My Dream Aleph 2 Coming True

[nrg2009]

I will upload the schematic tomorrow, hopefully that will help.
A question on tapping screw holes. Could you provide feedback on a decent set? I found this set that looks interesting.

Thanks..

Thanks..

Schematic: cool thanks.

Tap set: I've never used one like that. My first thought is this type is proably for sheetmetal. But I have no other info to say that but my gut.maybe someone here knows better on those than I.
On tap and die sets: if you plan on more diy amps, I would sujest a good tap set. Greenley is a good brand. Do yourself a favor and don't cheap out on taps. I have a set that was my grandfathers. It was allot of $ in that day but 3 generations later....
If your not planing on allot more diy... Go to ace hardware and get the 2 or 3 you need.

Just my 2c some might say I over charge.

hi all,

My tube amp got blown away now looking to buy an amp then got this Aleph amp DIY..
may i ask some question being a newbie...

1: how much cost it takes to build this DIY amp with good quality components

2: how much time does it take

3: how difficult it is to build last time i soldered something was 13 years ago in engg days

4: how this compares to name brand like Classe,bryston etc...

sorry for newbie questions..

1. I don't know I did a diffrent aleph.
2. I took 3 months for aleph 1.2
3. Not hard. But be prepaired do some reading and you will be fine
4. Diffrent. But if you like tubes aleph is a good match 4 you.
Classe and bryston are good amps. But diff circuts. I like older classe amps but not as much as aleph. I like bryston too but for brute force.

What kinda speakers?
What tube amp died? Did you like it?

Thanks for replying...

the tube was Yaqin ms-34d ....i like Solid state amp sometime i cant even tell the difference...

btw how much was the cost...

i am currently running full range gerhsman acoustic speactor down the line i am planning to make DIY mini statements or DTQWT mkII ...not sure yet...

Here is the schematic.. The quality is very poor. I will try to re-do it as soon as I get a chance.. I hope is is workable for now..

I can roughly answer the cost, it's not inexpensive. I did not track the cost closely (on purpose! ) and things such as tools, wire, solder, etc that I bought are not in this equation. I bought nice components, such as wirewound resistors, etc.

Rough estimates:

enclosure/heatsinks $300
components $225
Caps for power supply $100
boards (kk-pcb.com) $ 150
Torroid (Antek 35V - 1000VA) $215
Matched FET's (240/9610 from Tech-diy.com) $130
Lots of patience and persistence $priceless (I couldn't resist that tacky joke)

I hope that helps. It's a fun project to do. Your soldering skills won't be an issue, I never soldered before this project and know I even know how to de-solder as well.

thanks for reply..so give and take you are out 1500$ for this Class A amp...and hope the squueze is worth the juice...

my cost was around 2500$

There is a better copy of the schematic at http://www.kk-pcb.com/aleph-2.html

BTW the kk-pcb PCBs don't get very good press.
