And we, the DIYers, are always in search of the next dream amp.
All the best.
i am not in for 3 way complicated system just a 6 channel amp powered by 2050 and two subs powered by 7293. your project is overtly ambitious but i know at the end of the day, if i end up with a capable 6.2 amp i can atleast mould the parts it to better amplifiers like you without rewasting money on transformers chips etc etc again.

TDA2050 is a powerful chip. I am sure you will get awesome thundering sound with superb clarity when you will use them in tandem altogether.
Also you are blessed as you have great speakers in your possession.

So all the best and happy safe-building.

Very low component count.
What have you missed out?

Nothing sir. The zener and a resistor are hidden behind the 1uF caps.
The amp is in operation since last 4 hours or so.

I've just finished a PSU designed by sir Mile for the ML3 preamp/equalizer section. It's working great.

I was wondering if a similar PSU can be made for 6 X LM3886 chips or is that just redundant/overkill here?

If the answer is yes, which PSU Circuit of Sir Mile should I make?
