Choose RG1, RG2
Sets maximum amplification of input mixer (attenuator) - 100k for pure attenuation -
68k (for +47%) or 75k (for +33%) recommended,
Place Resistors as marked in the PCB. If you are in question with the value, please use a multimeter or color chart to check the resistor.
Locate the seven 10nf capacitor as shown below.
Place 10nf capacitor in the spot shown below.
Place 47pf capacitor in the spot shown below.
Its time for IC sockets and ferrite beeds!
Wima Film Caps and Power Sockets up next.
These are the styroflex.
Please Solder with care, we are slightly heat sensitive.
This is how we do it.
Don't worry about the 1k resistors - they are supposed to be missing.
Connect your pin strips to your precision header.
The following photos is for reference how to cut the headers with your snippers.
DO NOT cut off the number of headers shown.
Carefully cut with a blade or your wire snippers.
It's best to line the sharpest part of the snipper directly in the notch.
You need to cut or snip off:
1 piece with 6 connection points,
4 pieces with 4 connection points.
The long piece is extra...
Please mount the brass standoffs to the front PCB Tighten Screw.
Lay the precision stips you cut in the pcb.
Lightly tighten the screws on the other side.
Seperate the two boards
Inspect your work.
Make sure you don't have any shorts or bad solder joints.
Onto making the Panel PCB
Put one small nut on the switch before you mount the panel to keep it the right distance from the panel.
Feel free to throw away the washer.
Mount your pots, jacks, and switch in the right spots.
Don't solder anything yet!
Gently lay the front panel on top of all the parts
Guiding and slightly caressing them into place.
You shouldn't need to use force, just a lot of gentle wiggling.
Hand tighten all the nuts for the jacks and switches.
Add the washers and nuts for the potentiometers.
Make sure all the pins from jacks and pots are coming through the holes they should be in the PCB!
If everything looks occupied correctly, now you can solder it!
Connect the two PCBs together and check your work.
