I absolutely don't know how to chose one !<br /><br />ThanksAnonymousnoreply@blogger.comtag:blogger.com,1999:blog-4393219521080697284.post-15089997757589998402013-08-22T00:21:33.493+07:002013-08-22T00:21:33.493+07:00Thanks for the very quick response, Lil' Knigh...Thanks for the very quick response, Lil' Knight.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-4393219521080697284.post-52839402856208395892013-08-22T00:01:47.612+07:002013-08-22T00:01:47.612+07:00Yes, that's correct. I forgot that the quantit...Yes, that's correct. I forgot that the quantity is for 2 amps, so just use half of it for a single build.<br /><br />1/8w and 1% resistors is fine. The board could take up to 1/2w resistors.<br /><br />A dual S22 configured for 30v is recommended. Dual 30v+30v/80va transformers would be perfect too.

(e.g., don't go above 1/4W or use Vishay RN series, otherwise the resistors won't fit?) <br /><br />Many thanks in advance for your help.Anonymousnoreply@blogger.com
