SMD Aleph Mini's

[jleaman]

Ok i got the boards arrived from briangt. Id have to say that these little parts are a time consumer .. Ill post pics in a day or so guys. I'm not rushing this at all. They do look really nice. the best part about these is that they are gold plated. The solder sticks really fast and easy when soldering smd parts. Well done brian.

sounds fine I´m in no hurry,take it easy.

I am after a set of boards as well. I emailed BrianGT about getting some of a small run he mentioned in the other mini a thread. Just wondering if these are the same ones.
Either way I would like a set and a group buy as well if there is one.

Mark.

These are the same boards. I haven't actively sold these yet, as I did a small run, and will order more after the first batch of amps has been built.

I'll do lots more soldering tonight see if i can finish these proto-types. Then post picture's. I have to warn people. These resistors are SO small.

Ok guy's here you go. Smd Mini Aleph's.

Nice,I´ve been soldering some smd buffer´s,yes they are smaaal.

Could we have an idea of the cost of these kits?

Thanks

At this point i Dont really know BUT i can say this. It is not going to be expencive..


I have to talk to brian still. And see

 

[jleaman]

OK, so after waiting 7 weeks to get 10 resistors ( smd ) from Mouser they finally arrive and well look at this. it took me a total of 10min to solder them all in the smd mini a's are complete now to get them up and running.

Any one want to see pics ?

 

[kozak]

off course we want to see pics!!!! and we want audio results also!!

 

[jleaman]

Ok no audio results yet but i can say this the last SMD batch was better then through hole. Those got given back to Brian. BUT these ones will sound really nice as i bought all nice dale resistors too pics ill post

Here we go Just taken

An externally hosted image should be here but it was not working when we last tested it.

very nice pics. Why didn't you fixed the heatsinks on the bridge diodes?

They wont need it. If they do ll create some small ones..

 

[jleaman]

So i just did a test how to clean boards. THIS IS easy.. So the first step is to buy some Flux remover created buy MG chemicals. So the fist thing you do is spray the board with this stuff then scrub it clean with the tooth brush. After that rinse clean with hot-water then spray with cold can of air. to move all the water off fast.. i just did a board and they look really really clean.. I have yet to find any thing else that works well. I was told i could rubbing alcohol instead of water..


Pictures to come if any one interested.

A update of this soon will be mounting these to a heat sink and getting them fired up and running. I am hoping no problems. I cant see any problems arising from these but..


The configuration will be..

4 channels 2 x 2 stereo blocks. each channel will have it's own separate PSU board and transformer.

I have used alcohol,on the boards that is and after flush with water.

Pictures to come if any one interested.

Please..
