[QUOTE="pwatts, post: 873034, member: 146"] Easy to do, chassis usually is the biggest annoyance. Throw a 50VA transformer, rectifier, capacitors and maybe some inductance for gees, and top it off with regulation of choice. Personal favourite lately is TPS7A4700 but needs a decent PCB, or something in the middle until reaching the cheerful LM317. Spice to taste with decoupling caps from the organic polymer, NPO ceramic or MKP / PPS film varieties. Otherwise go with a full-on discrete affair although I doubt it's worth the cost and effort for a pre-regulator external supply. [/QUOTE]
