Bottleheads in Wood Cabinets: Tube Ventilation, Heat Insulation / Shielding?

[rsmiii]

I wish to enclose certain Bottlehead products inside a vintage wood record console.
Enclosed three sides only; more-or-less fully open to the back (out of view).
Products likely an Eros 2.0 and a Kaiju (maybe, a S.E.X. 4 instead, some day.)

As a matter of general principle:
1. How much distance should there be between tubes and the nearest wooden cabinet wall or cabinet ceiling?
2. To further ease the mind, should I consider some insulation or shielding on nearby wood walls or wood ceiling? Sheet metal; fire-resistant insulation?

Advice appreciated.

This will depend a lot on the specific product, but of what you've listed, the Kaiju and SEX4 are going to be pretty hot. I'd want 3-4" at least between the top of the 300Bs and the wood inside that cabinet. I'd also be sure there's 3-4" of space between that cabinet and the wall.

As always, you can throw a thermocouple or meat thermometer down in there to see how warm it's getting. It would be nice to see less than 80F inside something like that when everything has been running for a while.
