Amplituner Philips 741


Recommended Posts

buna seara tuturor colegilor

am arestat evident din talcioc acest amplituner 

PHILIPS 741 tip 22RH741/33P

toate bune functioneaza avand un sunet deosebit

dupa o curatare si inlocuirea tuturor becurilor inclusiv cel de stereo acesta din urma se incapataneaza sa ramana stins desi semnalul e foarte bun si auditia perfecta

decodorul este facut cu integratul TCA 290 A

as avea rugamintea daca are cineva o schema

conzi electrolitici masurati au valori foarte bune avand in vedere vechimea anul de fabricatie fiind 1975

va multumesc mult

multumesc mult d-l ALVIN...aceea este schema si tare banuiesc ca s-a dus intergratul.....cel putin partea care alimenta becul....acolo am gasit un bec de 6 volti la 200 mA ars comparativ cuun curent de max 50 mA admisibil conform schemei.....in gol apar cei 15 volti dar in sarcina chiar cu un led apare un flash si cam atat

da...functioneaza cu un led si functioneaza bine

va multumesc mult....nu gasesc bec de 6 volti si 50 mA dar ii voi pune un led de 10 mm alb si va fi excelent

cu respect
