Allnic 1201 replacement tubes?


Hello all ...I have an Allnic 1201 phonostage and I think the Mullard E180CC’s are nearing the end . Should I pick up the same NOS Mullards are there alternatives where I won’t lose performance? 
Also they seem difficult to pull . Like they are loose at bottom and will just rip apart but I might be overthinking it..? Thanks

pretty sure its a cold solder joint in my Manley preamp , it seems to have gone away for the time being ...

I've swapped tubes L/R , its really intermittent ...
Hi Tommy
