Sziasztok!
Most hozták azt az erősítőt, hogy nem lehet bekapcsolni. Szétszedés után a biztosítékok épek, ellenőrizve a transzformátor a kimenet jó, de a primer szakadt. Ez toroid trafó, és van-e benne hővédelem, de ki van öntve az alja? Ki javítja ezeket a trafókat az országban? Teszek fel képeket is!

Tisztelt fórumtársak!
Tulaj állítja, hogy sötétben nyomkodta az előlapi gombokat, majd később azzal szembesült hogy 200kHz-enként léptet adó keresésekor.
Használatit nem találtam, bízom benne hogy valaki tudja hogy hogyan lehet visszaállítani a keresés 50kHz léptékre, köszönöm.

Hi guys,
I am trying to repair a Digipro 1500s psu that had a really bad short due to a drink spilled over the sub S30.
Thanksfully it only shorted one of twin modules but unfortunately the PIC18LF2321 is shorted and i haven´t got the .HEX to program a new PIC.
Does anybody have some kind or information or even a SM? The 1000s it´s similar but instead of having a PIC it have an 555 ic.
Thanks in advance.
Greetings!!
PD: If somebody have a defective module and want to sell it, we can get in contact.
