REVIEW
First off I would like to say that I was highly impressed with the Quality, Design and Performance of this  Amplifier from RM Italy.
The Owner/Operator Manual is very clear and easy to understand for the 1st time amplifier user or the more experienced radio operator/user.
It has a 1" thick Finned Heat Sink that is connected to the main board with an additional 4-3/4" x 4-3/4" variable speed fan (very quiet) that supplies more than enough cooling power for this amp.
The variable speed fan runs on a low setting when you turn the unit on and then as soon as you key up the fan goes to high mode.
Another feature I really like is you are able to run the Pre-amp without having the Amp switch turned on.
This amplifier also has a set of 6 internal low pass filter's with cut off frequencies of: 3/4, 5/8, 15/22, and 31 MHz that are manually controlled for eliminating any harmonic emissions.
It also has a built in circuit that protects that amp should your input power exceed the 25W limit.
The Quality, Design, and Performance of this Amplifier from RM Italy are exceptional and have far exceeded any expectations that I had before testing it.
In conclusion this is a very fine well working amplifier that does it all.
This is yet ANOTHER Quality product from RM Italy that Copper Electronics has added to the continually growing line of radio products for radio enthusiasts.
Respectfully Submitted,
