Orange terror on/off etiquette

[Black Coffee]

I’m the owner of an Orange 500 terror bass head and I understand the standby for 2 mins while turning it on, but do you need to leave it at standby when turning it off?

Maybe sounds like a total newby question but all the online content talks about everything to do with Standby on power up and nothing about Standby on power down

 

cheers

No, you don't.

Standby during power up allows the heater filaments to warm up the cathodes to operating temperature. No harm will come to them if you don't bother using Standby and go straight to ON, you just won't get any sound for a few seconds.

No need to go through standby when turning Off - just switch the amp off.

Thanks Japanaxe.

Instinctively I thought that was the case, but didn’t wanna wreck the head.

The original reason for the standby switch was to protect the power supply capacitors from getting an over voltage before the tubes were warmed up. That was a concern when it came into use in the 1950s, when caps were expensive and switches were cheap. Caps are much less expensive today, so the problem that the switch addresses pretty much doesn't exist today.

@Bill Fitzmaurice, doesn't this apply only to all-valve amps?

When I had an Orange Terror it never even crossed my mind to worry about stand-by because it's a Class D power module.

Or am I getting that completely wrong, as usual?

SS has no need for a standby to reduce voltage inrush. The voltage inrush with the power supply for the pre-amp tubes would be insignificant. What prompted Fender to employ the standby switch was their use of high power output tubes, like the 6L6, with pretty much the least expensive power supply caps they could find that would work in the circuit.

I put mine in standby mode first but it ranges 30 seconds to several minutes, if I get distracted. I think Orange gear is pretty robust and if we look after it, generally it lasts.
