In Reply to: RE: Question about tube clearance in shelves posted by NuWave on January 18, 2017 at 20:50:08
Is the peg board screwed to the back? Even though there are holes in it, removing it altogether would provide more air flow. Of course then you have to deal with hiding the cables.The other thing is make the shelves shallower, so they don't quite reach the back. I don't know if you would be comfortable cutting the antique shelves. Or the integrity of how the shelf sits on the pegs. But providing more space for a current of upward airflow at the rear would also help.
Cheers!

EDIT: I don't know the benefits of using tube dampers, coolers and rings. I have some for my signal tubes but they are still in the box. They have them for power tubes as well. That is another way to alleviate heat I would think. Then the journey of the whole tube damper debate.

I was going to slice off a couple inches from the entire back so it wasn't as deep, but the top shelf is not as deep as the rest and the turntable barely fits the way it is. The peg board comes off, but like you said I like it for hiding the cables. I cut wider slots in it behind each shelf to run the cables.
IMO I would not worry about it. The aluminum plate keeps heat off of the wood cabinet & tubes have enough air circulation. Heating from the 6550 tubes would be less than a 40 watt light bulb. That is not super hot.
