[AMRadio] Rack Mounting

[Rick Brashear]

I am in need of advice and/or opinions.  Has anyone had experience 
mounting a R-390 and R-388 in a wood rack like is used in  recording 
studios?  It does not have slides along the sides to help distribute the 
weight.  I've had large audio amps in this type rack with no problem, 
but I don't think any of them weighed as much as the 388 and for sure 
not the 390.

Thanks for any help or advice...
Rick
