positive and negative voltage regulato with LM317 and LM337. the PCB is very well made, the parts are already included in the kit. my only concern is that I am not sure if the LM items are genuine or not; the LM337 has a metal tab that is very thin, but it could be ok. the supplied heatsink can only handle a limited current, so I will replace them with bigger parts. satisfied Regolatore di tensione positivo e negativo con LM317 e LM337. il PCB è molto ben fatto, le parti sono già incluse nel kit. la mia unica preoccupazione è che non sono sicuro che gli elementi LM siano autentici o meno; l'LM337 ha una linguetta di metallo molto sottile, ma potrebbe essere ok. il dissipatore in dotazione può gestire solo una corrente limitata, quindi li sostituirò con parti più grandi. soddisfatto

  • REXX5000 yeah that's a fake regulator but I bet it works fine.. they both are more than likely fake, but they you shouldn't be having problems with them.. bigger heat sinking is a good idea. 👍🇮🇪
