then 100u/220u (25V) - I put a pair of 220u 25vs on the power rails of <br>
each module so that's prob 98% of the FCs I use<br>
<br>
UES - 10u/22u/47u (35v ones, I think).<br>
Yeah, I do wonder if they're worth it but they're not too pricey & I'm <br>
sure there were some details in Doug Self's book that made me think it <br>
was worth it.<br>
I'm fairly KISS (keep it simple) so happy to have made a choice for a <br>
limited range of good quality parts that I know I can obtain relatively <br>
easily for reasonable costs.<br>
The UES ones are quite big in size (though think in part that is due to <br>
bipolar) and the green does look nice ;)<br>
