Panasonic AG-1980P Y/C board recap? (replaced capacitors)
 
i count 37 on a VEP03D52

the older style VEP03B70A boards are a little different

here's what i got...

Panasonic Replacments
(6mm diameter on the big ones)
(5mm diameter on the small ones)
$14.56

look correct?

thoughts? suggestions?

(figured this might help someone else coming up with parts list, thats thinking about doing it)

15 bucks? isnt that a lil cheap

did i pick the wrong ones or something? is there something better? what do you recommend?
thanks

Electrolytic capacitors aren't that expensive compared to polymer or tantalum, the difference is the latter will basically last forever. I would go for the 105C rated parts though, as they last longer. No need for bi-polar caps unless the application specifies them.

thanks your reply

im so confused when it comes to ordering caps...

so many choices, i would like to get something that lasts a little longer

wouldnt it have to be the same diameter?
(so it fits in the same place)

would you be so kind as to give me an example of what youd recommend?

heres what i got from the 1980P manual

so your saying go with the "Aluminum Organic Polymer Capacitors "

what about the ESR and Ripple Current, does that make a difference?

x77x 10-12-2015 09:02 PM

my finished shopping cart, using organic polymer where ever i can

The original defective caps lasted for about 10+ years. They were a defective formula. New caps should last much longer. While physically larger caps will fit in many of the sites, they will not fit in some, so if you plan to use larger caps, check spacing.

Bottom line is how long do you plan to use the AG-1980 after you re-cap it.

I had some gear from the 1980s that used tantalums, they started to fail after ~10 years. They would pop when the gear was powered up. There are no guarantees, just probabilities.

OH NO!

got my order today...
the Aluminum Organic Polymer Capacitors
are in a anti moisture bag!

anti moisture!? im guessing i bought the wrong ones

if they are sensative to humidity, then they cant be for VCRs?

it would be nice if NJRoadfan would clarify, what he meant by polymer...

should i be worried about it? did i get the wrong ones?

HELP!!!???

NJRoadfan 10-21-2015 07:55 AM

Link is broken. They are likely fine, normally electronics are stored in antistatic bags with desiccant packets to absorb moisture. Modern computer motherboards use these capacitors, so they can deal with normal household humidity levels without a problem.

x77x 10-21-2015 08:13 AM

but that is what you meant right?

or did you mean go with the square polymer ones?

heres the link again

NJRoadfan 10-21-2015 09:48 AM

Those are the ones. Specs are better than the original units. They should last the life of the machine at this point.

x77x 10-21-2015 03:47 PM

SUCCESS!!!

no more wavy lines!

im not gonna lie, it sucks!!!
took me 2 days, one to take um off, one to put the new ones on...

saved myself $120, but you know what...
with all the frustration involved, your better off send it to someone else to do =P

NJRoadfan 10-21-2015 03:57 PM

Its good to know that substituting polymer caps works perfectly in this application.

x77x 10-21-2015 04:35 PM

you be the judge...
