Hey,
I have often wondered how they came up with these things
back in the day, when they are just now becoming somewhat
common.
A couple of weeks ago I posted on the QSO
forum about a partially assembled Johnson
Adventurer Kit that I got to complete.
http://amfone.net/Amforum/index.php?topic=35908.0 Anyway it had 1 missing part and 1 failed
cap. I added a 20K 10 W screen dropping "R"
and clipped out the failed 8 uF 700 V filter
cap. 1 of 2. The one hooked to the load side of
the choke seems ok but the one on the ripple side
got real hot real fast.
So I added a few appropriate caps to my order
and they came in today. I waited to make sure they
would fit in the tube before I did anything with
it.
Well this evening I opened the original
cap and was surprised to see 2 caps in series.
No equalizing "R"'s either. I know some caps
had a "R" built in but if these do I can't
read it. Maybe that's what wrong with him.
Pix 1 is what I pulled out shown above what's
going in.
Pix 2 is the finished product. + end
Pix 3 is the - end. The "Shot Shell" type
Roll crimp is a PIA to be sure.
So it's now a 12 uF 900V cap w/ equalizing
R's. Should last a while.
