Adding a Standby Switch to My Rivera R30...?

[megatonic]

I have a Rivera R30-112 and love the amp, except for the fct that it doesn't have a standby switch.
Does this shorten the life of the tubes?

Is it complicated to install a standby switch? Expensive?

You don't really need one. Just turn down your guitar vol to take a break.
