Onkyo TX7830-nel a hangerogomb forgatasara a hangszorok membranjai ki/be mozdulnak.
Sziasztok. Van ez az Onkyo Tx7830 radios erositom. Mukodik rendesen, de ha a hangerogombot (jel nelkul) gyorsan forgatom fel vagy le, a melyhangszorok membranjai kifele ill. befele mozdulnak. He elegge gyorsan forgatom, a vedelem le is tilt. Lassu forgatasnal ez a jelenseg nem jon elo. Van a Tanyan s.m. rola, nezegettem is, de nem latom a kapcsolatot a hangero novelese v. csokkentese es a membranok mozgasa kozt. A hangeropotmeter es a meghajto ic. bemenete kozott van egy muveleti erosito, es ez galvanikusan le van valasztva ugy a potmeterrol, mint a meghajto ic-rol.  Ha valakinek lenne valami konstruktiv otlete, ne tartsa magaban. Koszonom.

ONKYO amplifier dolby surround, Problem with a Switching Diode
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.

Onkyo A8630 nem mukodik a bemenetvalasztas
Sziasztok. A cimbeli erositovel szenvedek. Hibasan vettem, csak az egyik bemenetrol mukodott. Mikor levettem a tetejet, lattam, hogy a bementvalaszto ic at van kotve. Rendeltem egy masikat, de ez sem akar mukodni. Mintha teljesen halott lenne, nem megy at a jel rajta - nincs egy bemenet sem kivalasztva. +- tapfeszek megvannak, a kapcsolat a kontrollerrel pin to pin leellenorizve. Nincs tobb otletem, szerintem 2 lehetoseg maradt: vagy a bementvalaszto ic halott, vagy a kontroller, bar a kivalasztott bemenetnek megfelelo ledek kigyulnak. Volt valakinek hasonlo esete?
