Hello,
a little while ago I got the two boards with the MOSFETs off the US and finally handed them to my friend's Ciro capable hands, the cabinet also made it to the lab and now it's about transformers, caps and all the other stuff.
I have no experience whatsoever on build and even tho I read tons of threads I don't feel skilled enough nor have the tools to build such a thing that's why I asked him, who is a very competent guy in this field to do it for me but there's quite a few thing I'd like to know before going any further.
We decided on a dual mono in a single chassis, two 225VA transformers (might be bigger depending on what's available at the supplier), capacitors I forgot what he mentioned but for the whole thing it will be in the 250 euros range (!!!), then I asked if a soft start is necessary but he said it is not, then since I want a front switch (any suggestion at where to look to have an idea of what to get? I guess typical are the round ones in Apple's style with coloured led light, I want the less flashy possible thing, I picked black 4U case and it HAS to match!) he said it will take a relais to command the power section.
What should I discuss before he jumps onto the build? Any hint you can get me?
By the way, still freaking because of my 90db/w speakers (Old JBL L220) and preamp, about same age, AR SP9, hopefully they match well together...
Thanks for your time
Giovanni

fat 10R NTC ( current surge limiter, as Vendors call them) is good enough for soft start in 230Vac realm
CL60 of better
