    I had seriously considered drilling a new hole for the choke on the left, but didn't see it as viable.
    Glad to see someone do it.
    That made me kinda nutty looking at it.

    Incredibly neat but would still have liked to see grommets where the wires come through the chassis. That would have been the icing on the cake so to say....

    Almost a shame to put a soild bottom on it and cover up all that hard work.

    Well done.

    Not specifically aimed at this build but from a European perspective I cannot get my head around the way that the power cord has a knot for strain relief by design not to mention one side of the line cord switched and the other side fused. Goes against all my years of training.

    Is it my OCD showing but I just had to make my Triode/Pentode switches the mirror image of each other.

    Yes. Also just a fantastically neat job!
    If I had to build another, I would spend a whole lot more time on routing.
    I have a tendency to leave a bit more wire than I should in case of needed rework.

    I couldn't take that angles choke so I drilled it!

    I wish I put grommets in there as well.
    Good tip on the switches.
    Thanks for the complements!

    I suppose you could always use a grommet with a single cut in it and slide it in. If it were the right size the join would not be noticable.

    Makes me want to order another kit and see if I can get it as neat as yours. Mine got a little bloated once I added my tweaks.

    Neatest wiring (in more ways than one) that I have ever seen. Outstanding!!!
