Shrink a tube amp

Hey

I am working to shrink a tube amp, and for this work, I lack a few rules of thumb from a few experienced builders.

The hv psu built by CLC with the final C placed on the amplifier chassis.

The actual power xmr, rectifier, the first cap and choke is built into a separate cabinet standing on the floor.

I am missing the following: 😕

1: Minimum distance between ECC8x tubes. Problem = Heat

2: Minimum distance between 6SN7 octal tubes and similar tubes. Problem = Heat

3: The minimum distance between 6L6, 807 and similar power tubes. Problem = Heat

4: Distance between tube and OPT. Problem = magnetic field

5: Distance between the two OPTs. Problem = magnetic field

And Yes i know to take care not to heat op the caps. 😀

hey - time honoured and tightly packed.
