Filter CAPs - When to replace, possible to increase value?
Some of the 25" wells gardner K7000's have raster size change with a bright screen which is driving me crazy. I have fully recapped the chassis's in question except for the large filter CAP on each one. Is this the most likely cause of the bright screen image size increase? Some of the tubes are weak and I am slowly trying to find tube donors to deal with this.
Does a weak tube also increase this affect due to the higher driving voltages?
Most of my other games that are 19" are k4900's and they do not seem to have the problem really at all.
Are k7000's or 25" monitors more likely to have this bright screen raster growing problem?
I know the voltage of the CAP must be the same or higher but what about the value? Is increasing the value possible and will it minimize the effect? I ask because I have been removing some expensive large capacitors from dead APC UPS power supplies that I found but probably is best to replace with the same value I assume.
Buffett - what do you think if you see this post? Do you have any for sale and what is your opinion?
thanks,
Nate
