help for repair minelab relic hawk

[luigi cataldi]

buongiorno
Sono
composta da Luigi Cataldi Rivenditori Italia e Repareir Rilevatore di Metallo
Ho un Riparo Minelab in riparazione, è un vecchio metallo e non trovo informazioni in linea sui componenti da sostituire, ovviamente eliminati tutti i processi è difficile .......................

certamente c'è un transistore bruciato e non leggi il codice

se potete aiutarti sarò grato a te

The only information I have are a few schematics of the Relic Hawk. Some have transistor numbers and some don't.
These might give you a clue.

Good evening
thank's Mr. Quiaozhi maybe i found the missing transistor in BC 557 that is connected to the diode on the coil TX, as soon as I make the necessary changes of components I update you

Mr. Kt 315 if you need better photos, for me there is no problem tomorrow I do other with a photo camera 15 megapixel

thanks guys problem solved
I changed the bc 857 and the brs 51 to the audio

I don' think the file "re=.jpg" is for the Relic Hawk. In fact, I can't see what's driving the TX push-pull stage.

Interesting circuit, though

yes infact "rel jpg" it's schematic the musketeer
