capacitor clarity

Hi all,

Im just putting the bits into the OPL3 board and I seem to have found a bit of a problem. In the orderlist text file there seems to be 2 x 68pF caps. But looking on the board layout mbhp_opl3_v1.gif these are actually listed as 68uF. Plus around the TL074’s there are some tight clusters of capacitors in the middle of each seems to be a 68 something cap (its too close togther for me to make sens of it).

So do I really need 4 x 68 something F caps.

And what is the somethings, nanofarads or picofarads?

If you can calrify it then maybe we could alter the mbhp_opl3_v1.gif to make it easier to read the cap values which are close togther?

Lookin forward to the help!

hi dave;

something is p..

i don’t see 68uF in the gif only 68nF? this is still wrong i think, but the schematics are always the reference if you are in doubt, plus these are better readable too ;) 

so looking to the pdf you need 2 68pF(pico) caps.. continue soldering
