TUBE HEAT IN GENERAL
Due to the design of the ZTPRE's tube layout, even if configured without a selector and completely covered by a
metal plate (worse case scenario) there would still be adequate ventilation for the tubes out the back so no worries
about overheating the ZTPRE however whatever was set on it would no doubt be overheated.
WARM UP
The ZTPRE has no unique requirements other than the typical warm up time associated with tube gear. After the
unit is turned on, the tubes will begin to warm up and glow and begin to pass signal after apron 30 seconds or so.
The best sound quality, as with all tube gear, will come some time after the 20 minute mark.
MAXIMUM ON TIME
There is no time limit or suggested maximum amount of time the ZTPRE can be left on. If left on indefinitely it will
have to be turned off for tube replacement every 6000 hours.
