MPF-102 on Millenium Bypass

gamberone · 29th June 2009, 11:30 PM

Hi.
I want to realize a millenium bypass circuit for guitar effect

http://www.geofex.com/Article_Folder...ium/millen.htm

Can I utilize the BF245 instead of MPF-102?

Many Thanks!

PS: The BF245 can repleace the BS-170?

Hi gamberone the BF245 should work fine as it has a similar Vgs to the BS170, and you can always test it on a breadboard first of course

I have built this circuit myself and can probably give you some troubleshooting pointers if you get stuck.

Happy building

You can replace MPF102 for a BF245, but you'll have to twist it 180º. The BS170 is a MOSFET, not a JFET, so BS170 works for Millenium 2!
