However i will take a different route as far as the power supply is concerned.
I bought a dedicated low noise Audio Powersuply (picture attached) for about 23 EUR from AliExpress.
This supply delivers +24V, -24V (about 6A) as well as 12V (1A) for auxillary devices. (adjustable within 10%)
Bit overkill maybe - but it should be able to get about 30W of clean power out of the LM1875t.
Supply is relatively compact and i expect building a decent amplifier with this supply should simplify matters considerably.
Output voltage of course is well regulated and remaining ripple less than typical 0.1V.
Hopefully will receive the PS in about two weeks, and first will try an unmodified LM1875t Ebay kit and do some measurements on PS and amplifier before building final system with original LM1875t and audio quality capacitors.
Will keep you informed ..
Though I only found it at a somewhat higher price, I am looking forward to hear your opinion about this supply.
