Wifey Awoke "Hoo Rah"
After a little search through Wifey Domain it appeared, a multi pack of PTFE tape, to the words " I never put that there"
I was back on track.
AS BEFORE FOLLOW THESE STEPS AT YOUR OWN RISK.
Step 1,
Removed slot head screws from air inlet, I then cleaned the air seal residue from earlier attempt.
Step2,
I replaced the screw back into the hole leaving the countersink exposed so I could wrap a small amount of the PTFE tape around it, about
10- 20mm in total length, leave the initial length longer and trim when done.
Apply a little pressure to PTFE tape by tightening the screw a little.
Step 3,
I wanted a better control of the re-gas procedure to get a better pressure behind the diaphragm, so I put this method into practice.
The tweeter had a sticky soft foam disc set behind it in the enclosure, I took the soft foam and folded it in half. I then used a scissor to cut a
small hole in the centre, two little mirror image "V" cuts allowed a hole about 10mm to be achieved.
I put the foam pad on the back of the tweeter with the air inlet screw sitting exposed in the scissor cut hole.
I then took the tweeter out to my car.
Step 4,
BE VERY ALERT AT THIS STAGE AND BE QUICK TO REMOVE AIR NOZZLE FROM FOAM SEAL.
I plugged in my 12V tyre air compressor, I placed the hose nozzle onto the foam covering the hole and air inlet to create a air seal.
Whilst watching the Gold Peizo Diaphragm, I switched on the compressor. The re-gas is immediate, less than a second in time.
Pull the nozzle away from the foam. Add a little more pressure to air intake screw.
Check the Gold Peizo Diaphragm for tension, I chose a taught skin with a quick to reset reaction when pressed.
To achieve this you may have to apply the nozzle to foam and air intake a few times, applying a little extra tightening to the screw after
each air intake.
When the desired tension is achieved on the diaphragm surface, fully tighten the air intake screw.
The second tweeter will be a breeze, just be sure to check each tweeter has a similar surface tension.
I encourage all those who watched there hard earned outlay for the HD-3P evapourate, follow these steps and new life will be breathed into
this Very Good Tweeter.
P.S
Oasis are filling the house with their tunes, and it sounds great where ever you are, my Ridgeback Dogs have stole the listening sofa.
