600W? Well, er thats a bit of overkill...LOL!

No, you just need something that will "crowbar" and keep the MB3756 from getting spiked by surges - the surges from Power line, reverse polarity as well as inadvertent overvolt from an external DC power supply.

Please note that CURRENTLY - (SIC) you don't have any true protection from any regulation issues caused by surges in the AC power supply side, only the Bridge rectifier, the DC input from External - else you have no protection from failed regulation in the Power supply itself.

If something were to happen, you have little protection from it once it's out of the power supply and on thru the power switch. After that - it's up to the protection parts that TSB describes, to protect itself.

The Fuse gives the radio the chance to survive if something power-supply wise, ever went wrong
