"Good real NoS GZ34s which are the ONLY good GZ34s around now,"
Did you try the recent releases - the Genalex U77, or the Tung-Sol or Mullard branded 5AR4/GZ34s?

This was back in the mid 90s, and we put a third Nichicon 400V 470uf cap where the octal socket was. The bass duty amp had a 4th cap underneath. Click below.I briefly used a DH VR, a 5AS4?, whose heater current draw was too high for the PTs.
And both amps sound fine. Slam, nuance, etc.
And, in their new role driving 63s strapped to mono blocks (40W pentode) and filtered 150Hz 1st HP, they won't be working all that hard.
We've replaced some valves.
I am happy.

There are a lot of people who don't realize how good the 3 rectifiers I mentioned are, so I thought I'd ask if you knew of them.
