My DIY IIc+ preamp (build plans for PCB available)

[bancika]

few factors:
* there's a local company that can make any tranny I want
* they cost a half or even third of what brand transformers cost (this one is less than 20$)
* I can't buy brand transformers here, so I have to order them from abroad which makes them even more expensive.
* there's a good chance I couldn't fit an EI tranny inside this chassis

You can use any tranny you can get, even two small transformers back to back (230:12V or 120:12V for USA wired to 230:6V wired reverse should give about the same voltage as my todoidal).

Cheers

update. I finally finished the preamp and it's awesome. Still need to finish the figured maple shell but it doesn't stop me from using it

More info, schematic and clips here http://diy-fever.com/amps/mesa-mark-iic-pcb/
There's only one clip so far but I plan to add more soon.
