RFT ECC 81

[Oregon]

So, years past while educating myself as to the wonderfulness of all things "tubey", I ran across this odd old 10-pack of what I understand to be RFT ECC81 tubes. Popped 'em in, thus far, things appear Okey Dokey.  May know more tonight after they've had a chance to warm up, run in for a bit.

Thoughts?

Don't know much about tubes but seeing the picture of the VTL, I wonder if they are a tad inconvenient to plug in based on the room that one has. I have Manley phono and preamp and I thought they were cumbersome to roll tubes but seeing this picture I feel that the Manley's are a little better off with tube placement.

OK. Ran 'em for about 12hrs, they were not fatiguing at all due to the highs being rolled over. Amperex or Telefunken going back in.

Telefunken restored the sparkle lost to the RFT's.

This is why the only tubes I have are a few small signal tubes that should last for ages. It in the DAC.  Can’t do tube rolling anymore. It was addicting.

Are those in the Brinkmann Nyquist? If so, then we should have no issues for years to come...😁

Bob, you see them lit up on the right and left side.  I was told they could last for over 20years and they are small and not taxed at all.  I wish I knew more about tubes.

Me, too.

Many have told me to upgrade the Atma tubes, but I hate to make changes that I don't fully understand.- though tube rolling does sound like another rabbit hole to go into...
