Default TDA1541A - Increasing the Voltages?


Is it possible to increase the supply voltages to a TDA1541A (in a similar way as can be done to the TDA1543) ?

Has anyone done this ?

Are there any gains to be had ?


If it ain't broke, break it !! Then fix it again. It's called DIY !

Yes, you can..... but, look at datasheet, little tollerances are allowed....

for the +5V and - 5V you can up and down for 0.5V only. For the -15V there's a 1 V margin.

But -5V is actually -6V in Marantz CD-94. I think the -15V is also -13.5V (not sure about the latter).

Yes -6V in many Philips/Marantz players!
