Please note jamie.
The photo I have posted here is the original set up for 11 77 78.
Neither of these cartridge work ,their 50 years old and not restored yet.
Just I have some 11 78 stuff waiting on some veneers , money, time, before I can continue with the restoration of the complete unit.

Yes I bet it's a tricky operation, the scales would need to be .01 gram scales, which would give a good indication. These older cartridges were rated for higher weight than the newer ones, around 6 grams, which would be more practically achievable from an apparatus used to be 10grams max, shouldn't be too radical an adjustment (I hope) Yes it's expensive but hopefully one-off expense, allowing myself a couple of days to think about it first in any case.

Yes a tricky operation no doubt, would need scales rated at .01grams, the older cartridges handle more weight than the modern Tetrad, I should be able to hose it down to around 6 grams which the BSR can handle, it has an adjuster screw, but 3 grams might be too much to aim for the changer might not work properly!

You can set it up by balance on the arm, take the cartridge out leaving head on,Then find zero Gravity point on the tone Arm.
Then put your cartridge in the head and thats going to be a good start point

Yes it ain't cheap, but being an older style it's good for at least 6 grams, which would be easier to get with an RC 121 than 3 grams, maybe a kitchen scale rated at .01 gram would be helpful, not an easy task I'm sure but hopefully I can adjust it into the ballpark without stuffing up the working of the record changer...

Ok Pete that sounds good, basically get it balancing without the cartridge, shouldn't be too hard. Sorry about the similar post replies, I was looking on the first page and thought they'd disappeared! All good, I might go with the more expensive cartridge as it would be better suited to the weight of the tone arm. Cheers.

The stylus pressure guage that I used as an apprentice was produced by Garrard, and was probably given out as a promotional freebee.

It was basically a large letter G with a little arm onto which one placed the stylus, lifted it up and read the weight off the ruler type scale.

Yes Labrat that’s the gauge I have somewhere, if I could only find it.
And it was a promo give away.
Very handy, but maybe not appreciated by some HiFi buffs.

I use a simple postal balance for adjusting my players. It's very cheap and it reads up to 30 grams in one gram divisions. I loop cotton thread under the headshell, grab the loose end with the balance's clip, and lift the arm just a fraction above the record surface. That way the counter weight spring in the arm pivot doesn't confuse the issue and give a false reading because the arm is too high or low.

I've got it working with the 190mv cartridge, but it might be a dud as one channel drowns out the other, when disconnecting each in turn from

the cartridge the right seems a lot louder than the left and if I swap them around then the left is louder so it seems to be a fault with that

expensive damn cartridge? I adjusted the weight just by turning the screw to the point that the needle starts and tracks without skating

across the record, as it does if too light!
