Default AEM 6000 ready to build

Hello everybody,

my bunch of PCBs arrived from PCBWay, and i am strarting now to build up the amplifiers. Thanks again for that wonderful design to Suzy Jackson.

So, what are the hints and tricks to make this beautiful amps successfully work.All parts (Melfs, capacitors, SMD transistors, driver and powe transistors are already available. The pcbs are double layers with 2 oz (70µ) copper. As far as i know, Suzy uses 3 oz PCBs.

Any comments to that project???

Best regards

Gunni

Default 1st picture of unequipped board

hi,

this is the first shot from front and backside of the unequipped AEM-6000 boards.

i 'm really interested how this amps will perform.

Buna seara Alexandru,

nice to get with you in contact here. i read a lot about your designs and brilliant work here. It's a real pleasure to get with you in contact.

As i saw on the picture, you built already this amplifier. What's your experience with that nice amp.How do you estimate the quality of that design. Are there any tricks (Parts, type of parts. changes in equipment) to get the maximum quality out of that design.

My plan is a dual mono design with about 2x40 AC toroid transformers.

Multumim si la revedere

Günther

Hi Gunther ,
What can I say , thanks for those kind words addressed to me , and about the boards ,they are with dust right now . They was never functional (lake of time ) ,maybe in the future. I think they will perform nice ,without any problems .
You must pay attention to rectifier bridge to be selected correctly ,something like 36A and voltage over 100V or so and heat sink for drivers and final transistors.
I wish you success .
Regards ,Alex

And what about the input transistor? Anybody knows a substitute for this transistor, reading the datasheet this transistor was discontinued. Any store dont have this transistor in stock, and i really would like to make one of this fantastic amplifier. Please help me!

Hi fannatic,

sorry for the late answer. If you talk about the Fet input transistors, i can send you a positve reply, They are still available as SST404 from Calogic.
https://www.google.de/url?sa=t&rct=j...IK4VY4QZx7rWDA.

i got them here in Germany for about €8 per piece.

Best regards
Günni

Sorry for the late answer to. I bought an equivalent transistor of the sst404. I found the original project transistor. I hope this model works fine in the Suzy modificated project. the number is ECG461/EXR461/2N5546 the price was so good.
US $ 6.95 per unit plus the transport.
the transport to Brazil was so complicated and expensive. Just the shipment was US $9.70

Thanks for your assistence!

hello my friends, i'm now ready to assemble my own AEM6000, but in the schematic exist 2 trimpots and no reference about how it`s adjusted.
Anyone have any idea about the parameter to adjust this trimpots?

In the original schematic, i found the adjust of the second trimpos, it`s the most close to the output MOSFETs, but anything about the input trimpot. Even so, that value would only be useful if I were building it based on the original scheme, and I'm following the Suzy Jackson project.

Anybody can help me?


Thanks in advance.
