using the snubberized PSU board with CT trafos?

linuxworks · 14th December 2010, 08:38 PM

I am planning on building a 4ch amp (for stereo, active crossover of tweeter/woofer) based on the chipamp amp boards.

I also have some of the nice red power supply boards, too; but they are all meant for dual secondary trafos.

I have a few extra 18-0-18 toroids that I want to use (or would like to try, at least) and they are true center taps but not dual secondaries. is there an easy way to 'jumper' the existing PSU boards to accept a center tap trafo, probably also using only half the diodes?

Check out Apex Jr.Home Page, there is a really easy to follow instructional about using a CT trafo with the Carlos FM snubberized power supply board. It's found under the specials or misc section of the sales pages, where he sells CT trafos from his site.
