Yes, 250VA per channel for the OPS. How is your amp doing, Pieter?

Hi Michael, my B24 is doing very well. I paired the B24 (with high damping factor) with pmc transmission lines, so bass control is superb. SQ overall with B24 is very good. I enjoy B24 very much!
W.r.t. e24, I experience an unexpected switching every 4 or 5 months or so. It is somehow sensitive for upstream power events in 230v network involving switching power supplies.
I am currently building a preamp with A24. For the vol control part i bought a ready made maya unit as I lack time to also assemble Ti's vol control.
Your new dc protection needs external power, right? What type of psu does it need?

This problem was mentioned lots of times in E24 sub-forum. Have a look here http://www.bowdenshobbycircuits.info/page9.htm, under "High Current MOSFET Toggle Switch with Debounced Push Button.", there you will find the solution.

The DC protection boards are powered from the Sigma22's Vreg+.
