sorry for my english, 'local speakers' I mean the speaker of domestic production and not including the high class speakers.
this is my AX16
and this is AX16 with PSU + Protect, transformer 5A CT 45V
Nice work, this PSU already have short-circuit protect you don't need overcurrent detect from AX16. With this PSU you can use AX14.

whats the different between ax14 and ax16, output power how much? how is the sound quality.
if u can pls share the top and bottom pcb layout in pdf format.
yes sir but next i want build AX500 and use protectors such in use h900 protector, that's the reason why i build lay out AX16 because make it easier to add a pair of transistors final.
Yes, but this PSU with protect can be use for any stereo amp around 100W power per channel.
another one question.
how to check the ampere of the transformer on output. there mension in the transformer how much ampere. but what is the actual ampere in the transformer.

BT139 can be use instead MAC224, and I suggest this circuit.

in this two images the zobel section pcb there are two caps 47nf/250v and 100nf/250v which one is correct?
hi apexaudio
greetings can you please explain working of circuit in event of dc at speaker output terminal does it blow supply fuse or dissconect speaker i think qsc amp use this type of protection
thanking you

I've listen UB40 from phono (Thorens TD160, Ortofon OM40), and I only can reapeat your expresions and highly recomanded to all.

Yes QSC and many other amps use this protect, it's blow supply fuses and speaker is safe from dc.
