Dorm room setup: Beogram 3400, Beomaster 2000, Beovox S80.2

Finally back to working on this. I did make the necessary connections with the new capacitors Checked for cracked solder joints, but haven't found any. Checked the trimmer in the reset circuit, its still in one piece. Here is a video of unit attempting to turn on, not sure if this helps at all: http://s665.photobucket.com/albums/vv19/BoxOPwn/Beomaster

Capacitor C1 was shorted, and I replaced it and C10. It turns out my tests on the original rectifier were incorrect, as I compared the original to a replacement. I decided to put the original rectifier back in the unit. The beomaster is no longer blowing any fuses, but it is still not operating correctly. When it is plugged in, the relay will click

I have been unable to work on it , as I am currently at university. My winter break begins next week and I will begin repairs then.

The Jack is not shorted, but I plan to remove it. I did in fact remove the rectifier for testing, but perhaps my testing methods were incorrect.

Thanks for clearing things up Dillen, looking at the schematic now this makes much more sense. I beleive the capacitors you are refering to are C1 (3300uF 16V) and C10 (2200 uF 40V).

I should also mention that a previous owner soldered wire to both ends of D3 on PCB 6. The wire exits through the bottom of the Beomaster, and is terminated with a 3.5mm jack. I beleive that PCB 6 is for motor control. What possible purpose could this serve?

I recently acquired a Beomaster 6000 (Type 2253) in non-working condition. Physically it is in great shape, but it will not power on. Inspection revealed that Fuse 2 was blown. I thought that the bridge rectifier (16D7) might be part of the problem and after testing, it was found to be faulty. I am considering replacing it with this part: Vishay 625

The stands for my s80.2's have small plastic feet on the bottom, I don't know if these are found on all of the different stands. One of them is missing from my stands, and I would like find a suitable replacement. Does anyone know were such a part could be found? If I can't find a similar part, I could easily just make one from some plastic

Would you happan to know the diameter of the dustcaps on these woofers? The speakers will not arrive until next week, so I cannot measure this as of yet, but would like to order the parts soon.
