220v power supply for LM family

Boaz · 2nd June 2004, 01:17 PM

Can anyone recommend a 220v power supply design (or a commercial one that I can buy) for the LM family?
Can I use it for the mox active crossovers as well?

Thanks,
Boaz

Start HERE fora GC PSU.

For your crossover PSU, I assume it uses something like +/- 15 volts so you could copy the design used HERE .

IF this amp and preamp are going in the same box, instead of building a whole separate power supply you could just use some regulators to get your -/+ 15V off of your amp power rails. I'm doing this with a sub amp I’m building. I used the ON-Semi MC78L15ABP, and MC79L15ABP regulators. I don’t know how it sounds yet but my voltmeter says it’s ok.
