    I should have used an intro there.....I didn't "say" anything in post #79. I simply posted a technical expanation for the situation. I'll edit...

    standby..use 'em if you have 'em adn want to use 'em. Be aware that cathode poisoning is a reality and occurs when the circuit has been left in that standby mode for long periods....decreasing the integrity and life of the tube.

    If I didn't say it earlier, the only amps that demand that I use the standby on are amps that have a lot of relays that Pop! when the circuit is shut down with full voltage present in the circuit. The standby is not needed for firing the amp up, but it is needed when shutting the amp down...unless you like hearing those relays Pop, Pop, Pop.....
    The standby is useful when changing cables or instruments.

    then, if the designer of that amp knew what they were doing and installed caps with sufficient votlage capabilities, that amp does not need a stand by switch.....as stated in that quoted explanation I posted in #79.

    Why does the Marshall DSL15H have a time delay with an audible click a fraction of a second after you turn on (or off) the single power toggle?

    BTW this amp has no standby switch, it has a solid state rectifier with all tube preamp and power (came with TubeAmpDoctor 6V6's believe it or not).

    That might be a relay popping as teh circuit draws down.
