garbage · 4th March 2005, 01:33 AM

hi all

i finally got my BrianGT lm4780 chipamp singing.
the problem is that i did not solder in a 10k Rm.

currently there is no cap at C1 and C2 of the amp board.
what cap size should i use for a SLA battery powered lm4780?

thanks

You might go as low as 10 - 33u, but I would not disregard 100u either. Try few different values and see what sounds best for you.

( Personally, I preffered 100u over 10u).
