Pics of my DoZ amplifier

Hello.

Here are some pics of my DOZ amplifier.
This is one of my first project. it is around one year old.
The total cost for amp was 130$.

Cool amp. Congratulations.

Not bad, not bad at all! Congrats.

Looks very good indeed.

BTW, which PCB did you use ?
The smaller heatsinks are the capacitor multiplier psu, aren't they ?

Please add some infos with the images.
How do like the sound?

ps: I am always "a bit" jealous when I see friends making their first DIY amp and the dammed thing looks so fine, like yours - I made lots of amps in different states and sizes in the last 30-something years and not a single one looks close in any way...

thanks all for coments.

i made PCB boards my own ( not realy big problem)
yes a use capacitor multiplier psu beacouse sounds better in this amp.
but this is a realy low cost project so the capacitators and resistors are not exotic thinks.
some day i will change output transistors with mj15003.
the sound is quite good exept power. but for normal listning is good. in sound quality bits rotel rb981 amp. better space, trebble..

Very nice ....

I'm planning to build a DoZ sometime in the near future. What sort of chassis and heatsinks are they? Did you make them yourself or play around with off the shelf components?


Very nice indeed ....

Beautiful! If you didn't say it, I won't believe this is your first project! Good work! What type of chassis that you used?

 

[janey]

the chassis i made myself and use one 30x20x4cm heatsink per
chanel. the amp disaptes around 160w and runs quite hot.

That is one fantasic amp! Dont suppose u live in melbourne and are looking to sell?

Hi Janey,

What transistors are you using for the capacitance multiplier? I see one T0-3 transistor, are you using a pair? I'm curious as to how many you have and what kind of heatsinking you're using for the multiplier.

Regards

Hello
You can share PCB file DoZ. Thank you.

Look at the account and date..!

Elliott Sound may have premade DOZ pcb
