    I do indeed very much like the memories I have of the 900IGC..

    I'd like to try a vintage 1.5 - 2g tracking big bodies ADC to see if my hunch is correct. I LOVE the XLM's I have, together with the ZLM and descendant Sonus Blue..
    Dag nam it Dave!

    That's one project I had in mind to do and report on AoS: my revisiting some fixed-coil cartridges of the '70s. Namely, the ADC 10E Mk. IV and 25/26. Also the Shure M55E and B&O SP6.

    So much to do - so little time!

    I have a 26 and it needs a negative mass arm to really become stable This one is fitted with a new unused stylus too and tracking doesn't get better over 0.7g. Once stable as much as possible, tracing of sibillance is poor by modern standards and way inferior to the XLM II, III and Phase 4 I have. I believe the 10E-IV is one of the 25 versions? (the 25 came originally with three styli). I have a couple of mk1 XLM's too and these also need the lightest tonearms out there to work properly.

    I had a VLM II but Alex had this with the SL150(0) he has. Slightly lower compliance and 1.25g tracking instead of .7 for the earlier delicate ones..

    I have an M55E with Ed Saunders stylus. Sound isn't bad, but not as neutral as all the ADC's IMO. I do still think it's better in many ways to the G800, but again, sibillance tracking is marginal where my V15's and even one of the two Supex's are fine on the same record (the Supex is used on the SL1500).

    I don't have a stylus for the SP6 (SP9 the best these days?) but do have a fully functiional SP12 and 14. the 14 is another bland one, but the 12 is a little bit special, as was the MMC20CL you covet. The SP12 tracks sublimely at 1 to 1.2g as clean as a whistle and with a very inviting sound overall, but again, the mid treble is severely recessed and that's a huge issue for me.

    I'm beginning to think that either variable input loading is needed on phono stages as well as capacitance, or at least variable eq, as needed on old 78's and some other 1950's records.
    I can't go on and I can't go back, I don't feel so matter of fact,
    I tried and tried to make good sense, What's the good to try it all again?

    Wasn't the ADC 26 very expensive for its time? I seem to remember it being the priciest in one of the early Hi-Fi Choice books.

    Hi Stu,

    Do you mean tracking weight? If so, it's 2.5g

    I do keep returning to mine every so often and this sample definitely prefers 2.75g. They were a bit variable by all accounts, so it'll depend on your sample I think. prolonged listening (yes Marco, I've persevered) gives a good midrange, but my upstairs lashup misses the treble.

    I've just bought a G820, possibly and hopefully a G820E (I don't think there was an "H" version) and look forward to trying this one out. the standard 820 was slaughtered in an early 'Choice yet the long demised "Super-E" version won a group test when it was launched.
    I can't go on and I can't go back, I don't feel so matter of fact,

    Just a little info I found on the G800 in the back of the Lenco GL75 instructions ( Dom Harper is doing up the Lenco for me at this moment - just waiting on one smalll bit). Some of you may have seen this already:

    "GOLDRING G800 & G800E
    For High Quality Amplifiers, these new magnetic stereo cartridges emplying the "free field" principle have an exceptionally wide and flat frequency response and excellent separation at all frequencies. G800-G800/H for slightly less sensitive amplifiers. G800/E (elliptical stylus). G800 Super E. Individually calibrated version for use at very low stylus pressures."

    Printing date of booklet 1970.

    What is/was the "free field" principle?

    I have a G800 which came with the TT & am going to get a stylus for it to try with the new Jelco arm on this table.

    Marco, if I use this with an 8.5 gram headshell with either a 2 or 4 gram weight added, will I need the Jelco heavy counterweight? Would add rather a lot to the cost!!
    Julian.
