[sdiy] beginner SDIY... larger Pot values & carbon VS. Metal film resistors

[Todd Sines]

Thanks for the tips guys.

How is it that attempting the avoid the inevitable always ends up  
getting me in the end? ;)

Guess I have to wait (and I ran out of plenty of stuff anyhow so it's  
back to making my 808 front panel)

Enjoy your weekend.
