You can use this circuit for bridge two amps.

im thinking of starting the construction of ax14.is this the correct schematic at post #1240?

APEX i found this schematic of yours. can you give some information and pcb?

Schematic in post #1240 is correct, and there is to many amps schematics this is B50 but only for test B500 sound in home audio.

thanks for reply.i have also seen o photo of B500 with one pair of output transistors.can you post the pcb?
so ,for home audio in the range of 50-100 watts which one do you suggest? ax14, B500 with one output pair, or something else?

B500 with one pair of output transistors is not my work.
I suggest SR100

Hi ive just recently come accross this thread and after trying to sift over all 131 pages ive become lost, hehe guess im not the brightest.
Can someone pls post the most recent working and well tested Schematic, PCB, of the Amplifier and Full protection and power supply.

Im am going to build a stereo, what Voltage and VA rating Toroidal should i buy, Ill buy one per channel.

Thanks , even links to most recent pcb etc will be so helpfull.

Ask Apex to insert the latest information and/or links to post1.

I have build PSU that APEX posted which has clipping indicator,dc protect,vi limiter and two 10000uF caps on board as well as rectifier bridge and some changes he gave me to use it with 24-0-24 transformer.its a great all in one PSU .

APEX do you have the same PSU but with four 10.000uF caps or is it possible to redesign the same?

Can i use ax-14 for PA application with two pairs of outputs with +/-65dc @ 8 ohms load

 

[shreya]

Hello Mile

can i use ax-14 for pa application with +/-65v at 4ohms, how many pairs of output transistors to be used?

Use 3 pairs of output transistors.

 

[shreya]

Use 3 pairs of output transistors.

I think there is no pcb for three pairs of outputs to this ax-14 can i use sr200 for PA it has three pairs of outputs and also need good sound quality sound even for PA speakers,does it fit for this purpose or shall i use ax-14 anyway please guide me

Use SR200 it's give best sound quality for any purpose.

In post #1284 you can find pcb design for AX amp with 3 pair of outputs.

Thank you sir but i decided to use sr200 as you stated of its quality of sound and performance
but there is no protection to it in the pcb can i add b500 protection ckt to sr200

there are so many versions of pcb of sr200 which pcb is to be used can you please suggest me

thank you
