BELOW FROM EFFECTRODE'S TUBE/VALVE DELTA-TREM 2B PEDAL OWNER'S DESTRUCTION MANUAL. ODD AS IT MAY SEEM, THEY ARE A UK BASED COMPANY, BUT I HAD TO TRANSLATE IT INTO ENGLISH FOR THEM. (?)
AS SUCH, I HAVE IMPROVED UPON THE ORIGINAL. FEEL THEY CAN'T SUE FOR THAT REASON, ASK ALL THE GREAT BLUES MEN FROM 1930s CHICAGO.
to extend (vacuum) tube (or valve) life, it is recommended that the unit be allowed to warm-up for at least one minute...
HERE, I WOULD ADVISE AT LEAST 5 MINUTES, IF THAT SEEMS TOO LONG; CALL IT 300 SECONDS INSTEAD.
...after being switched on. this is to allow the heater filament in the tube (valve) to heat the cathode, which is coated with a layer of barium and strontium oxide. the oxide layer gets torn off the cathode in a process know as "cathode stripping" if the cathode has not reached the correct operating temperature. (before being used to amplify a signal) if operated well within their (temp) ratings, good quality signal tubes (valves) can last 100,000 hours or more: that's well over 11 years of continuous use. [if you use your pedal (or electronic device) for only 4 hours a day, they should last over 25 years.]
THEN THERE IS A DISCLAIMER THAT THE MANUFACTURER WILL NOT WARRANTY RECENTLY PRODUCED "TUBES/VALVES" TO LAST THAT LENGTH OF TIME, AFTER RECOMMENDING "JAN" DESIGNATED PRODUCTION FROM PRE-1960ish TIME PERIOD.
SO WHAT ARE 300 SECONDS COMPARED TO A POSSIBLE 25 YEAR LIFE SPAN? DON'T PLUG IN GUITAR CORD OR LEAVE AMP ON "STANDBY", IF SO EQUIPPED FOR 5 MINUTES.
BEFORE RETIRING FROM THE AIR FORCE, MY FATHER RECEIVED A COMMENDATION FOR SETTING THE RECORD OF CONTINUOUS OPERATION FOR THE OLDE SCHOOL TUBE/VALVE IBM COMPUTER JOINED TO THE RADAR AT BLAINE AFS IN WASHINGTON STATE. HE DID THIS (PARTIALLY) BY CHANGING OUT THE TUBES/VALVES BEFORE THEIR USUAL AVERAGE LIFE HAD EXPIRED.
JAN (joint army navy acronym) TESTED TUBES >COULD< LAST FOR THE ABOVE QUOTED TIMES.
