On diyaudio.com some of us are working on an updated version of the super leach amp....

It is based on the leach layout that blackmtx mentioned

'

Considering that I have made the layout avalible for free, please don't just copy it, make your own and make an even better one that fits what you want the amp to be like.

Hi Jens, welcome to Pinoy DVD!!!

I've got 2 pieces of your leach amp pcb courtesy of Sir Tony and still waiting for other parts to arrive.

Jens, for your info here is my PCB layout, notice that my pcb layout is only single sided...and I used 8 TO-3 power transistors.

and of course, I did not copy your layout.

what is the board size? btw, i am in russia as of now, will be in manila by third week of july.

Hi sir tony, surely, pagdating nyo marami kayo pambili ng eletronics parts

.The board measures 4" x 7.30", I'll be using MJ21193/MJ21194(TO-3), -/+70V power supply and conrad double flanged heatsinks(MF20-2F-151.5)

Does anyone here know of a good vocational school to learn electronics specifically for Audio applications?
i would like to pursue my passion for electronics.

i know this is out of topic. but it seems that people on this thread are knowledgeable on the subject.

any help would be appreciated.

Thanks

I do not know of any school for Audio applications. However, should Audio electronics be of interest to you the first start would be to enroll yourself in tv/radio repair technician course. After that you can start reading up on applications of the various components used

eg Capacitors, Resistors, Transistors, MOSFET and Diodes

Since there are various types of the above components it is best to understand their applications. You can do this by scouring the net on the manufacturers website. They typically have application notes.

Still not satisfied ... you can enroll yourself at UP Diliman in their power engineering courses. Here you will get to learn about switched mode power supplies. More importantly, the potential application of above components are mostly applicable for Audio electronics. To get your spirits up, fact is a good number of people who have worked in Audio electronics feel at home with switched mode power supplies. You get to learn about phase margin (why this is very important for amp stability), feedback, EMI, transformers etc etc which you can then relate to Audio electronics.

Thanks Rascal101.

Are the courses you reccommended vocational?

rascal101 · « **Reply #68 on:** Mar 16, 2006 at 09:56 AM »

The power electronics course in UP is about 1 year. You have to call them though to check. PM me if you are serious about this.

To all:

Just realized ... pls contact our trunkline 995-4000 and ask for Roy Closa about the power elec program. Siya nga pala iyung resource person for this. Sorry for the previous PMs, info sent ...
