Klipsch ProMedia 2.1 Amplified speakers


Original problem is no sub woofer output. Been through this one and recapped it and the common 2 burned 1K (R16/17)
resistors are replaced but the sub is still not responding. Volume control potentiometer is a common issue on these but
the L-R spkrs sound good.

Went by this webpage on the repair:
https://christopherbradshaw.net/The_Project_Bin/klipsch%20promedia%20subwoofer%20repair%20-%20page%201.html

On the schematic there is a sub-relay (sw101) powered by +V_HF line it
maybe is suppose to be +V_LF ? Without the relay coming on looks like the sub is disconnected.
The zeners (D03/04) that give +/- Vcc to the op amps seemed way off so I replaced them and the voltages seem much closer.

Theres also a sub-mute line on p104 to p101. Power supply shows the LF mute relay and interconnect diagram says it
gets fed from the LF amp. What is triggering the mute? I dont see a mute button anyplace.

Skytec spl 400 erősítő recsegő, pattogó hang a hangszóróból.
Skytec spl 400 erősítő recsegő, pattogó hang a hangszóróból. A jelenség a hangerő szabályozó változtatásával halkul, illetve erősödik. A bemeneten semmi nincs. Az előerősítő táp soros ellenállása megégett. Feltehetően az RC4558L IC hibája okozza. A baj az, hogy ilyen IC-t sehol nem találok. Ez egy nyolc lábú inline tokban van. Van valakinek ötlete, hol lehet beszerezni az IC-t? Előre is kösz.
Denon D-Link kábel lerás (pin-out)
Sziasztok!

Két Denon DN-S1200 szeretnék összekötni 1 db RJ45-s kábellel (nem nem sima lan hálóztati kapcsolat).
Viszont nem tudom a lábkiosztást. Nem találok rá pin-out konfigot.
Tudja valaki hogyan kell krimpelnem az RJ45 csatit a  cat5e kábelre?
Köszönöm.
