I think the UK distributor changed over a year ago. In terms of reliability, I think it’s unlikely that the amplifier would need a service for 10+ years at least. Mine is nearly 5 years old (the warranty is for 5 years) used on a daily basis with no problems whatsoever, and I’ve not heard of any issues elsewhere except occasionally for DC generated hum which is not a problem with the amplifier but mains supply - many makes of amplifier are prone to this and usually can be corrected with a DC blocker.The distributer for Norma in UK seems to keep on changing. Will Norma be represented in the future in UK? Reason I ask is if I bought a eg Norma 140B amp and something was an issue in a one or two years what is the position as to customer support.?
