[apexaudio]

Dear sir Apex,

Hello my PCB is complete please check if it is OK so i can post PCB layout for Diy to make Apex sir please guide


Thanking you
Sameer X1

You must use TEF output stage to drive more than 4 pair of outputs.

thanks brod MJ777.
m just wondering, the wattage output of B500, how well it can deliver into an 8 ohm load? especially to an 18 inch driver paudio 600watts aes?
or is it the H900 which has the more power?
this FARNELL u thought me about, do you have their contact nos i can reach them with?
are these parts BAV21, NSL32 & IR2117 arent available in alexan here in quiapo?

 

[kikoman46]

to sir apex

in what number did you post the power supply pcb, mainboard pcb and parts placement of the amplifier B500? and how much power does it offer?

thanks so much sir

TEF DRIVER PCB

Hi Sameerx1
greetings have you tested TEF driver pcb using BD681 can you
redsign PCB using apex TEF stage using BD681 and 8 output pairs apex amps
have very clear sound and good bass hoping you can oblige
warm regards

to sir sameerx1

i would like to ask if the circuit apex tef amplifier has already gone testing? is it 100% ok to build one? and sir what is its power output?
could you post its schematics, power supply parts placement guide and its calibration in just one post sir?

more power sir,
kikoman46

 

[kikoman46]

to sir apexaudio

is the TEF H900 more powerful than the H900 alone?
where can i get the complete schematics, pcb design, parts placement guide and its power supply?
please sir im really eager to build one of those.
and what was the TEF means, and what is it for?

 

[irvynejay]

all file of this h900 already been posted and tested you have to read the whole thread so you can find what you need ,proper wiring ,measurements and how you know step work all are here you need to give some time to read this thread

hi kikoman46,

just read the whole thread from the beginning so that you will know all the steps. schematic,pcb layout, component placement,power supply requirement, DIYers and ..etc.

to irvynejay and nix

thanks very much men. i really need to read alot. and im going to build a great amplifier.

nice day my fellow citizen

kikoman,
there are two version of h900 board
i use the version 2 board with back to back diode or double diode
they are right just give it a time to read,whole thread reading is good if you can give time
but you can also prefer just reading maybe first 10 or 20 page all info to built is there,
just manage to get all parts that is available to you,all hard to find parts are pinpointed to you by some member,
manage first to get ir2117,bav21 and there you go
regards
