And here is the Tycobrahe Octavia which confirms my trace and theory:

even the original Roger Mayer Octavio schemo traced by the Tyco people can be found here.

read more about the history here:
Octavia History - Truth revealed ?

Octavia Evolution courtesy of Roger Mayer
and here:
Roger Mayer Octavia Octavio
and look at the:
Tycobrahe Octavia schematic
and the
Roger Mayer Octavia schematic

This is the wrong Helios schematic where all came from:

The schematic on my website has been upated today.

Had a chicago iron version in today. Identical to all the ruling schematics. Great unit.

One point; the DC jack adapter on the back was printed wrong. You would reverse the polarity if you'd follow that.

For only $1999.99 it can be yours.

I've got a Chicago Iron Octavian Plus prototype (confirmed as #6/25 by Chicago Iron and signed inside) that I'm not sure what to do with...I've built a billion fuzzes already, so it doesn't get played.

You guys seem to have a handle on the schemo (as it's all over the internet), so no need to trace, I suppose:

You kidding?

Show the trace side, pretty please

Any marking on the transformer?

I'll take a look tonight. It's for sale, but probably will still be with me for a few days at least...

Crap. Sorry Sinner, I was going to take better pictures this weekend, but a guy came and bought it from me today as soon as I got home from work. Wasn't even time to get the back off!

I've got a funky fuzz on loan from a friend that I could take shots of though...

No worries, I'm sure we will have this opportunity to look inside in future

Those are from the auction I've linked for record. It looks like ebay did some magic and downloading picts is not that easy. I had to play with webcode

Bernardduur · Post by **Bernardduur** » 19 Dec 2011, 11:52

I had one of those newer versions in (chicagoiron???) which was blown because the DC jack was wired different from what was written on the unit (it was wired for a normal DC adapter standard in pedals (+ on the outside, - on the inside of the barrel), the writing was the other way around)

The unit was a 1:1 copy of the older Tycobrahe schematic!

interested on transistors and transformer marking

My man! Thanks for this

Yo!

I'm wondering why no one have done this earlier

Anyway, it's not 100% replica layout, but should be pretty close to original.
This one should fit 1590P1 enclosure and is sized for 42TM022 transformer.
In orginal octavias transformers are little bigger.
I will post later tighter layout for 125B enclosure.
