What Pass designs have you built?

[jackinnj]

F3, F4, F5 and Impasse

 

[fff0]

It sure did!! After all these experiments with Nelson's designs, I always find myself gravitating back to Zen.

Which Zen variation are you referring to particular?

Which Zen variation are you referring to particular?

We are referring to the original Zen, or at least variations of it.

A40, and a MOSFET A40, Zen, Zen Revisited, SOZ, Penultimate Zen, ZV5

In the works: ZV8, F5

I like 'em all, but lately I've been nostalgic for the orginal. Maybe I'll try to build a really big one.

My Pass Projects

Hi,

Here is my list.

A75
Zen
SOZ
Aleph 30
F5

The Aleph 30 became the F5 and I’m considering changing the A75 into a BA2.

Lots of fun!

Bride of Zen (with off-board regulated PS) and B-1.
I have most of the parts, except the heatsinks) collected for a Zen-lite amp. Got inspired by Nelson's amp-on-a-board at BAF and started rummaging for parts this week. Was hoping to build it completely out of stuff at hand, but I don't have any big heatsinks lying around. Anybody tried bolting transistors to an old car radiator?

A40
2 x F4
Pumpkin/Shunty (ZenMod creation, but in Pass Labs forum)
F5
Aleph J
2 x AlephJ-X in progress, but one of these days

Never have enough of them. More building = more fun ...

Thanks again Nelson and many others who help.

completed: 2x B1 buffers
In progress: F5 (still looking for a case / heatsink combo)

looking at: one of the zen preamps...

Let´s see..:

2 pairs of Mini-A monoblocks
1 ZV9/F3
1 ZV7 (resistor version)
+ several "own" designs with obvious influences from Nelsons work such as
Baby Zens, Baby ZV4 and various unbalanced resistor- and choke loaded Mosfet amps.

So, which amp for which speakers, sounds best to you?

Busy beaver! We should hook up sometimes.

That has been over a number of years. If I recall correctly the A40, which was my first taste of Pure class A , was built in 1988-1989 time frame.

If you ever put on a DIY meet in the Portland Oregon area I would like to attend. If I was invited.

[Ryssen]

I´ve built:
F3
F5
Soon the B1

Not meny compared to others...

Well, I originally started out to build a pair of Aleph 1.2's but somewhere along the way they transformed in Aleph-X's. Now if I could just get my second monoblock to work ....


This forum has always been a great inspiration to me. It's a rare situation that one can communicate directly with the original designer and knowledgeble enthusiasts.

Anyway, it's been great fun. It started out as a father-son project but unfortunately it's up to me now.....
