Pictures of your diy Pass amplifier

Very nice!

Aren't those heatsinks intended for air forced kooling?

actiually, I think they are optimal convection type

Never tried but enourmous dissipation capability with silent squirrel's cage fans.

This is my Aleph 2, finished in summer 2009 after a 5-year build.

Thanks Nelson! They sound great!

Wow; such skill!!

Never tried but enourmous dissipation capability with silent squirrel's cage fans.

This is the thermal resistance of the heatsink for 5 m/s (!) airflow: 0.035 K/W.
With 1 m/s airflow, which is more realistic to tolerate in a living room situation I would expect 0.07 K/W

Thats got to go in PassDIY hall of fame!

That is some fine skill!
I am so jellous

Heat issue too.
Of course the bass amp have to meet the requirements, but classA is a waste of money and energy.
Just my opinion.

So you confirm that it is, in fact, just an economy issue.

Congratulations Bill, your's is one of the most sexy F5 amps that has appeared around here...IMHO

Maybe on the F5 it works better for it to be in Class-a, from experience with other amplifiers, this is not the case and full class-a tend not to have the life exhibited by a good a/ab amplifier. class-A can be smooth, but dead by comparison.

Now it is really finish. The first amp the even my wife can use

(well, it is solidly connected to a DAC with output caps and delay circuit, so no issues, at least on the input)

I think I will drill some holes in the shape of F5 on the top for ventilation. Now is kind of sealed, although the temperature inside is around 50 C.

I also think I will have to put a bumper on the edges, if I do not want my son to have the heatsink imprinted in his forehead sooner or later (But this would be temporary)

Nice and simple. Good looking build Nikon.

Can we see pics of the insides (with more amp and less carpet)?

Yes, but shot with a Canon

so ...... that's why I don't see red eyes ......

 

[jacco vermeulen]

To some, it's comforting when the price tag of the camera is far less than the object it images.

(suppose every individual on this club would post pics with a 1DS or D3S body label => PiyAudio. )

 

[Nikon1975]

You can see the inside in post 463, when the back and the top were still missing.

I have a small Canon and a BIG Nikon. If I need a 100 kb jpg I don't use the BIG one

Funny that I had the same reaction when I posted the pictures in the Tubelab forum.

This is the my B1. OK is temporary, but it has his own style.

Do you find that enclosure gives an all natural, young and fresh sound to the preamp?

All kidding aside, it's always good to see a working project!
