@lewm @bimasta the Victor headshell is nothing special, just standard. What they call "Chucking Lock Headplug" is also standard SME type.
When i’m talking about counterweight sag i mean defective samples with 20 or even 45 degree sag down of the counterweight and this is not normal (my advice to stay away from them), look at my arm and see what was the idea when this arm was designed, this is the best sample i have ever seen (unused). The counterweight on my long UA-7082 is the same. So when you have a perfect samples on hands you realize what is good and bad (compared to defective samples). The problem with defective samples became obvious with heavy MC cartridges, in this case the original victor subweight must be screwed to the armtube on the back, to balance such cartridges the counterweight position is not close to the armshaft and if the rubber part is weak then it's a disaster!
