Hi Rich

I certainly did, however a couple of bubbles still appeared, to remove I jarred the unit on the bench, they sunk. I then topped the area up with more potting.

I think its OK, well fingers crossed its the first tripler rebuild I've attempted.

Its now dry enough to trim which I have just done. Now put to one side for a couple of days for it to fully cure throughout.

The diodes should be fine.

If you read Tony's previous post he stated the ones he supplied me, are the ones used in 3000/3500 triplers. BRC 3000/3500 triplers are virtually identical and use the same number of sticks as the 2000 (5).

After 60hrs of curing I couldn't wait any longer as the suspense was killing me. This afternoon I tested the rebuilt tripler in the Ferguson 3700, happy to report its a complete success :thumb

Maybe VB has come up with Chris's next challenge after all we all no how good he is building sets from bits so how about a "Honda style TV parts ad" as a challenge ? :qq1

Excellent result there- looks as though my pessimism over leaving it unpotted for testing was decidedly misplaced! :aad That compound looks very much like the stuff that Schaffner mains filters are drenched in- has it set hard or soft? The Schaffner stuff sets pretty hard, making it difficult (though not impossible) to dig out for changing Rifas...

Soft, so if I ever need to repeat the rebuild, it will be a simple dig out once again.

I have one other to rebuild, however that needs a VDR and I've yet to find a replacement or figure our a substitute.

This may sound silly but once you've finished with the tin of silicone, seal it in a couple of thick bags and put it in the freezer.
The catalyst can be kept elsewhere as it lasts for a while but the low temperature will prevent the rubber self-condensing and should at least double the shelf life.
