esp project 101

[sierramike]

any body has a schematic with components values for esp project 101
i heard is very musical and extremelly powerfull

thanks

hi sierramike,

You need to buy a board from Rod Elliott to get the proper schematic.

Here's the link:

HI
It is really a great sounding amp .
Yes you have to purchase the pc boards to have access to the real schematic .
The board are good quality and very cheap . Rod will help if you have any question even if these will be your firs project you can be sure you can finnish it .

Regards

Agreed these amps kick butt,Period !! I built two,two channel hi-power version.They sound excellent....Do yourself a favor "buy the boards"

[sierramike]

will do !!!!

finally we will buy the project 101 .......the truth is that i dont need to construct the project ...i only want to compair it with legend 8 and legend 4 me and sakis east_electronics@yahoo.gr working on

project 101 is not quasi like legend but drive should be arround the same ...we both like to investagate that .....

will see....... all ready contact rod elliot and now making shiping arangements

thanks

[Greg Erskine]

Hey sierramike, are you friends with sakis or business partners?

 

[sierramike]

we are friends

and started to construct legend 4 for sakis and legend 8 for me

we run int the same problems ....both

probably dr bora missed that rail voltage was arround 66 volts or sakis or both ..... whatever any way ...this circuit cannot operate as is in this voltage .....

we both now look if there is any chance to make any changes to get this running safelly .....

the truth is that we are constructing amps together ...we have to make about 15 each ......we have to construct in various forms stereo or mono or amplified speakers etch etch

we have to make all this and give almost for free to school for kids with special needs and used in music and multimedia courses for some really talented kids....


we are getting kind of rush now cause a) we are late and b ) we spended a lot of money ( that doesnt belong to us ) in making pcb and mosfets for a project that doesnt work .....

neet eee.....

ESP Project 101 - Lateral MOSFET 2SK1058 + 2 SJ162

any body has a schematic with components values for esp project 101
i heard is very musical and extremelly powerfull
thanks

This is one good mosfet amplifier
No doubt about it

if we have some basic knowledge we can easily figure out components values
we probably have 200-300 persons at this forum that can do this

As this amplifier is very basic with few transistors
is easy to try some different current settings
for the different stages: input - vas -output
and see what works well.
---------------


As can be seen in this schematic Rod Elliott even tells us which transistors he use
2SK1058 and 2SJ162 should be possible to buy almost every country.
They are Lateral MOSFET from Japan.

An externally hosted image should be here but it was not working when we last tested it.

 

[jaycee]

To be honest you could probably guess the part values easy enough, especially if you look at Rod's other amplifiers.

 

[lineup]

yeah, exactly, jaycee

and if we can not do it ourselves,
there are many around here to ask for some realistic values

i could make up a new schematic with good values
but i am kinda lazy for time being:
Because watching Olympic Games in China

[jaycee]

I could, but I won't out of respect for Rod whose site really helped get me started in learning about audio electronics.

is a fantastic audio man
whatever you want to know ... at his site you can find it

Agree gaborbela, really good amp!
I've built both, hi & low power version (with Exicon MOSFETs).

The board are good quality and very cheap.

Cheers,

can anyone plzzz give me the real values of the components of this amp....????

Buy a board from Rod and you will get the info you seek. Otherwise I doubt anyone that has the component values will surrender them. Its kind of a promise we all made to Rod upon the purchase of his boards. The component values are intellectual property of Rod Elliot.

 

[Dr_EM]

The reccomended Exicon MOSFETs don't appear to still be available:

Lateral Mosfet

unless the ECX10N20/EXC10P20 are also suitable? The Hitachi/Renesas devices seem to have dissapeared completely from UK suppliers now.

Perhaps these would be suitable:

ACD100NSD Lateral Mosfets - Class-d Limited
ACD102PSD Lateral Mosfets - Class-d Limited

Not sure how specific the devices need to be in this design.


I've built 3 using the bought PCB. It makes for very easy construction and it certainly is a good amp, great for bass especially

riddickbt: It´s just US$20/pcb...
About the rest from XEAGLEKEEPER post, please see Rods - ESP HP...

Hi Dr. EM,
I've built only two (Mom & baby)...

Yes, it certainly is a very good amp... also very good for mids!

Hey, I might choose to build this amp

reason, I have two monster trafos, 2x 38V/25A
and I have 8 pairs of Renesas, thightly matched
also have 4 big heatsinks
seems all I need to buy is supply caps, and a few components

I would like to build with 4x output pairs
hardwired output stage
and I will ofcourse buy board(schematic and boom)

Any reason not to ?
