what was it's real design purpose and how do you use it correctly
1. Turn Power switch on with Standby in Off position.
2. Allow heaters in tubes to warm up tubes - approximately 30-60 seconds, at least
3. Turn Standby to On.
This allows the tubes to warm up before hitting their components with hundreds of volts. You can turn an amp on all at once, but it's hard on the tubes.
