Yes, many thanks Bob!
At last I can try some other cartridges. There must be more to life than a Denon DL160 (as good as it is)

Arrrgh! Is there a problem with the WD SUT's by any chance?

I only ask 'coz one of mine has just let go. Are they fixable?

Looks like I've lost the secondary on it, it reads about 1.5 meg which gradually increases... I got bored and gave up when it reached 2 meg.

I've only just got my 12" PU7 fitted too, why do these things happen just when you've just got all excited 'n stuff!

Bah!

I assume this is similar to the problem I had with one of mine 3 years ago? (was it really 3 years ago?) http://www.world-designs.co.uk/forum...ead.php?t=4770

I'm happy to report that the replacement, and indeed the one original stepup are both working fine, but if there is a simple fix for a potential problem, I too would like to know how please=)

Hi Shian & Dik, the problem that I have found is the secondary winding is soldered, what seams to be at a centre tap, and it corrodes at this joint, I have put back into servis 11 to date, with 1 f##k up, to undertake a fix, you first need to remove the cap which is soldered, then using a heat gun, melt the wax inside and remove the transformer, now here's the delicate bit, follow the red and black wire to there temination and very gently cut the white tape inbetween the two cables to reveal the two ends that are soldered together, you now should now have the problem, clean and resolder and cheak for about 680 ohms, push the tape back and reasemble. oh and a good pair of eye's is mandatory. Good luck. BOB

Hi all,
I would be very interested to know which transformers these are.
The cylindrical ones or the cubical ones?

John

Thanks Bob, sounds tricky and fiddly=)

John, The problem I had was with one on the very first phono3 cylindrical ones. WD very kindly exchanged mine for another identical cylindrical one, even though it must've been well out of warranty. Mine continue to work perfectly ever since... I was just being nosy and cautious in case I ever have a repeat problem.... not that I'm expecting one.
