RCF aktív hangfalban ismeretlen IC
Szép napot Tisztelt Kollégák! Egy RCF gyártmányú, ART708-A típusú (Digipro600) aktív láda erősítőjében lévő SMD IC-ről nem találok semmiféle dokumentációt, leírást. Ami az IC-n szerepel: AEB DPI 829P. Esetleg tudna valaki segíteni ennek az alkatrésznek a beazonosításában? Üdv: István

Trouble with TL072 op amp in audio preamp build

Hi everyone,
I'm experimenting with the TL072 in a small audio preamp project, but I’m running into some confusion. The circuit powers up, but I’m hearing noticeable noise and distortion when I increase the gain. I’ve double-checked the wiring and power supply (±12V), and the pinout seems correct.

Could this be related to the package type (SOIC vs DIP) or do I just need better decoupling caps? Also curious if there are drop-in equivalents that might perform a little cleaner.

Any advice would be really appreciated!

jbl charge 4 ki-be kapcsolgat
Sziasztok.
Van egy JBL charge 4 boombox,ami reset és szoftver frissités után is ki-be kapcsolgat időnként,magától.
Key panelt lehúzva is marad a hiba.
Született már erre a kukásitáson kivül valami megoldás?
Köszi
Taki
