Kofi Annan in: "Seven-Pound Mono Amp"

[Kofi Annan]

Finalized a seven-pound mono amplifier yesterday. Loud, LOUD L O U D sound for a mono amp and no distotion whatsoever. Its very small-- fits in the crook of your arm-- but it does get awfully hot.

Any advice on further modifications to get the gain down would be much appreciated. Just can't seem to turn it down low eneough to avoid ear-splitting volume levels.

See for yourself:

There's something of a squawk in the upper midrange.

Heartiest congratulations! If it's your first, I can break the news to you: the days of sleep are over.

Congratulations to a great piece of work!
Hope you had plenty of fun "building" it!😀

yup definitely not (yet) a DIY project.

be advised however, that the unit's power consumption will increase over time - and if you think it's loud now, wait until it's fully broken in (18-30months)

congrats

congrats!

you'll certainly get used to loudness and efficiency of this class.......

Congratulations!

So how long before you go for the 7.1 surround sound experience? 🙂

Just be glad you only 'built' a mono-block.

If you ended up with a stereo unit, there would be even more cross-talk to contend with.

Congrats, buddy. Fatherhood is a wonderful thing: be faithful to it.

I expect the damping factor needs to be corrected several times
a day.

Congrats Kofi.

When are you planning to expose to soldering gun... and i guess in 15-18 months you'll need a new Mac so the younin' will have their own.

My wife and I have been eyeing those in the shop for a while, they just seem sooo expensive... Not to mention that they sound totaly incoherent during the first year of burn-in.

Congrats, am truely jealous.

May she follow dad's footsteps into little glowy glass things 😀

 

[Gluca]

OH! what interconnect cables are you planning to use?

Lets be glad the little monoblock doesn't look more like daddy.

This little cute Do-It-Yourselves amp has the biggest WAF (Wife Acceptance Factor), yet you must be careful - a lot of microphonics, self-oscillating and self exciting. And you will have hard times to find mute switch. Mine is 18 months and I find the location of the switch changing every day. And beware - no tools!

Congratulations!!!

You have 13 years to live. At that point (or close to it) life as you know it will cease to exist. You will be instructed on the limits of your ability to control your new one's world (and by extension, yours). You will survive (probably) - if you can adapt to this new reality.

It will all come around again, maybe 5-8 years later. Of course, you will be permanently altered by this process. You can't fight it big daddy, enjoy it.
