We have always recommended that you provide at least one rack unit (RU) of space above and below our products. This is especially important for the more complex products like the VT-7 Compressor and the VT-5 Stereo Equalizer, which have many tubes and generate considerable heat while operating.
We have designed a 1.75 inch (1RU) ventilated rack panel that is painted with the same high-gloss polyurethane paint we use on all our products. The rack panel has a small D.W. Fearn logo and vacuum tube icon in the same gold that we use on the products.
These panels are made of .25 inch laser-cut and milled aluminum.
