PCB layout for "constructive" criticism

[v4lve lover]

Ive had good experience with Eagle in combination with the TopoR autorouter.


I like TopoR because it will auto route without any defined angles and automatically keeps the clearance in check. Plus it looks quite retro.

Layout was done in DesignSpark which I've used for many years. Some kind soul has created a library of valve footprints.

Kind soul indeed-
I use Fritzing, but no tube footprints are available. Think I can create them from .svg file exported from DesignSpark, and import into Fritzing- hmm.

Sorry for getting off topic, carry on

This is the tube library I've used
