Specs:
- input min.6Vac up to 14Vac, max.16Vac
- output any voltage up to 15Vdc
- max output sustained current 4A
Output voltage can be changed by R7 value.
R7 = Vout x 10Kohm
PCB + Saligny LC = 30euro shipped by tracked mail envelope 8euro.
Full mounted = 65euro shipped by tracked small parcel 22euro EU, 38 euro worldwide.
For EU citizens, 19% VAT is not included and will be added at the end of your invoice.
For EU VAT registered companies, there is no VAT.

For EU no 19% VAT included.
I think the "no" is typo.
IMHO indication of the gross price would be better.PCB + Saligny LC = 30euro shipped by tracked mail envelope 8euro.
Full mounted = 65euro shipped by tracked small parcel 22euro EU, 38 euro worldwide.
For EU no 19% VAT included.
Outside EU there is no VAT.
Thank you for observation. I have corrected.
For EU citizens, VAT is not included and will be added at the end of your invoice.

Tibi, just from the top view of the pcb it looks like the LT3042 pin 9 is not connected directly to the main bulk output cap '+' pad, and the regulator input is not taken directly from the large bulk e-cap '+' terminal. Was that intended, given the module is marketed as 'ultra low noise' ?
Trobbins,
Yes, the way that pin 9 is sense pin and make a Kelvin connection to one of the ceramic output capacitors. It was intentionally made such way.
Regulator input is taken trough R1. This limit current trough LT3042 to ~60mA.
