I designed a simple SRPP PCB for my own project. A special thanks to my friend, Mr. ATP who helped to process the PCB fabrication.

Well, later these days, I just feel more comfortable with PCB rather than point-to-point wiring. It’s nothing special, just an ordinary SRPP design.

Well, this is a surprise news for me (at first). A “Made in America” PCB? Seriously?

Few months ago, my friend introduced me to TubeCAD (and finally led me to John Broskie). Actually, I knew his TubeCAD Journal and even his famous TubeCAD software 1-2 years ago (or more). But at that time, I didn’t have any interest on such technical things (like Broskie’s journals). Until finally, I heard his Aikido pre-amplifier and quite stunned how come a simple pre-amplifier (with cheap components) could lead into magical sound! Then I changed my mind and started to read some of Mr. Broskie’s journal.

My interest in some of his articles led me into a personal communications via e-mail (well, I do enjoy the modern technology, I wonder if I should send him an ordinary air mail to ask about his article – it will take years before I can get myself answered! With e-mail, within a night – due to different time zone, almost all of my questions could get the answers).

Finally, I decided to order his Aikido 9pin Mono PCB. John sent the package via express mail. It arrived around 2 days but due to custom issue, I accepted in around 5-6 days. Still quite a fast delivery

Here is the PCB. Dual sides, plated-through 2 oz copper traces. Don’t forget that both sides are silk-screened.
