yep very very good idea AlgirdasR x mono amp

 

[SRMcGee]

Hello everybody,
Posting some images of my recently completed First Watt F5 monoblocks.
It was a fun project. Still need to build speakers to properly test it 🙂

Algirdas:

Nice work! Reminiscent of the original Aleph series amps (albeit from the front only). How do they sound?

Regards,
Scott

They sound clear. There is no obvious technical problems, no humming, no noise.
However I do not have proper speakers at home to properly appreciate these amps (how lame is it!). I am thinking of making Troels Gravesen TQWT speakers to match them. But it will take some time.

I see you have an easy option of pre-heating to speed up the bias adjustment 😛


Nice build!

Harman Kardon Citation 12 Pass Labs DIY power amps

Here' s some pictures of two stereo power amp i did based on PassLabs Citation MOSFET complementary outputs IRF240-9140.
PCB is from member here TAZZZ.
I've had two of those HK Cit12 and i only kept chassis, power transformers.
Did exact as per schematics with some 1% resistors and bourns 15T trimpot for bias.
Both amp do have a relay delay turn-on feature protecting speakers.
Bias at 200mA and offset below 30mV.
Heat sink temp runs about 90F,

Front is solid walnut with blue LED for each B+ and clipping indicator.
I have 60000uF per channel and B+ is +/-40,5 Vdc.
Lots of clean power in 8 and 4 ohms load, great sound


Thanks to Mr. N. Pass !!

very cool, love the walnut

Aleph J. It's wonderful. Really put's some soul in the music. Were elated to say the least. Runs right around 53° C.

 

[Indigent Audio]

Very nice love the heatsinks and inputs on top

Very nice "tube style" cabinet!

Agreed! Love the wooden chassis - walnut? I used some walnut burl on my Aleph-J. Images are in my signature link.
