Tino96,

You requested a deisgn based on Anthony Holton's Lateral FET amp. Here is my take at it. I used his design as a starting point and then went a little further. This is an amplifier for a bass guitar and will be powered from +/- 60V rails. I use IRFP240/9240 devices in this. I will be finishing up with the PCB design within the next 2 weeks. Depending on the reaction, I may post the gerbers for the PCB.

Matto5,

Check the previous thread for my link to the updated schematic on Anthony Holton's site for the 400W symmetrical amp. He suggests the modifications if you are going to use the IRFP240/9240 pairs.

in the thread: 200 Watt Lateral Mosfet Amplifier and irfp240/9240 (segue)

you've attached the bass amp.zip file
the reactions are good?
if yes, I'm wait for your PCB

Hello tino96,

Sorry for the delayed response. I have been busy building a workshop and have not had time to complete the amp layout (gotta have a place to store all of my projects ). I should be able to finish the layout within the next two weeks (as long as everything goes according to plan). I will be posting the gerbers when I am finished and possibly after I test the amplifier. I have to make sure that the amp is stable.

Let me know if you have any further questions.

Sean

Hi Sean, don't worry, I'm not hasty;

tino96,

I have finished the PCB layout and will be posting an updated schematic within the next few days. I will be getting the prototypes made within the next two weeks. I will test the boards and make sure there is nothing wrong with the layout before I post the layout and gerbers.

Hi TucsonSean, good news!
I'm wait

Ciao TucsonSean, you've tested the amp?
some wrong?
smoke and flames?
I hope that's all ok!
I'm wait
bye

tino96,

Sorry for the long delay in everything. I just got my boards back (10 in all) and am in the process of building one up. Unfortunately I have to leave on a trip for a couple of days so I will not be able to finish building until this coming weekend. Everything looks good with the new boards and I haven't found any wrong connections. All should proceed well. I will keep you updated on the progress.

Hi Tino96,

Incase you haven't already seen it, I posted a board layout for this design a few weeks back. Since then the amps have been fully tested and work fine.

The board is a little on the large size but why make it small and fiddly when youn have the room??
The file is in Traxmaker format.

Matt.

for matth:
many tnx, I didn't see your work, (I have little free time).
Now download your project and traxmaker
Bye.

for TucsonSean, don't worry, I've think only that you don't remeber me. When your work is ok, tell me.
Ciao
