Hello, I am building MX50 amp. Already ordered amp modules. Transformer will be 150VA 22-0-22 as recommended and calculated on some forums and it will provide sufficient power for my needs.
Now - it is highly recommended that speaker protection board has independent power supply . Does it mean I need power transformer with more secondary windings or totally separate PS?
Are those protecting board affect sound quality? Is it better to but or make a DIY one?
thank you

Here is some earlier DIY Audio posts on the two modules plus a circuit diagram -
I tried the ebay MX50 DIY Kit, Class AB 100W+100W; Worked but problem.
Take note of the additional smoothing required by the poster.
