Well now, isn't that something!! I got distracted yesterday and didn't get a chance to look them up. I was well aware of the Gougeon Brothers global reputation in power boat hulls in the sixties and seventies. An example of heir first windmill design/product is in a park about four blocks from my house. Bay City (now only about 40,000 residents) has just three internationally known figures: the worlds largest sugar broker, one of the top specialty diamond cutters in the world - and the Gougeons.

This is one of those strange "six degrees of separation" stories: The man who owns the auto parts store where I bought my fiberglass stuff is an avid bicycler (also plays trumpet). One of his riding buddies is a Gougeon, and a few months ago we were discussing the bike that dude owns - $23,000. Today a guy in Ohio tells me that the same guy is a great source for fiberglass materials and expertise for my PCB projects - right in my own backyard. That's funny.

I'll check out West next time I cross the river. Maybe I can convince them to develop a new fangle-dangle fiberglass/metal combo amp chassis design.

OOPS! Cant forget Madonna - Born here and lived with her grandmother who's grave she visits often. Ran into her at Jack's Fruit Market about fifteen years ago.

Nope, can't forget Madonna. She graduated from Rochester Adams High School in Rochester, Michigan in 1976. I graduated from there in 1975. As far as cheerleaders go, let's just say there were several others that were, ahem, better looking...

This smoothing step is optional. A blob of Bondo, some paste hardener and a full mixture with a plastic tool.

A thin layer that mostly just fills in the fabric weave.

Some sanding and flat black paint (might use red someday) and the board is ready.

This is where the PS layout changed so I used the big piece shown earlier.

Layout/spacing for parts.

Drew out the plates and connections and transferred that to the 0.025 copper.

This time I used both scissors and a scrolling band saw blade for the cuts.


Attached double sided tape and stacked everything for uniform hole positions when drilled on a drill press. Still messed up a little.

Everything seems to fit !!

Caps were soldered in first. Hand drill and file still needed for a few adjustments

Alu scrap to keep resistors up off the board.

Was going to insulate and wrap 0V leg over the rectifier leads but placed it on the top of the board instead.

That's it!!! Both units make +/- 25.4 VDC on today’s tests.

Now don't be telling me that it's too much fuss and mess and takes too long. I have a bunch of friends my age who don't realize that if you don't hit a silly white ball with a stick – you wouldn't have to go chase it. They spend hours doing that repeatedly and never get the point.

Some spend endless hours polishing their vintage silver 1968 Shelby Mustang - and never drive it.

I think this is a more productive use of my time.

There are some bleeder resistors to add before the first set of caps, but I only had two and I don't want to pay $7 shipping for the other pair. On next online order.

Thanks.

Yea, when I was in high school "The Market" was always set up for hockey or speed skating. Now days they only use it for flea markets and Christmas tree sales. My HS choral director had a son who did speed skating in the Olympics - and Terry McDermott got the gold in 1964. We'll put him on the BC favs list right after Madonna

Terry McDermott, I remember him. As a kid I did a little local speedskating. Then we had a big meet (maybe 1959) and Terry was in it. Then told me that the next season I would race in Terry's class. I didn't race that next season. 15 years later we got a new rink and I slowly got back into racing.
