MPF-102 on Millenium Bypass

[gamberone]

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

http://www.geofex.com/Article_Folders/Millenium/millen.htm

Can I utilize the BF245 instead of MPF-102?

Many Thanks!

PS: The BF245 can repleace the BS-170?

No one can help me?

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

Can you describe me the problem you've had?

Bye.

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!
