The right channel output unexpectedly and suddenly “fatally went” on my REGA ISIS VALVE cdp/DAC.
- It was a “failed” output tube …. yes, ….BUT….
- it was also a bit more than just an isolated tube alone BECAUSE of of further damage from that failed tube,
Kindly let me explain .
- I i took it in to a pro tech to scope it out. YES …. it was a single sudden failure of an output tube …. BUT ….that failed tube somehow also created a power surge overload that also fried some resistors and ? (I’m no techie …) on the main board.
- It required a pro tech added repairs for about $600 + the added discretionary costs of a new full set of quality tubes.
- Under his recommendation to replace them all together in a high-end unit after a nine year run from new, ….All four tubes were also upgraded to a matched set of brand NOS MULLARDs.
(who knew?) . But that was another further discretionary added $600 (ChaChing! …but well worth it in an improved audio performance. .
TAKEAWAY:
(1);May I suggest that you have a pro tech check it over first instead of casually assuming it’s “just the tube”, it is a very cheap but potentially important cost of insurance.
(2) All tubes are NOT created equal.
