Meridian Unplugged - Powered by MrTechGuy.co.uk Forums Thread Like Summary - DSP life expectancy

We're moving to Italy when we manage to sell our place here. My 5500s are pretty old Mk1s; I'm guessing they must be 15+ years old. I've never had any issues with them and they still look like new, but how long might I reasonably expect them to last?
They typically get about 30 hours use each week and are usually run with volumes between high 50s and mid 80s.
The reason for asking is that if anything major went wrong with them then shipping them back & forth would presumably make it uneconomic, even though there is a dealer in Italy.
There was a recent thread about 200 CD transports and most appear to have died. I'd expect speakers to outlive CD players, but does anyone have a take on average life expectancy?

We've done about 10 out of 15 speakers so far. Took 10 days before they even shipped the part out.

If your speakers are 24/96 with older 7 Segment Display I can almost guarantee your resistor is toast and the board damaged.

Some Matrix Display units (later ones) have the 330 Ohm 4 Watt and some don't (earlier ones). 4 of mine had the 330 Ohm 4 watt and looked perfect and 4 looked just like the 7 segment display models (i.e. toasted).

Every one with "brown" resistor had damage to the board. And getting the toast ones out was not easy with out further damage, due to warping and swelling of the board in that area.

The two 18 bit I have left also looked good, but that was a small sample.

Out with the old in with the new.



I mounted them a bit above the board so as not to use the board as a "heat sink" any more.



Nice looking factory fit.



All of them needed rework like this. Some needed rework on both.
