Ohhh today is a rough day...
Last night I went to turn off my Rotel RB-1090 amp and when I pressed the button.... well the light stayed on... which I thought was odd. SO my thinking was, I missed pushing in the button all the way and it didn't turn off, so I bent over again and pushed the power button. However, when I pushed it, it went to the "ON" position... Thinking this was a little bit odd I pushed it a third time and no luck. The amp would NOT turn off!
Due to the lateness of the evening and the fact that work comes very early in the morning, I reached back and pulled my brand new power cable (Blacksand Audio Violet Z1 MKII - and yes this cable is making a very nice difference with this amp) and waited till today to look at the amp.
Unfortunately (which I think Rotel should reconsider), I bought this second hand off of Audiogon about 2 1/2 years ago, so no warranty for me. So with that thought, I looked around on line (and with talking to Tyler at Rotel) about getting a service manual and opening the thing up and trying to fix/see if the power button got damaged some how.
Now I take IMPECABLE care of my equipment and since I got it, I've only added one minor scratch to it, otherwise, I think there were about 3 almost unseeable scratches when I got it... so this thing has not been abused. So I was thinking the switch might have gone bad...but had no clue.
I started opening up the amp trying to get the face plate off and was very successful at doing this however one set of wires that ran into the front heatsink was not quite long enough. So in my attempts to free the piece I needed, I broke one set of wires. :evil:
Knowing that I would have to get it back on, I decided to try to follow the wires deeper into the amp and realized there was a board right on the bottom left (looking at the front of the amp) that they ran to. Well it looked easy to get out so I started undoing more of the amp and well I found this...
I'm guessing this is most likely the problem and I'm guessing not the switch... After seeing this and knowing I definitely will be without the amp for a week or so... it's already killing me! Luckily I had both a 1080 and 2 channels on the 1095 that I could use so I'm not completely without music and the HT... however after sitting here listening to music while I type this and do a few other things... the 1090 is definitely in a another league compared to the 1080.
The 1080 is very similar, but doesn't have the smoothness and power of the 1090. Low end has definitely suffered the most. But also the realism of instruments is not quite there with the 1080 (course that could be due to non-use for almost 2 1/2 years.... :/
So knowing I would be without the amp for a week or two.... I decided to take the rest of the amp apart. I'm thinking that I might replace some of the wiring with some better quality wire, most of the internal wiring is 14 to 18guage and looks like possibly 12 going to the binding posts...
The only thing I know for certain is I'm going to put some Deoxit Gold on all the connection points to help (might as well as everything is this accessible) :B
Anyways, I figured everyone would like to see the thing disassembled! :E
This is what's left of the chasis, I'm going to take the back off (4 or 5 screws on the bottom) and then decide what I'm going to do with the power connections and speaker connection cables.
