STK4036X helyettesítése, akár helyére építhető végfokozat tervezése.
Sziasztok. Adott egy Grundig v303 erősítőm. 2db STK4036X található benne. Már nem gyártják nem tudom beszerezni. Építeni szeretnék a 2db STK helyére 1-1 panelt. Milyen kapcsolás lenne ide megfelelő? Csatoltam képet az erősítőről. Előre is köszönöm. Üdv: Csady
STK helyetisithető
Szép estét kívánok.

Kérdésem az lenne,hogy az STK404-070 helyetesithető STK404-050 el.
Én nem látok külömbséget. Az 50 illetve 70 telyesítményben külömbőzik egymástól

Üdv András
Trio-Kenwood: KR-3010 [Radio] S.N.962845 / Does not work, the final floor and prefinal floor defect with many burned component/

I greet you! I would need the scheme of this "vintage" amplifier that needs to be "restored". The problem is that in the prefinal and final floor I have many "fried" resistors well, their value cannot be identified.I replaced the defective transistors: 2SC1509, 2SA777,2SB690 and 2SD 796 (each 2 pcs.) and the electrolytic capacitors adjacent to them. I could not go further because of the carbonized resistors that I do not know their value (I can only guess that they are values small, in the order of ohms). The schematic diagram I downloaded, from the address received by the kindness of a colleague is not complete - it is a single page (missing Q29-Q30-Q31-Q3 and resistors R115-R116-R117-R118 which are completely carbonized, at other resistors I could see their value).Thanks in advance!
Finally, I found the missing part

If stuck in the repair and you ask questions, please do it as follows: - Details: Give the exact model number of your device and the chassis ID (if there is). - If possible, please attach pictures of the appliance. - Anamnesis: Write down the exact symptom. If hard to describe the symptom, it is difficult to verbally defined clearly, attach pictures or sound of the phenomenon! - Tell what was you have done so far: search contact error, which parts has examined or changed yet, etc... The incorrectly named topic suspended and will be deleted after 48 hours! Suspended state while others are not able to comment until you correct the address. Subsequent repair of the defective title (within 48 hours) by clicking on the "Edit" tab can be carried out.
