True, but in the end i understand the question being that he dosnt want to spend un-nessecery money, not that he dont want the best possible....maybe im wrong.

In the end of the day its terribly expensive to upgrade half of the amp by buying better parts (that could have been bought in the first place) within the first 2 weeks.

Default Where can find these parts?

I can not find the thermostatic switch rated at 75 degrees C used in Aleph 2 and 5 in either Digi-key or Mouser! Does anyone has the part number to order?

Also, I like to use the copper plate to connect the large filter cap. Local Home Improvement store does not have it. Anyone knows where I can find them (in US)? (like a 2mm thickness used in the photo)

Thanks

Thomas

The point i'm trying to make is you do not need to build
an Aleph 2 with exotic and expensive parts for it to sound good.

The Aleph series was Class A pretty much across the board - no
matter who was reviewing.

My Aleph 2 sounds great and compares nicely to my production Aleph 3...
sans exotic parts.

First time builders shouldn't be lead to believe that their amp
will be second rate if they don't use exotic parts. And where's the
fun of experimenting if you use exotics right off the bat? You have
nothing to compare to. Someone certainly isn't going to take out
Black Gates to see if it sounds better with Panasonics!

(sorry if i'm going on and on)

Tomchaoda,

Look at DigiKey : #317-1000-ND

Thermostat 70 C NC with leads

I will use two to protect the final stages
of my A75 and cut the power supply in case of overheat...

Alain.

Default Parts found!



Thanks for all info regarding parts question I posted earlier. I also find them and would like to share with you.

For the 75C Thermostatic switch, I find one I like in Digi-Key.

Digi-Key: #317-1001-ND

Mouser has Vishay Thermal switch rated at 70C or 80C, but not 75C. However, they do not have them in stock!

For the copper flat sheet:
for 1 mm (~0.04"), they have it in Thompson Emanel, link here:
http://www.thompsonenamel.com/produc...rflatsheet.htm

For 2 mm (~0.09"), I found it on eBay, but it is not cheap! But I like 2 mm for better conductance.

FYI

Thomas

You should rather use 2 * 1mm than 2mm for better conductance....wich is though irrellevant in this case, since 1mm * 25mm copper bar is more than overkill already

This is actually the best solution...Ive used flexibar in many applications. A very fine product for rails and or grounding.
