I have and found most of the voltages as indicated on the circuit diagram, till op amp M 5218P; are near those specifed. The output on the centre of the two power transistors of both the channels are also alright.
While looking at the voltages on test points as mentioned on the page 7 for setting up quiscent current, these cannot be set.
Bit of history, the amplifier was lying unused for long time. Nothing in it has burnt. It was never opened earlier than this time, couple of days back.
While I was probing for voltages with DMM, with probe on collector of TR413 one of the fuses blew up. Later same thing happened on the other channel as well.
With the above as background can a Good Samaritan figure out feasibility of repair.

Sziasztok !
A fenti hibán hogyan lehetne segíteni zöld színű fűtőszálas kijelző van benne pontosan nem tudom megnevezni a típusát. a fűtő fesz 24volt helyett csak 23 volt ez lehet a gond?
Üdv nektek!
Hi,
I am working on a Luxman L100 belonging to a friend. I noticed the following problems.
a) It takes about 12 to 15 secs for the relay to turn ON.
b) The relay does turn ON but both the "winker" bulb and "ON" bulb do not light
(both the bulbs are OK)
c) The "touch MUTE" is not working.
d) When switching on the 10Hz low cut filter, the relay cuts off and does not come ON until the switch is set in the centre(bypass). Can someone familiar with this amp, please help me out
Thanks
Carlos
