I found the thread, "Help!!! with G9 Power Transformers", and used straycat's post to decipher the code. Yeah!! The G9 lights up. Wait!
She's fading captain.
So, more reading and it would seem that I am overheating my 7812 chasis mounted regulator (but I'm not sure). I noticed some pretty big heatsinks in finished G9 pics.
Question 1: How big, or how small, can the chasis mounted heatsink be?
I'm using an aluminum anodized cheapy from the Shack. It's 1 inch wide
by 1.18 inches long and .05 thick. Is that sufficent?
Question 2: Does electrically insulating the regulator from the heatsink
require two washers? One between the heatsink and regulator and one
between the nut and regulator?
And one more:
Question 3: At one point I had hooked the trannies up wrong and the
G9 powered up. If I blew components, does anyone know the usual suspects? Like, "Dude. I'd be suprised if you didn't fry all those diodes."
Thanks for taking the time to read this. If anyone could help with any of
these questions I'd be mighty tickled.
take care,
cletus
