Thank you. It's a bit hard to make use of, as I only know English.
I see the link to eBay for 5 V SMPS, but any I've found can only be trimmed +/-
10%, so giving a maximum output voltage of 5.5 V, so it seems that one will
have
to be lucky to find a SMPS which works to 6 V.
That's why I looked at a 7.5 V SMPS. I doubt that can be trimmed to 6.0 V, but
at least one can drop the 1.5 V with a resistor.
Your not the first to suggest a 5 V SMPS, and I doubt you will be the last, but
getting 6.0 V seems outside the spec of any I have found.
