I'm building a dual channel MILA in a shallow 2U unit and need it compact so I've drawn a PCB. This is only my second attampt at PCB design and my first involving valves, so I'd really appreciate any pointers where I might have gone wrong (ie: potential sources of noise)
- Super simple layout because I really suck at etching boards.
- Ground pour everywhere. Is that a good thing? ???
- The footprint of components is either taken from measurements of parts I have, or from the datasheets. All resistors are Dale 1/2W, the 1uF and 4.7uF caps are Solen 630V
- Pads are provided for heater wires, but the intention is that the heater wires would be a twisted pair run under the board and as far away from the board as possible. Heaters can be powered by 6.3v, 12.6v, AC or DC.

Note: This initial design is provided for feedback purposes only. It is not to scale and has not been built.
Thanks for any tips
