im going to do a pnp rangemaster using the ggg schem
http://www.generalguitargadgets.com/dia ... _sc_pp.gif
i did a layout for reference if anyone wants to use it but theres already hundreds of layouts for this thing~


mojical mouser parts that i hope i ordered correctly, a few have multiple options
Mouser #: 594-2222-021-36479 Miniature Axial Electrolytic Capacitors 47uF 25volts 20%
Mouser #: 539-150103K630BB DC Film Capacitors 630V .01uF 10%
Mouser #: 539-150103J630BB DC Film Capacitors 630V .01uF 5%
Mouser #: 23PS250 Polystyrene Film Capacitors STYRENE 50V .005uF
Mouser #: 30BJ250-470K 1/4W 5% Carbon Composition Resistors 1/4W YW PR YW GD
Mouser #: 66-RC07GF474J Carbon Composition Resistors 470K OHM 5%
Mouser #: 791-RC1/4-474JB 1/4W Carbon Composition Resistors 470Kohms 5%
Mouser #: 66-RC07GF683J Carbon Composition Resistors 68K OHM 5%
Mouser #: 791-RC1/4-683JB 1/4W Carbon Composition Resistors 68Kohms 5%
Mouser #: 66-RC07GF3R9J Carbon Composition Resistors 3.9 OHM 5%

_________________

i have a question or two about the circuit... first a correction to the above mouser order, the 3.9 resistors arent the correct parts, they should be 3.9k so dont order those ones...

is the rangemaster crackle ok or do i have a bad pot or what?
on a black glass oc-44, what does the red dot imply? i placed the transistor so the red dot connects to b1, that orientation was louder.
and
does anyone know the 3 way toggle switch mod?

thanks! viq~

_________________

Crackle while adjusting the pot is normal. The DC voltage on the pot is the cause.

The red dot indicates the collector.

Not sure exactly what you mean by the 3-way toggle mod. Is it to change the value of the input coupling cap? This is easily done using a DPDT ON/OFF/ON switch. Connect the poles of the switch to the leads of C1. Then connect the caps you want to connect in parallel with C1 across the throws of the switch. I usually add a second .005uf cap and a .01uf cap to the throws. The OFF position uses the .005uf cap, flip the switch to make the input cap .01uf. Flip it the other way for a .015uf input cap.

thanks! the toggle switch is used on the beano boost, heres the description of what it does to the sound
