GST801 as mentioned is a fine piece. I think I may have the original tonearm lift, and that is the weak point in this, which is not a big deal.
Lustre made 2 different versions of the armlift mechanism for GST-801 model, they are completely different from each other.
The original headshell is not that light mass wise. Without wires and hardware is 9.2 grams.
The exact weight of this Lustre headshell with original silver wires is 10.6g right now on my digital scale. The weight of the screws depends on its length. Two medium size screws are 0.7g. So the total weight of the Lustre shell with leadwires and mounting screws with nuts is about 11.3g and this is still a lightweight for a headshell. I've seen very few headshells with a mass less than 10g (and i have so many different headshells).
