I have a Onkyo DX-7333 CD player, which sometimes doesn't recognize CDs. I don't think it's a laser pickup (KSS-213C) problem, because when it recognizes the CD, it plays it without a problem, even very scratched ones. The next thing is, it should play CD-RWs, but it doesn't even recognize them. I think it needs adjustment There are two pots on the main PCB - Focus Gain R123 and Focus Offset R112. Also there are two test points: TP1 4 pins, first pair labelled Tracking Gain, second pair Focus Gain TP2 2 pins labelled RF Out and VC But in the service manual is no description, what should be measured on the test points and how to set Focus Gain and Focus Offset. In the attachment is a cut out from the schematic, where the test points and adjustment pots are. Please if someone knows, how to?

Keresek Siva PPA-1600-hoz kapcsolási rajzot! Fontos lenne,ugyanis annélkül nem tudom megjavítani! Előre is köszi!

Does anyone have a data sheet for a Sanyo STK8800II? These were used in Yamaha R-100 receivers. Or does anyone know of other amplifiers that used this chip? It is a 14 pin, dual supply, single channel power amp chip with parallel output transistors, rated for at least 100 watts, probably more. Thank you,

Sziasztok!
Tegnap hozták ezt a erősítős hangfalat, olyan hibával hogy nincs hangja. Próba után be sem kapcsol, a graetz után lévő icé ledobta a tetejét, ami nincs meg, így kellene az ic típusa. A hangszóró átmérője 31cm, de rajzot még nem találtam hozzá. A képeket is felteszem róla!
