Amplifier Discussion / 25 ohm pot replacement
October 25, 2006, 08:06:14 PM
Hi!
I'm trying to build the little gem amp but i can't get any 25 ohm pot anywhere in town (on one place they could order it for me but it would cost me 40 dollars :S )
Does anybody know If I could use any other pot or something similar?

Thanks a lot!

Hi everyone
I finished my first project and I'm on my way to a second one
I'm trying to build this metal pedal :

but got some doubts about it
first, it says "hfe-170" and "hfe-225" next to the transistors. what should I do to obtain such gain?

Preamps and Effects / Apollo Booster help!
October 08, 2006, 12:35:18 PM
Hi
I'm trying to build the apollo treble/bass booster.
I've already put all the part together as the schematics from rg green suggest, but i can't get it to work

Has anyone ever tried to build this?
is there anything I should add to get it working?

Sorry if my questions sound too stupid, it's my first electronic project ever.

Thank you very much
