Zen lite

[chrille]

Anyone build it? What is the effect rating?

i love it for simplicity.

this one may have 4Watt or so?

Do you know what kind of lightbulb Nelson use in his circuit? Brand?

Figure 5 shows the use of a 300 watt Sylvania bulb. We will later be showing performance of 2 such bulbs in parallel for more bias current

from the article

loks like lighbulbs. 300W 115V or so.

i was not able to find what i would need to go this way. No ceramic sockets, not 600W 220V E27 bulbs. I have one 300, one 500 and one 1000W 220V E33 bulb and no socket.

It works with halogen also.

If anyone has a few nice ceramic sockets and bulbs around 1kW for me...

The first one i built was with some 300W halosticks in parallel and had about 10W.

Maybe this could work:

I used some 3x20W 12V in series with my SOZ. I replaced just for fun two 8ohm resistors, and worked just fine!

here is a pic

it's cheapear to use 50W power resistors 😉

chrille,

your link doesn´t work.

If you want to build this ZEN, I think you shouldn´t worry about what kind of bulb. More important is a god ripply free power supply with some effective filtering.

How about the sound of Zen lite amp? Compare to other Zen amps?

I haven't built one, but I'm going to go out on a limb and say that the Zen lite ...

has a knack for illuminating the soundstage!

(sorry. couldn't resist.)

I think I am going to build exactly after Pass circuit of Zen Lite with one 300W bulb per channel. But how many watts can this circuit deliver?
