Now, as a follow up to my last post I have an interesting tube rolling suggestion based on my lp-3a which has 9 pin sockets. The rear driver is a 6cg7. Up front I run Russian rocket 6h1n-eb tubes. When DH did the upgrade he suggested I try 6cg7s up front. This very much implied to me that the circuit was possibly the same as the lp-3a with octals and 6sn7 all around. So I tried the 6cg7s up front, which I have heard described as a 6sn7 in a smaller bottle. I quickly went back to the Russian rockets. It has been a good while and I do not recall the particulars but I did quickly go back. I also tried a numbers of 6dj8 variants, always ending back with the 6h1n tubes. So here is my suggestion. Those tube rollers with an Octal lp-3a try the 6h1n tubes with a 6cg7 to 6sn7 adapter. Two tubes with adapters maybe$40, so not to much invested. It might be worth an inquiry with Dennis to make sure, but my meager understanding of compatibilities and personal experience says it may be worth while. As always, let us know your actions and results.
