Hi

I am planning to assemble a 6 Channel amp with an active crossover , each amp driving highs, mids and low.

Amps that I have selected is apex ax11 for mids , ax14 for lows and lm3866 amp for highs.

Planning to house all the amp boards in one chassis with 2 toroidal transformers . 1 dedicated for ax14 and the other one for ax11 and lm3866 . I have not yet decided on the psu for these amps. I have gone through many threads where Mile suggests using psu10r and psu15. Please can some one help on this?

Much appreciated

You don't need an elaborate PSU, so either of those PSUs you mention should work (I have not built either, so I can't say that the schematic as posted on this site works without any issues). Howeever, all you need is a basic PSU, including a bridge rectifier, supply caps some 0.22r resistors (CRC design) and some bleeder resistors will work just fine for all three of those amps. You can add a couple LEDs if you want to see if it's "on", but not necessary. Then include speaker protection for each speaker and you should have a decent sounding system.

Don’t you think regulated supply could give you stable dc and less distortion?
