Sennheiser Freeport FP35 C-EU rádiós mikrofon probléma
Üdv! Adott a címben szereplő eszköz, a probléma több részből áll: - a mikrofon a legapróbb kézmozdulatot, taperolást, mocorgást átviszi; - amikor a kapcsolat megvan, és a vevő is jelzi annak meglétét, a vevőegység doboza szinte egy érzékeny mikrofonként viselkedik, kicsi megkocogtatva hallani a hangfalakban ennek a hangját (a mikfrofon kikapcsolt állapotában ez a jelenség nincs meg); - a mikrofon kikapcsolásakor, tehát amikor megszűnik a rádiós kapcsolat, egy elég határozott kattanás jön a hangszórókból! A vevő rádiós részében találtam egy smd kondit, ami a zajokat beszedi, ezt nagyon óvatosan is, műanyag eszközzel érintve, piszkálva, rögtön hallani a mocorgást, elég hangosan! Ez valamiféle hiba, selejtes alkatrész, vagy mitől lehet? Elég idegesítő, amikor áthelyezem a dobozkát máshová, és közben minden ehhez kapcsolódó mozgolódást hallok! A mikrofont is szétszedtem addig, hogy a benne lévő nyákot kocogtatva, ugyanúgy viselkedik, mint a vevő! Bárkinek bármi ötlete, tapasztalata, véleménye, kapcsolási rajza, kérem ne tartsa magában! Köszönöm :)
Help with Panasonic SG-K2000/SG-H10 amplifier issues

Hello everyone, I'm having issues fixing this vintage stereo system, its amplifier boards seems to not be amplifying. The audio comes out at super low volume with the max. volume setting (the pot. works correctly). At first I had 20V and a constant hum coming out at the speakers output (saturated amp. I supossed). I changed the electrolytic caps., the 5218P component (TL082 replacement) and the NPN/PNP C1815 and A1015 transistors (this last thing helped with the amp. saturation and I do not have any DC at speakers now), but now the audio comes out super low. I measured the D1265 transistors off-board and they seem to be ok. Can anyone shed some light? Thanks in advance
