Should I remove the board and try replacing C161, or does that have nothing to do with the turn-on circuitry ? After it really powered on it took a little over 2 ampere idle current, like it should, and it played the music.Īfter removing the remote wire and putting it back after 10 seconds it took the amp 5 seconds to power-on, again with the 1.5 ampere idle current and clipping indicators lit during the 5 seconds.Īfter half an hour of inactivity it took longer to power-on, couple of minutes.Īnyway, these are exactly the same symptoms as the original poster's. During the time the cliping indicators were lit it took around 1.5 ampere idle current. During that time the clipping indicators were lit and there was no bias voltage, which I later properly set to 25 mVolts after it did power on. The amp had not been powered on for several months and it took several minutes before it really powered on. I think the capacitor which solved his problem (C170 on the Rubicin 1002) corresponds to C152 on my amp, which we did replace.Ĭould anyone comfirm it corresponds, I am not very good yet at reading schematics.Īnyway, unfortunately replacing the two caps did not do it for me. I somehow overlooked C161 which of the same value, stupid ! There are about a hundred screws to onbolt on this particular model to remove the board and have access to the cap's solderings, so I am kind of annoyed at myself for not seeing it in the first place.Īnyway, I have the schematics for the original poster's Rubicon 1002 as well as for my 10.2 I have the EXACT same problem on my Rubicon Class A 10.2Īfter reading this thread I decided to replace the 22 mf caps on my amp, namely C145 and C152. Only after it is off for a 1/2 hour or more will it take about 3 minutes to turn on.Īny ideas, where to look, what to check? Any help would be greatly appreciated. I also discharged almost every electrolytic cap on the board to try and duplicate the initial cold turn on, but the amp will turn on in 5-6 seconds.

I also replaced U106 but still had the same turn-on delay. I have seen in the past where old caps check ok for capacitance but the ESR is over 10 ohms and get very warm in operation.

I don't have the schematic for this amp and not sure if I had the cap in the mute circuit but the only electrolytic cap close to the SG3524 U106 IC was C168, a 22uf 16v cap which checked ok for capacitance but I replaced anyway.

My first guess was there must be a cap for the mute circuit that is bad or changed value. During the time that it takes to turn on 2 red LEDS for Clipping indication stay on then go out once the amp turns on. But once it is on if the remote wire is removed and reconnected it only takes about 5-6 seconds for the amp to turn back on. When the amp is off at least 1/2 hour or more it takes about 3 minutes for the amp to turn on (come out of mute mode). Perhaps someone has come accross this problem with this amp before. I have a SoundStream Rubicon 1002 amp with a turn-on delay problem.
