help identify parts!

[daRk_Kon]

hello everyone, i am repairing an American Bass VFL 100.1 car audio amplifier. the RCAs are blown and i need to replace them. when i removed the blown RCAs, i noticed there is a small orange part that is cracked but it has no markings that i saw and have no clue what this part is..

i humbly ask two things:
where can i find an RCA with 4 prongs? *see pics below

and where can i find and replace that little orange part?

i do have a multimeter if you need me to measure anything on the part to see if it works

Re: help identify parts!

Your photo's are a little bit fuzzy, ok a lot fuzzy. I think they might be resistors within a package. What is the part's designation?(part number printed on the circuit board. sometimes this is on the front or back or both)

on the board it says cf1

ceramic filters

Are you sure there are no markings? If not, you'll need service manual to identify.

Hi guys,
I agree with the other guy who commented.

The orange things are small encapsulated filter units.
Saw them in some exotic wireless intercoms.
In a pinch you can buy pass them.
The current pin out is
Input, Ground, Output.
So remove the part and jumper input to output
This kind of part is used mostly for EMI RFI issues.
On the bench you won't need it for a while.

As for the RCA jacks, there are lots of ways around that.
Exact factory parts may not be handy but something can be subed in.

Very often repair is not an exact art with old gear, and you have to work with what you can.

Re: help identify parts!

thank you for all your replies, i have searched for numerous places for this RCA, all i have found is the 6 pronged RCA rather than the 8 pronged.. so not sure how i can go about that.. but if i did i would have no idea of the pin layout... so i took another picture hopefully this is a little better quality than the rest...

also, where do i find the service manual cmj spoke of?

UPDATE i found numbers on the orange ceramic filter, 2220 A 10

Re: help identify parts!

Sometimes a search of the internet will provide a service manual, but I had no such luck.

Can you take a picture of cf1 front(markings) and back sides?

Re: help identify parts!

okay here are more close up shots with a better focus, the only things i can describe about the orange part are that 3 contacts, the middle contact is bare with the contacts on the sides have graphite or some material similar. only numbers on the part are 2220 A 10.
the markings are so tiny i could barely even read them... they only have numbers, no other markings that i saw.

you can also see the RCA 8 contact that i need to find, i have only been able to track down RCA with 6 contacts...

Re: help identify parts!

DK,
About the '8' prong jack.
Your confusing conductors with ground lug solder points on that connector body.
Give it a think and you will see my point.
Much luck.

so basically your saying the board is compatible with 6 or 8 prong contacts just that itw as an 8 pronged jack originally but its universal because where the ground is for the 8 pronged is also overlapped with the 6 ?

hrmm... so should i try and solder the 6 pronged jack instead of the 8 pronged? i have a 6 laying around here but i still need to figure out that little orange part, i looked on some spare amplifiers i had laying around but they weren't on those.
