Cheers for the help!

Would you recommend changing the pre-tubes now, along with the power tubes?

Basially, the EL34s in my OTR "120" (labelled OTR 80 but as it has 4 EL34s i assume it is a modded 80/mis-labelled 80) have been in for a fair old whack (year and a half) now they likely as not need replacing...
