A Decca London Blue is a great cartridge, and totally unconventional.
The Decca is made of plastic and is enclosed in a pressed aluminum box. The mounting bracket is another piece of plastic that the cartridge clips on to.
They only have 3 connections and they have 3 coils that work in sum and difference mode to create a stereo signal. The cantilever is vertical and retained by a piece of cord. There is no rubber to dry up in a Decca!
The Decca is reputed to have great speed, dynamics, and stereo.
I owned a Decca Blue and a Decca Gold
The Blue was rebuilt by A. J. Van Del Hull in Holland.
The Gold was rebuilt by the Garrott Brothers from Australia.
Both were amazing cartridges the best I ever owned.
Some info on rebuilds here
Decca cartridge rebuild [English]
Been a long time since I last looked at any info for the Decca cartridge.
Suggest you Google 'Decca Gold' for info.
The Blue was a budget version with a spherical tip and tracking weight was 2 - 3g.
Having a blue instead of a gold is of little consequence if it is rebuilt.
