Interesting posts,
My Ref40 reaches 4,800 hours now. I will need to replace 2x6550 and 10x6H30.
For 6H30, I would like to try that gold pins you wrote about, but no idea for power supply 6550.
In the pre amp chassis, I will need matched quad of 6h30 right? Each matched set per channel.
And do I need matched pair of 6h30 for power supply chassis? Also do 6550 have to be matched pair?
I am totally dump when talk about tubes.
Toga
