Hi.
I am currently recapping my API 550A eq´s and have a few questions.
In the original schematic the filtering caps for the power rails (+ - 16v) are 10/25v, but in a later schematic i have wich is dated ca 1980 these have been upgraded to 100/35v.
Is it just a question of size/value (caps getting smaller/ratings higher), that they would have used 100/35v from the beginning if they could have fitted them?
Also, in the later 554 eq schematic they also have the 100/35v caps in this place.
Should i use the higher value here??
Then there is a small 0,47 electrolytic in there.
Could not find that value in the Panasonic caps i use, but found another one that was non-polarized.
Would this be ok as a substitute?
Any advantages/disadvantages to use non-polarized caps??
And last the output cap (500/6,3v vs 470/16v).
Again this have different power ratings in the different schematics.
6,3v in the early and 16v in the later.
Would there be any audible difference??
I guess not, but i thought i would ask.
Regards,
Dennis
