Line Magnetic 219ia & 518ia tube rolling


Hi everyone,

I luckily have both of these amps. I am in heaven with both. But as is the nature of the hobby I'm wondering if there is another level. I'd like tube advice. I'm planning to swap out the 12ax7s with RCA black plates or Telefunken smooth plates. Any other significant swaps that you can recommend?

Thanks,
Michael

I have the 518Ia  - I swapped in NOS Tungsol 5751s, NOS Mullard 5AR4 and NOS GE 6L6GCs - took the amp to a whole other level
