Sorry !! today I'm asleep.....

MIROSOL:
Two caps 22nf in vero?
Schematic: 22nF and 22uF
What is the correct value?

The JBF-3 Clone also includes a Millenium bypass circuit to control the LED using a DPDT switch!

Hi Walter: Another equivalent MOSFET for Q1 (ZVP3306A), please?
Thanks

In the original unit: what transistor is used?

Interesting discussion here! Hey, where does one find those big yellow AD .01 uF film capacitors, chicklet type? I have done searches for those but nada... oh and would a vishay Roederstein film cap work as well? The caps are PHILIPS, for sale here: http://www.ebay.es/itm/1-PC-Philips-341-Capacitor...

I've tried connecting 2M resistor like in Rugeb's schematic and tried BS170 and MPSA18 like he suggested. To me, the circuit became much more clean and it doesn't distort much at the maxed gain settings. I guess this can be an improvement if you are looking for super clean boost. But I'm looking fo...

The OXBLOOD DISTORTION: "basically" the same circuit (more or less...)
.

I've tried with BS170 (MOSFET) has worked well, sounds good too: RECOMMENDED!
·

Schematic with TONE CONTROL: sounds good! a very important improved.

I think the circuit need a high gain transistor (MPSA18: Hfe=900)

Very important the pots value!!

IMPROVEMENT: resistor R2 connected over collector-base and Q1=MPSA18: sounds very good!

Schematic with mods: Pulldown resistor (anti-pop) and clipping diodes (for transistor amps):

Originally, what transistor they use: 2N50088 or Darlington?

Here you go! https://i1199.photobucket.com/albums/aa ... ences1.jpg

The original transistors: BC183 and BC183C :

Cool!
