Well I have to say, ever since I stumbled upon diyaudio.com I have been engrosed with DIY projects. Everyone has been very very helpfull, and very willing to share information! I am planning to be quite busy in my spare time building TL's, and now adding an amplifier to into the mix. A "cudos" goes out to all who work hard in keeping this foram up and running! As well, I would also like to thank all who have helped me along my journey in into the DIY project!
So, getting with my enthusiasim out of the way, I am going to build the Zen Single-Stage Single-Ended Class A amp : > )
Does anyone have any experiance with this amp...just wondering if this is a good amp to be my FIRST...DIY amplifier.
Also is it possible to find PCB's for this amp, or would it be better (old school style) to "hard wire" it?
Can't wait to get started! I'll post many pics of my progression with the TL's and this lovely little amplifier!
Wish me luck...I have fat fingers, and they sometimes touch things they shouldn't...Ouch...that was hot...and live :>)

Yes Sir/Madam, you are correct...Toronto Canada!
Don't know why there is a huge following of DIY'ers in Canada...might be because it's difficult to find great audio gear/parts at a good price? Might just be a lot of people in this erea love to build, and learn all they can on interesting topics...birds of a feather? I wonder if there is some sort of club?
I can't answer why...I just love to do.

It's a great amp for starters. Just be sure you understand the 8ohm requirements and it's slight ineffeciency and heatsink requirements. You can purchase the board from www.audioxpress.com.
Also, there have been variations on this amp on www.passdiy.com. There is a more powerful and more effecient, the Zen Version 4, to be revealed soon. It will have a board that you can order directly from Pass DIY.
Good Luck,
Vince

Hi Rino,
When your brousing the PassDIY site, be sure to checkout the Gallery here:

You can get a lot of ideas and a good feel for what it might take to build the various Pass designs.
But always have fun ah!

Great information! Thanks!
This should be a good starter amp for me. Now I just have to source out the parts.
Question, it calls for 2 Toroid type trans. (one for each channel), would you go for that or source a single large trans. for the job.
As well, could I largen the caps for better power/filter transfer...I like good "Bottom end".

I play with Zen V2.
Good, good, good, bad, good, good, ugly, best.
The good?-- Simple and easy DIY. Easy p2p building if we want...
The good?-- The sound...
The good?-- The output coupling capacitor entirely protects the speaker...
The bad?-- On switching on, a short popping sound from the speaker at the moment of initial charging of the output coupling capacitor...
The good?-- The ¡°popping¡± action kicks dust on the speaker cone off...
The good?-- Easy to fix or upgrade...
The ugly?-- My box calls for a partial make-up...
The best? Many Zen fans can give you very helpful tech tips...
Enjoy!

Hi Rino,
With a Zen, there i$ almo$t no $uch thing a$ too much heat$ink. You ju$t have to $ee that $ometime$ there i$ a limit.$$$
Actually, you don't want to run the FET's too cool, but with the Zen, that shouldn't be a problem because about 80% of the input power is turned into heat.
So stay C@@L
