Clean Blade Boost v1.0

If you want to make it a 100% copy of the original then you’ll need to replace VR2 and VR3 with 4k7
resistors. Connect these resistors between pin 2 and 3 of the VR’s. The Pins are clearly marked on the
PCB. Else it is now time to solder VR2 and VR3. Try to pre-set them at 4k7 by measuring the
resistance between pin 2 and 3. (PS the schematic on page 7 shows 10k pots but in practice 25k is
much better for biasing different transistor types)
Finish by soldering the electrolyte capacitors. Place the transistors and you are almost ready to rock.
If you are going to use a 250k alpha pot with integrated DPDT than you will need to drill the hole
in
the side
of the enclosure and not the top of the enclosure as the DPDT pots are too tall for a 1590B
or BB enclosure!
Besides the components mentioned in the table on the first page, you will need:
2 input jacks
. 2 mono jacks if you are not going to use a battery and only the 9V adapter. 1
mono (for output) and 1 stereo jack (for input) if you will be using both a 9V battery and the
9V adapter.
3PDT footswitch
(9 pins).
2,1mm DC jack
(isolated).
9v battery clip
(optional).
22 gage stranded hook-up wire.
Hammond 1590B
case (or similar) in your favourite colour.
