Need to build simple MOSFET preamp!!Please help!

[thomgun_lc]

Hi guys. I want to build an active preamp with a MOSFET. But, i often found very complicated schematic.
Does anyone have a simple MOSFET preamp schematic??
This preamp only have about 2x gain. I use it for line level preamplifier.
Need ur help.

google for "bride of zen"

As far as i know "bride of zen" is power amplifier not line level preamplifier.Does anyone know another simple MOSFET preamp schematic?

Hi, did u try to google for it and actually study the article?
the title of the article read as this:

The Bride of Zen: A Single Gain Stage Preamplifier


i actually built according to the schematic and use it as a preamp..this is as far as i know too. try googling, it really helps.

wow,can i add a 6922 tube as a buffer before "BOZ"?

but why would u need a tube buffer before the BOZ?

Hi,
You asked about a Mosfet preamp, now you are talking hydrid. What's up?

It was too simple

I forget to say-google for BOZ,and use simpler supply

now you don't need to type google

Why simple ? Again 101 way to miracle ?

CAn i substitute IRF610 with another MOSFET?? BEcause i'm difficult to get that IRF610

sure you can.

Erno Borberly (developer of the Hafler DH101 preamp) keeps an archive of the articles he wrote for AudioXpress --

http://www.borbelyaudio.com/special_articles.asp

some of the circuit boards are available from AudioXpress.

before u ask 'so what other mosfets can be used?' , have u actually read the BOZ article yet?

same piece of advice -- do yourself some good, google for the Nelson Pass article on BOZ. the answers are all in there.

What is the substitute of IRF610?IRF510??I'm looking for IRF 610 but i only found IRF9610. Maybe there is another IRF610 series which have same characteristic.
What's the diferent?
I'm sorry, i'm newbie in solid state amp.Actually i want to build a Preamp to accompany my Gainclone.
I found that bride of zen is a good and simple preamp which provide a little gain Maybe, it's suitable for my Gainclone amp.
I'm not satisfied with a passive preamp, i need to give a some colour to my gainclone amp.

I need to make my gainclone amp become more dynamic by provide some level line.

there are tons of substitutes for the irf devices. just look at an irf databook. most of them are mosfets, tho.

 

[thomgun_lc]

Thx for ur information. I have some question.Does the headphone amp can use as preamp?
Does anyone know about site which provide some transistor(mosfet) listing?So, i can know the subtitute for irf610.
Thank You

Yesterday i found this schematic, but this is poor scan, it's called mjamp.it's a simple amplifier does anyone have the good schematic.

I think this is a good mosfet amp and simple amp.

 

[thomgun_lc]

Does anyone try this AMP?I think this is a very good amp.Take a look at the picture.
