The conventional fuses supplied were of ordinary quality and the nickel-plated brass end-caps tarnished with time.
This causes an increase in electric resistance and may hinder the flow of power to the CDP's transport and PCBs.
To solve this problem, the fuses were replaced with 24K gold-plated end-cap Bussmann fuses (~ 4 British pounds each).
The pictures below illustrates the replacement of the fuses.
Bussmann fuses can be ordered from www.bussmann.com (England).
