Hi Peter and another warm welcome to the Forum.
I restored one of these Philips 141U sets a couple of years ago so here is a link to that Thread some of which may be helpful:-

Easy to work on and has the standard range of valves for that period, but in quite a small case, so nothing too challenging or esoteric!
The set is attractive when illuminated but does have a tendency to run very hot!
