Beag APtT 100 erősítőbe alkatrész beazonosítás
Sziasztok! Hozzám került egy BEAG APT 100 végfok a panelon nem szakszerű munka eredményként pár pontatlan értékű ellenállást,diódát cseréltek ki.A kapcsolási rajz alapján ki is igazodtam,kivéve a D113,114 zénerek típusa nem szerepel a rajzon(érdekes!)Most 5.6voltosak vannak benne,de ez nem biztos mert ahová sima dióda kellet volna oda pedig zénert tettek,egy dióda helyére pedig 2.2 kohmos trimmer potit-ez még érdekesebb. Köszönöm előre is!
CYRUS 1 power amplifier PCB and voltages
The Mission Cyrus 1 service information in the Internet did not include the PCB nor the voltages so far.
It is a bit difficult for you guys to repair it.
I have just repaired one and I took the time to redraw the PCB and measured the voltage to ease your job.

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.
