Replacement EL34 Mullard valves for Leben CS300X


6+ months ago I succumbed to temptation and bought a used CS300X over the internet from a German dealer. The unit was in very good condition and the sound quality has been excellent. Sadly one of the Mullard EL34 output valves has now failed and a second is about to go. I have no idea how to source a replacement quad set - though I suspect scarcity is the least of my problems. Finding genuine NOS at a reasonable price feels like a very tricky business. Does anyone have any guidance?

PS - I have bought a quad set of Golden Dragons to keep me going. I suspect there is some run-in required but it does seem as though some of the original magic has gone.

Genelex/GL KT77s or Tesla EL34L Blue.
Have been through them all and those 2 have been the best for sound and reliablity.
