Archive of the former Yahoo!Groups mailing list: Homebrew PCBs

Hi all, I am building a tube guitar amp PCB. It requires heavy
copper on thick boards. I would like to use 1/8" boards, but cannot
find any locally. Anyways, here are my plans:

Toner transfer method using Phoenix TTS paper (all I can get here in
Canada). Then I plan to etch using MG Chemicals Sodium Persulphate
and hand agitation.

Is this reasonable for this thick of copper, or should I try a
different method. Any hints, tips, or related sites would be appreciated!

thanks
Don
