Hi guys,
 
Wanting to know what tubes can be used with an adapter for the Feliks Audio Espressivo, they are the power tubes and the pre-amp ones are 6N1P (E88CC compatible etc...)
 
I know 6SN7 can be used as pre-amp tubes with adapters but not sure what power tubes can be used,
 
I have heard the C3G can be used in place of the 6N6p with an adapter but not sure which others might work,
 
What specs from the manufacturer would I need to let you guys help me?
 
Thanks!
