Harman Kardon TU911A
after working on schematic i found D205 diode faulty replaced it, now signal show up, searching stations also very well but very low signal which cannot catch them auto mode... if i arrange station freq. manually, then can listen very tiny play which if i open volume very high then sligthly hear the music etc..
how can i cure this issue,,
i almost replace all electrolitic caps with new ones, still same low signal issue
Hi! Is the +11.6V….12V (+B) present on FE101 - pin8?
Are the voltages of the Q201 correct?
there are generally two types of drawings in SM, with and without AGC adj. and usually FE101 consist an input antenna amplifier too (can't find detailed schematic in SM).
