Yikes...not again!
trnsfmr....yikes..INVERT THE PLUGS.....are you SURE this would be okay? I will try it.....but, please confirm that it wont fry something....................
trnsfmr...you CAN'T invert the plugs...they have assymetrical spacing and can only plug one way.
trnsfmr....there is a small resistor on the meter pcb.......could this small resistor be defective? And if so, would it render the meter INOP?

The resistor is a voltage lowering resistor for the lights.
Not starting up the thread again....just concluding it a bit. The 9001 has all its knobs now!(The MIC level knob was missing). A new power meter has been installed....all 4 meters work now! AND 4 new original case screws are in place......the unit is back to stock.:thmbsp:
I have even tried the four channels once.....excellent sound through 4 old Bose 201's!
I think I may keep this baby..........we have kinda' become attached.....:thmbsp:
I know this is an old thread, but I just finished reading it. Congratulations Anderslober!! Job well done.
Also a small tip for you all, in this thread I have seen mention of a DBT (Dim Bulb Test), in a previous life I was an audio repair tech and used this quite extensively, but not as described. Because as Trnsfmr points out, there are some circuits that do not like to be run at a lower voltage.
What I had was a 60W bulb connected to both sides of a blown fuse, in the case of this massive repair, I would have placed it in the fuse (F07 I think?) that was blowing all the time. The same rules apply, if the bulb was bright, you have a short, if dim, maybe good and somewhat safe to replace with a fuse.
This would have saved on some parts costs, it was not always 100% effective, but it was pretty darn good.
Just something to think about the next time you have this issue.
Jim, I have been to your website, great info there, thank you very much for sharing, as I have a 9001 that I will be rebuilding sometime in the future, but that is a subject for another post...
Kev, love the pic of the Crown amp, just looked at the specs for them, WOW! That is one heck of an amp!
It was one heck of a journey on this project, it had me in suspense for the whole thread, I wanted to skip to the end to see how it turned, but I would have missed all the ups and downs. Great job all.
