I no longer have my Viva Aurora's and have my extra NOS 845s for sale.
Also, you are aware I'm sure that you only need one pair of good 845s for output. The rest just buy the regular cheap chinese. Mine used the 572 tube for driver. I'm assuming yours is a 211. 211's are inexpensive usually for NOS.
