Some of the old designs were built to last forever.
Dyanco
Allen Organ amps
I see Macintosh has some votes as extremely reliable.
As someone mentioned, some cities are slim for locating good repair shops.
So this is why I brought up this topic.
If a city has only 1 shop, the tech , if not so fair, knows he's the only kid on the block and can charge whatever he wishes.
Someone also mentioned tube reliability is extremely important to keep repairs at a bare minimum.
Which is why my tech guy, made clear , only buy tubes with very high reputation, and from a shop that has excellent matching test equipment.
He tends to prefer the russian tubes, as best selection.
I note china has new labs , such as Psvane , a lab known to reject any tube that does not meet their highest specs.
But for me, having a 12 tube amp, its too pricey.
I have the gut feeling the Defy7, will be such a relaible amp. This confidence allows me to relax and enjoy the music with no fear of hiss and hum.
The Defy had 20+ yrs, and tech found only 1 issue, the main cable(8 wires) from power trans to speaker out post, was corroded at 1 solder connection, and so we replaced with Navships Silver high tech 12 gague.
Have all new Mundorf caps, and most resistors changed to Takman Rey metal.
