Hi Variac,

This is a great idea although it's going to take a lot of effort for people to recall and/or root out those core threads. Finding the really seminal posts will be an even greater challenge.

Two threads that I believe are really important are "The Aleph-X" and "UGS adventures". I would also go through the site and pick out Nelson Pass threads that present new DIY projects such as the Zens.

Cheers,
Graeme

Thanks,

The idea is that the members such as yourself will post links to the threads they mention. If you could dpost the links I would appreciate it. The mods are to busy to do the initial work so the hope is that the members will come through here.

Where to buy Pass Labs PCB's?

Cannot make your own pcb's?

There are plenty available, and best option is to check the group buy forum or ask here if there is not one running. When looking at other sources, there are some patent issues to bear in mind. Read here, here, here and here.

The links to the articles of the Easy Pieces are not working anymore. Can somebody put this on diyaudio or an other mirror site. At that time I was building the Aleph-X, but it seems like these are nice (cheaper) projects.

 

[korben69]

Yes, broken link to the 7 Easy Pieces...

 

[stefanobilliani]

Guess that is becouse the Passlabs site has been hacked some days ago and also papa's folder is not explorable anymore

 

[Nelson Pass]

You can search for it on DIY Audio.

Amp advice

Hi every One,

Til this day I have been building tube amps.
I am now thinking to build a Pass Amp delivering clean 50-100W (75W perfect) into 4 ohms. Class A. Or maybe a 845 PP tube amp. Decisions, decisions.

My Magnepans (MG12QR) highlight the power limitation of my 15W Williamson. And I plan the purchase of a pair of MG3.6.

Which model would you recommend? Aleph-X or Aleph 5 (60W)? Of course, the amp has to have that sweet tube sound 😀 What else?

Thanks for your advice.

Serge
