Whites Surf PI schematic

i dont no about that
i must make new coil first to make test its work or not

[seadoggy]

now i test with multimeter my voltage on pcb is +06.5 -06.5

how much in coil??

[paku]

now i test with multimeter my voltage on pcb is +06.5 -06.5

[seadoggy]

i dont test wtih multimeter
i just tune it with scope i put the test point on the coil connect to pcb and i try tune the 5k pot now the sound has gone

my all pots working fine,just sound is low,and no beeeping whit out coil,when hook up coil beep just once

[paku]

i dont think its have secret heheh,how much u have volt where you hook up speaker and also in coil?i have 8,++ volt in place where connect speaker in a coil 0,56 volts

i dont test wtih multimeter
i just tune it with scope i put the test point on the coil connect to pcb and i try tune the 5k pot now the sound has gone

joop u ar right

i use the oscilloscope test point at the coil and i try tune the pot now the sound is gone
so i think the problem is coil right i use 6 diameter 20round wire
now no sound but i must make the new coil

[paku]

i have but i dont know how to test point on that pcb

[joop]

Paku, you told me you have an oscilloscope, why don you post some oscilloscope pictures of PCB measurements?

here is some pic,pls help guys

[seadoggy]

Does the sound change when you turn any of the pots?
