Subject:Voce V5 Percussion Upgrade in 17 steps

Hi -

with the help of this forum (thanks to Dave, Andi and especially
Ramon!) I was able to perform the percussion upgrade to my Voce V5.

If you have soldered before, it is no rocket sience, you should be
able to do that w/in 20 minutes or so.

According to Dave R35 must be lowered to 22kOhms (original:
68kOhms) - as the board is quite packed and w/ a special design (to
combined boards) I recommend to solder in a 33kOhm resistor in
parralel to R35 - which then results in a resistor of 22.217Ohms
(1/Rsum=1/R1 + 1/R2 ... remembering the electronics theory class ;-
) )

So - how to do it? you find some pictures in a new album - here:

1. buy a 33kOhm resistor (small series) - (cost: 11c - ok, an
expensive shop....)
2. put the V5 onto a clean table
3. pull all the drawbars out to the max
4. unscrew the small black philips screw at the back and on both
sides
5. Pull off the knobs
6. unscrew the line out nut and washer
7. lift off the cover - you can see the upper board now (see

b=1 and

b=2)
8. locate the four silverish philips screws. Screw them out.
9. lift out the board and turn it round. (see
http://launch.ph.groups.yahoo.com/group/CloneWheel/photos/view/a85e?
b=2) Watch for the white washers between the board!!! They are
needed for proper alignment!
10. Locate R35 - well marked on the board, you will find it at the
fromt of the 7th and 8th drawbar
11. Solder the 33kOhms resistor on top of R35 (see
http://launch.ph.groups.yahoo.com/group/CloneWheel/photos/view/a85e?
b=4)
12. The reassembly starts here.... after some fiddling I worked out,
that the easiest way to do it is by putting the drwabars and faders
to their max positions. Check well for aligment! Don't forget the
white washers between the boards! Then turn the board and put it
back in position. Shake the whole unit a bit until the board comes
not just close but fits with the case - and try every single
drawbar.
13. repeat step 12 until all drawbars work well
14. screw in the 4 silverish philips screws
15. Put the orange cover back on top, put the knobs back onto their
pots, screw the side and back screws in
16. Enjoy the upgrade!!!! It is well worth it!
17. Repeat 16 as often as possible!

ciao,
Stefan
