Pdk,Mr'valdeni

Hi All
this is a pdk for Mr'valdeni designs,i see a pcb and schematic to youtube chanel Mr,valdeni and made this a project,
i changed antena to loop 8 DESIGN, L1 100 turn 8cm diameter wire 0.30 and L2 147 turn 8cm diameter wire 0.30.
and made ferrite antena by orginla deagin,
field test:
By ferrite antena spark 1.5 v battery by 25cm wire 1mm sense at 100cm our 120 cm
and test by loop 8 design
Sense 1.5 v batery spark at this 160 our 170 cm and strongest at ferrite to the test
and sense monitor flatron 720 at the 200cm, can a this pdk senseba gold and silver old?
i put a transisor bc337 ,and bc556b ,i cant see for transistor bc556 c ,how beter this transistor for project this B our C?
And a 1 test wich a 220 v key home lamp 20 our 30 time click the key lamp i sense. 20 meter for 220 v spark this my pdk,
i one night test pdk by 220 v spark at 10 meter aaaa good sens and stable system but a turn off pdk and tomrrow for tets night,turn on pdk and och!!!! My pdk came a half pkwer!!! 220v spark not sense ,just sense 100cm 220 v spark!! But 1.5 v spark sense a 150 cm!! Oh My God
please help me for recovery my pdk
i put a file for enginer to a good website longe range locator formus
thanks a lot for a very good website
Thanks❤️✨️

This is pdk for me
please help for recovery board
sense after spark 220v key lamp home,half distance sense

Could the sensor’s sensitivity or detection range being reduced by approximately 50% have been caused by exposure to 220V electrical sparks from a distance of around 10–20 meters?

Is it possible that these sparks may have damaged or affected the performance of some of the transistors or capacitors in the circuit?

I am also considering replacing the BC556B transistors with BC556C versions, since all the BC556 transistors I currently have are type B. Do you think this replacement is necessary, or could the problem be caused by another component or section of the circuit?

If there is any other possible cause for the reduced performance, I would really appreciate your help in troubleshooting the circuit and getting it back to its original sensitivity.

Finally, based on the current performance of the system and the tests I have carried out, do you think this device could realistically be capable of finding buried treasure?

Battery spark don't means something, only can check the sensitive of reeiver at same conditions. Make tests only with low voltage because H.V can produce different and strong harmonics with unforeseeable results.This schematic is the half of Alonsos PD (the basic is the Heathkit MD) and maybe can catch the phenomenon but it is very unstable at hight sensitivity

Thank you very much. Based on my experience working with this schematic—and comparing it to the schematic for the PD Alonso passive receiver—this model has less power and is ineffective in mountainous, high-altitude areas far from the city; even when adjusting the sensitivity knob, it remains silent and unresponsive. However, the passive section of the PD Alonso circuit does not have this issue and balances well in mountainous terrain.
