What happened to the nice guy from BAA? He used to build one amp per day. Nothing happens anymore. Does somebody know something?

This website is new for me, Thanks for this link.
I don't see any schematics, are they available somewhere?

 

[Vrystaat]

He is a very nice and helpful guy, if you register then all the schematics are available.😉

 

[amplidude]

I'm registered but can't access schematics, and would really like project 41

What do you need?

What do you need?

Hi,

I sent you an email a week ago or so...but no answer. So I'll take the opportunity and repeat the request here...I need a bom for the project 63 (in the email sent I elaborated what I'm doing right now and why I need a boom for Project 63), thank you!

 

[BAAzar]

Sorry but I did not receive any email request from you. Send a request at
projects@buildaudioamps.com and I'll send it to you asap.

 

[aparatusonitus]

Hi,

I re-sent the mail again, also via forum pm if it does not pass thru...thank you!

 

[BAAzar]

BOM sent, Thanks

 

[jlind54]

I'm also interested in the BOM for Project 63. Not sure if my email reached you or not.

Proj63 BOM

Just sent Proj63 BOM, Thanks.

 

[jlind54]

Received, thank you much!

 

[90scaraudio]

Any chance that I could get Proj63 BOM?

 

[UltimateX86]

hello, have you made progress on the projects based on LTC6090 and ADA4700-1 ?

thanks

What do you need?

Are you still building amps?

How is the "upcoming project" coming along?

"This is another audio power amplifier project in the series that uses an op-amp in the input stage. The prototype is populated with eight 800V/20A/200W NPN power transistors from Fairchild Semiconductor configured in a quasi-complementary output stage topology. These T0-264 packaged power transistors are typically intended in high-voltage color display horizontal deflection circuit applications but performed very well in this project. Initial test results shows that the amplifier is capable of producing a power output of more than 300 watts into an 8Ω load with ±72VDC power supply rails."

Proj63 BOM

Just sent Proj63 BOM, Thanks.

By chance, could you resend a project 63 BOM to me

 

[BAAzar]

Just sent your request.

I'm still here and more laid-back with each passing day.

@BAAzar

This one is part 4 with the Exicon Lateral Mosfets,

Part 4 LTC6090 or ADA4700 with ECX10N20 & ECX10P20 High-Fidelity Power Amp.

I have been wanting to build an amplifier with the Exicon Lateral Mosfets, how many parts to you expect to be in this series?

Are you building up towards a "final" version?

These ones are not on your web site, will you be adding them? Or have you stopped listing your builds?

Thank you,

David.

OK, thought I was having a stroke....
What gives on the MJE340/MJE350 semi's? The pinout is E-C-B
https://www.mouser.com/datasheet/2/389/mje340-1849868.pdf
Q5 and Q6 are correct on the heatsink but Q1,2,3,4 don't line up when looking at the PCB and how they would normally bolt to the heatsink...
The way these are bolted to the heatsinks that I can see would have to be B-C-E unless they are bolted with the plastic side to the heatsink.
HELP
Thanks all
