"S" G9 Pics & Xformer guide *Not for 56k'ers*
« on: May 31, 2006, 10:13:23 PM »
Here's my finished G9 which has been done for a few months, but I haven't had a camera to capture its beauty with until now.  So, naturally, the G9 (or as I called it the SG9) was the first thing I shot with my new camera!

And finally, a toroid wiring guide I drew up for this project:

Being a 56ker, of course I had to look,  :twisted: and wasn't too bad (load time). Way faster than most PDF's.   The problem is,  my monitor is to small to see the pics!  (just kiddin'!)  Nice work, man.  :thumb:  :sam:

Very very nice!  :grin:  You did a gooood job!

One question: I see two additional caps on B+ (245V) with 10µF. Do you have some hum left or what was the reason for this? Thanks!

very nice :thumb: any oscilation problem on ch. 2? If I'm right there is wire going directly from ins. jack to Cxx?

Yes, an impressive job ! And a very nice rack :cool:
A good design also for the front panel, with some (!) inspiration for my G9...
Is there a copyright on it ?  :green:





Thanks Skylar ! And of course Jakob and it's amazing G9.

I the colour!  :thumb:

Iam a bit afraid with using this (facetted :wink: ) pilot light because one side of it isn't isolated with the chassis? (gnd loop) I used leds instead of the light bulb.

Thanks for the kudos, guys.  I couldn't have done this project if it weren't for Jakob (of course) and many other forum users who built the G9 and posted their problems & solutions.  

So, everyone give yourself a big pat on the back!


Wolferl,
I assume you're talking about the big, blue Spragues.  I didn't actually use extra caps there--just really big ones.  No reason really, it just felt right.

guavatone,
I did a mock up of the entire frontpanel in photoshop [more info in this thread: http://www.groupdiy.com/index.php?topic=14719 ] by measuring the physical dimensions of all the parts (knobs, instrument jacks, jewel, toggle switch) and adding graphics around them. I then transferred those graphics into Illustrator and gave the Illustrator vector file & pre-drilled panel to my local screenprinter.  The font used is Avant Garde ITC.  

suprughetto,
I had pretty extreme oscillation problems on both channels.  I switched to shieled wire, and that solved the osc problems on CH1 entirely.  CH2 still had osc in the last 2 gain stages, so I cut traces and ran shielded wire directly from the PCB to the instrument jack.  Voilà!  No oscillation whatsoever--this G9 is totally CLEAN!

Campistron,
Very Nice!  I dig the graphics *wink*.  

If anyone would like the Illustrator graphics to use on your own projects, let me know--they're free for the taking

Skylar: I modified your document to show the wire colors for a few of the more popular transformers used in the US. Hopefully you don't mind. I think it could come in handy for others like myself who have limited knowledge about toroids and come across this thread. I found the best way to look at the diagrams is to look at each transformer independently and compare it to the guide linked in a post above. IOW, even though transformer #2 is fed backwards, if it doesn't make sense, think of it as a typical 220v hookup flowing forwards; then reverse the flow.

Since I altered these in Photoshop, I had to leave out a few of the cool features you used.
