Pinball 2000 monitor, capacitor kit question
« on: January 17, 2011, 09:49:47 PM »
Hi guys
I will be getting the capacitors for a Wells Gardner 7300 Monitor (in a RFM)
now i have noticed that the cap kit on Pinrepair.com lists that there are 15 caps in the kit yet there are more than 15 on the board.
I assume that not all the caps are replaced or is the list missing some? I assume that the high voltage, high value caps are not changed.
If any one here has changed their caps on a pin 2000 monitor could you let me know if you replaced all the caps on the PCB or just the ones listed.
  
    * (3) 1 mfd @ 50 volts
    * (2) 10 mfd @ 63 volts
    * (2) 22 mfd @ 25 volts
    * (1) 33 mfd @ 16 volts
    * (1) 47 mfd @ 25 volts
    * (1) 100 mfd @ 35 volts
    * (1) 1000 mfd @ 16 volts
    * (1) 1000 mfd @ 25 volts
    * (1) 2200 mfd @ 35 volts
    * (1) 22 mfd @ 160 volts
    * (1) 47 mfd @ 200 volts

Thanks guys.

with ANY monitor the high voltage caps (from my experience) are the most likely to cause problems.

I wouldn't bother buying a so-called 'cap kit' unless there is some money advantage??

You can buy all of the caps you need from many suppliers in Australia individually.

I would avoid replacing the smaller value ones initially but certainly I would replace all of the high voltage ones.

I just finished a cap kit change for my Duck Scan.

I found the main cap 220uf 400V that was worn and expanding, replaced that. The picture was very slow to appear and its much better now.
I also found that it didnt really do much else for the quality of the image or the colours.

thanks private gump. I may as well change all the electrolytic caps since I have it out. I will post  a list of component numbers and values when I am done.
