This is getting really good now, so stop friggin'around with spice, build it and tell us how it sounds!
Points:

You are connecting the output stage's CCS to the minus 30V supply. This only adds heat to this CCS - conect the first pair's CCS to this -30V, but ground the output tube's CCS.

And i do not suggest using CCS loads for the first tubes - a CCS in the cathodes and CCS's as anode loads tend to fight each other - keep it as you have it.

When you have done it like this - none! So, for the third time - BUILD IT!
