Tio keep my 'Angels' safe and dust free i bought some covers.
Wont stop hard knocks, but so much easier and convenient for everyday use.
The FA 180 has a large grill in the top to aid the ten tubes cooling. So its a great dust trap. The covers look good to me and are quickly removed when i need to crank it up.
In case any ones interested the co. is called Visiondann. Found on Fleabay, and we did a deal away from there. Blokes name is Jordan Jordonov and he is really helpful. Makes alot of different covers for many makes and i highly recommend him if your interested. firstname.lastname@example.org
