Umm, no... I get 34,.. V, so i guess iv made a mistake somwhere...

Found a wery useful information about similar circut here: https://tangentsoft.net/elec/tread/pguide.html#rwatt

All of the resistors should be ¼ W types, except for R2 which should be ½ W in most situations. When R1 is 120 Ω, R2 must be under 2.5 kΩ to have less than ¼ W dissipated through this path. R2 has to be even smaller if you use a 100 Ω R1, no more than 1.6 kΩ to avoid burning it up. Even when ¼ W is sufficient, you may want to use a ½ W unit anyway to keep heat in this resistor down, improving long-term accuracy.

I think thats what happened to my pot.
