Voxy Brown - CB Galileo (Video)

[TreeSlayer]

Could someone share their FET voltages on the CB30 side?

I would, but for some reason, I can't find my build docs...

Cool. My CB30 side is just sounded really farty. And I'm not using this layout, it's one of my own.

Sorry don't understand the CB30 bit, I have built the voxy Brown and it works.

Your last post has just clarified why I don't understand...different layout

[irmcdermott]

The Galileo is a Catalinbread CB30 and Naga Viper in one. I just need voltages for the transistors.

So volts for the  Q1- Q5 which are the fets  2N5457  ??

I can take them and get back to you, if thats any good.

Volts taken wrt Ground

Q1  D 9.15    S 5.16   G 4.35

Q2  D 5.16    S 0.53   G 0V

Q3  D 4.99    S 0.694  G 0V

Q4  D 9.15     S 5.0v    G 4.37

Q5  D 9.16     S 4.93    G 4.22

Wow, pros work!
what about the lazer etching. how is actually done? where did u find it?
I can get only acids around here
cheers

Thanks. i'll check mine when i can get back to my bench. Appreciate it.

Thanks! I got a local wood shop with a laser to do the cutting. THe enclosure is a pedal parts plus powdercoat.

Someone want to do a demo of this thing? The iPhone video of my crap playing really makes me cringe.

[okgb]

just got all the parts , can someone confirm which way the pc mount pots are , over the board or off of it?
tia , I 'll look harder as well.

[TreeSlayer]

this is how I did mine...

[okgb]

If that works must right thanks
Also anyone know how far in value I can sub for the 2.2 uf caps ?
I have 4.7 handy but's more than double, tia

[TreeSlayer]

that pic was an old build. you've inspired me to build another one, but this time i'm putting some silver mica mojo in this one, and experiment with some other caps and transistors. here's where I am so far.

[okgb]

 Yeah I was wondering how it affect my build with some " lessor " caps I've used

Anybody ? How critical are the 2.2 uf caps ? one is on the output
can I sub without anything strange happening ?

[jubal81]

If you don't have a 2.2uF, I'd recommend a 1uF rather than a 4.7, but you'll still get sound with either one.
