Always a guess when you order a casing. This one is very satisfactory! All components fit perfectly. The case was assembled without any effort.
One tip: Add exact drawings, having all dimensions makes it easier to add or adapt stuff. The end result will be even more perfect ;) I , for example, need to modify the top 'lid' to fit 3 transformers and two large KT120 tubes. Replacing the top lid with another plate is easiest but I need accurate dimension to get a good result without the inaccuracy of measuring it myself.
