wrong! It is a reservoir for secondary side current demands.Primary side bulk storage is only of use as protection against brown-outs. It contributes precisely zero to secondary side current demands in excess of the current limit.

Indeed yes it is - but note I didn't say 'secondary side current demands', I qualified that.
So your 'wrong' is in fact itself wrong.
Thanks ! I will try to make out what I can from the link you provided.
When I eventually get mine I'll initially be looking at the power supplies to the TL072s to check that the switching reg isn't putting HF on their rails.
1st project - looking at TPA3255
Attempting Large, just portable, bluetooth battery powered speakers.
Would it be best to go 4P3S with 18650's and get 48V with something like this ?
Or just go 11S 46.2Vmax with a 10A fuse ?
Or some other way ?
Advice very much appreciated.
PS. I have a 6 cell balanced charger so maybe it would be sensible to go 2P6S and just run it at 25.2Vmax
Would I be able to get about 2x30W at low distortion like this ?
Hi, I'm new to the forum.
My TDA3255EVM will be shipped in a week or so, can't wait!
The only PSU I can get for free is a Siemens Gleichrichter GR 1500W Rectifier (S30050-K6383-x-1), label says 48(54)VDC and 16(14)/31(28)A on the output stage.
What do you guys think? Overkill? Hell yes!! But would it work nicely with the TPA3255EVM?
I will only drive bookshelf speakers for now. Ironic since I dont like to listen to music too loudly (like quality over quantity), but I have the biggest PSU on the forum?
