Sziasztok!
Az a gondom ezzel az 5 CD táras modullal, hogy az 1-es /legfelső/ fiókba nem tolja végig a tálcát. Többször is próbálkozik. Itt a legnagyobb a kar áttétele. Kézzel rásegítve végigmegy. A szíj nem csúszik, szorulás nincs. :hmmm:
Üdv.:Ckó
Hi everyone
Could somebody tell me if I can replace a switching diode to another one, the one installed in the onkyo is a 1SS252 and is 10 times more expensive that a 1SS355.
Usually I order the same but they are pricey (around 10.00 usd for a 100) and not commonly used, not many sellers.
For the 1ss355 every seller on line has it in stock and it's around 1 to 2 usd for a 100.
Ans they are available locally, not in china waiting 5 weeks for the part.
Thank you.

Üdvözlet Mindenkinek!
Ez a leges legelső topikom.
Végső megoldásként fordulok hozzátok a problémámmal:
Sikerült hozzájutnom a fent nevezett magnóhoz, viszont amint levettem a hátlapját vált láthatóvá a nem kis gond! Két hangszóró rákötve a jobb végfok IC-re, a bal végfok IC-nek hűlt helye, és ami legrosszabb a környékén a panel szét égve. IC-m még lenne, de a felégett panellal sajnos nem tudok mit kezdeni. Varázsló nem vagyok.
Röviden: Nagy szükségem lenne a kapcsolási rajzára! Tudom hogy fizetősen lehet vásárolni a neten, de ilyet még nem csináltam. Ha esetleg valaki már vásárolt így, és ezt is meg tudná szerezni, annak kifizetem a költségét!
Köszönettel: Mátyás
Hello!!
Ha valaki el tudná nekem küldeni az Onkyo Tx-7430 erősítő kapcsolási rajzát nagyon megköszönném :)
