Does anyone have an educated idea as to the life expectancy of the big class-A Gryphon amplifiers? How old are they before caps and relays start to become an issue?

I am no techie, and there are far more educated and professionally experienced people who can answer that. My first Gryphon was 2nd hand and 14 years old when i got it...perfect for about 1 year...15 years old...and then I had the whole thing re-capped, and somebody did not get one of the resistor soldering things right, and after they found it and fixed it (took forever to find), it was great and was told the unit could run another 10 years minimum given that the main thing that gets old are the capacitors.

I then got a 2nd hand Gryphon Colosseum which was 1 year old when I got it, and I sold it after about 6-7 years in perfect condition. I now own a 2nd hand, 1-owner Gryphon Mephisto which is about 4 years old.

Thanks LL21! I know they are built like a tank and with excellent internal parts and quality. Like you have done, I am hoping to climb the ladder through pre-owned purchases so having an understanding of what to expect is helpful.

I know audiophiles don’t like them but you could place noctua fans on those Gryphon amps and they will last a lot longer

say an average audio capacitor is rated to last 2000 hours at 85 degrees

for every 10 degrees you lower the ambient temperature around the cap you can double its life span

and once a year I pull my gear apart and blow off any dust with a small compressor F2365230-68F9-479D-8758-6395CBF1568B.jpeg C75848B6-809C-4FF6-B67F-47224E735DB0.jpeg

there once was an American firm who made excellent caps

these Mallory caps still works and measure well after 75 years

Interesting...How quiet are these fans?

1 fan is rated at 22.5 decibels running at full speed 2000 rpm against no resistance

of course if placed blowing into vents , the resistance causes noise levels to rise

for something Class A like Gryphon I don’t think 1 fan would suffice

my denon POA-a1hdca pictured above I use 6 because denon crammed a tonne of boards into a smallish chassis so heat tends to accumulate . Their preamp was pure class A and even worse for heat build up

12 years and running that denon .

but it’s 46 decibels from my listening position With 6 fans and I have them blowing air into the amp. Its quiteter if you have the fans sucking hot air out

for movie watching I don’t hear them as most of my movies are easily over 60 decibels

I use noctua fans on my Luxman CD player and Vitus Audio preamp ( class a pre ) And vitus power

Thanks. I am working with a manufacturer on a custom equipment rack for the Gryphon, and with glass doors to close off the front to keep from small prying fingers...we were not only going to create a large volume of space with ventilation louvers...but also 2 fans to extract heat from the rear of the cabinet (which will be entirely open as well...no back).

I’m also working on a custom cabinet design for my Essence setup. It’ll have an open front, but need to create some airflow. Fortunately the Essence is reasonable for a Class A amp so I should be able to cool it silently with a couple Noctua fans and some acoustic baffling.

Interesting. Had not thought about acoustic baffling...mainly because so much of the cabinet (back plus side louvers) will be open. Certainly am investigating the quietest fans...and also making sure we can turn them on/off easily. We also intend to have the 'ceiling' in the cabinet sloped so that rising heat is naturally drawn upward and OUT towards the back.

All my new Gryphon purchases have been exceedingly reliable.
I purchased M100 monoblocks around 1996 and they worked flawlessly for 17 years before needing a modest repair.
A friend still has them and they continue to perform reliably in his system.
