaint? Label the transformer holes on the bottom of the
board too.
