If you look at what I posted yesterday you may find it useful.

Tracking force is generally 2 grams give or take a bit.
thanks,dont you mean posted today?
thats the first sign you know lol
My John Wright (line contact) rebuilt C4E tracks nicely at 1.8g in my vintage Hadcock 228.
I was going to suggest 10g tracking in a girder type of arm..... - sorry, I'm in one of them moods tonite...
ANY old Decca should have a service first before letting it anywhere near a precious vinyl collection. I have here a scan of a HiFi Sound review of this model (thanks to hifi dave's mag stash) and they suggest 1.5g* should be optimal despite Decca's recommendation of 3.5g downforce (vertical compliance is around '4' so this difference would barely make a change to the odd shaped 'cantilever.'), Sound was judged smooth but with marginal tracking at end of side if you weren't careful and a tonearm with a little damping was also recommended. Again, the 'direct coupled' nature of Decca sonics was praised. The response of the review sample showed nothing of the 18k resonances shown in many later models...
* [edit] - Please don't shoot the messenger - this was from a 1968 review and Decca were asked to confirm their tracking force suggestion. The reply was that the higher weight was used when setting up for best separation figures. I am aware that top Deccas had revised suggestion for tracking force of around 1.5 - 1.75g as shown above and I seem to think the cantilever and suspension was altered to take this into account, but I can't remember where I read this, so pinch of salt time until I can verify it... P.S. Many years ago when I was starting out, I had an original Decca Blue London which tracked superbly at 1.75g or so. T'was a bit too much for me at the time, but I've often wondered what it would have been like in a better matched arm and with a properphono stage with high overload margins able to take the hf dynamics...
that will do nicely!
1 slight concern is the last sentence,not to be used with ferrous tt's, guess what the plinth is made of on the rock2 :uhho:
