Installed an inline suppression filter to the power supply and didnt make any difference i am thinking the distributor has such a strong spark that nothing is going to stop the issue

Hi

Try disconnecting the charging system, that maybe where the noise is coming from. If that fixes it you may need a suppressor on the charging circuit

Does the noise go up and down with engine revs??

make sure everything is earthed well..

separate perfect earth connections on everything..

means scratching the paint off under each connection..

also, could try attaching an earth lead to the distributor or engine..
check the earth strap at the nose of the gearbox to chassis..

Your spark plug leads - are they resistance type or wire type?
I'm guessing You have a low resistance spark plug lead system

beetles normally have a resistor in the distributor rotor plus in those bits that sit on the spark plugs.. but I'm guessing its an earthing issue... which is being picked up by Your amplifier etc,,

cheers

kinda strange its like the amp is being clipped

I have Taylor Spiro Pro 8mm Plug Wire Set - Blue leads

Will have to check all earths so is the earth strap at the front of the gearbox?

Hi Paul
You should be able to see it hanging from the chassis to the nose of the gearbox near the front gearbox mount..
I made one out of a new long earth strap I had, I soldered each end and drilled holes
it needs to be shiny on the strap and the chassis metal so it earths out to the chassis metal, not thru the bolt..
Use a new zinc plated bolt and flat washer..
Many of these straps are missing these days and the flow of electricity has to go thru the gearbox gear shifter etc to earth out..
I've seen headlights go dim when changing gears... lol

earthing problems arise due to a car being painted etc.. as its natural not to want to go scratching the paint off.. lol

cheers

best of luck

doubt if it is earthing if everything else is working fine

first thing to go would be the battery not charging or not starting properly

I know you are using Taylor Spiro Pro 8mm Plug Wire Set - Blue leads

But are they noise suppression leads??

Taylor Spiro-Pro 8mm Custom Fit Spark Plug Wires

Features
Spiro-Pro's two-layer 100% silicone inner core & outer jacket keep the wires flexible for the life of your vehicle, maintaining its vibrant color with heat protection to 600º F
Spiro-Pro wire consists of a highly conductive spiral wound core with a stainless steel wire covered with conductive fluorocarbon material
350 ohms per foot resistance provides more fire power to the spark plugs than OE resistor core wires and has up to 10 times less resistance than standard resistor core wires
Spiro-Pro eliminates radio frequency interference (RFI) and is recommended when using multi-spark discharge electronic ignition systems and other electronic components

Looks like they are OK then Paul...

I like those leads but too expensive for Me.. lol

and I wasn't sure whether they were the suppression type or ones used on race/drag cars which don't need to be suppressed etc...

Looks amazing Paul,notice that vintage didn't fit a breather box setup for additional breathing to releive crankcase pressure

Isn't the hose between the carby and case sufficient?

new motors don't have a lot of pressure to get rid of.😊

It's been a while since I posted an update, yesterday Rosie went to Vintage VW for a service as well as a few bits and pieces, as usual Boris, Mike and the gang did a fantastic job, couldn't be happier.

Next upgrade will be replacement of the rear deck lid with one with 4 vents then I can remove the stand-off
