6H30 replacement

Hi Mike - I have been thinning the herd, i am down to just 2 turntables…ha.

I ordered a pair of curve tracer matched Mazda from Brent to roll into the Herron. We shall see…..or hear…

Has anyone found out if the amp can sub 6n6p for 6h30?

Pathos will not give me any technical information, beyond saying that the amp is designed for the 6H30. 

6n6p specs look similar to the uneducated eye. 

@mulveling What do you think about 6n6p as a direct replacement for the 6H30? 

I have been reading in the ARC forums that some use them and like the dynamics and not as in your face. 

Victor Khomenko (BAT), commented in a forum they are not exactly and might not last long so to buy a lot of them.... :) 

Any thoughts?

Not certain what the 6h30 does in this unit.

The 12ax7 is used for input/gain and wonder if the 6h30 is somehow used as a driver for the SS amp section, otherwise I don't understand why it's even there.

If it's run @ a lower bias than spec'd for the tube, then 6n6p may be a candidate as others have used it successfully as a sub in DAC's and some preamps in which the the 6h30 is ran @ lower values.

Also confused as to why the manufacturer cannot answer (what would seem to me) a simple query.

to be honest, if it is a nice, expensive piece of tube gear, and the manufacturer or dealer won't give straight answers about how the tubes work in the circuit, and speak to reasonable substitutes (or lack thereof), it would be enough for me to move on to something else
