>>leave the pre-amp tubes alone.  Pre-amp tubes can last quite awhile, 
>>especially if

>>you can't

>>weekend, and
>>rehearsing once or twice a week) for 5 years, you're probably due for a 
>>power tube
>>change.  If the amp hasn't seen much use in 5 years, then don't sweat it.  
>>Also, the

>>tubes will
>>tend to outlast the newer Russian and Chinese made tubes, 6L6 GC tubes 
>>will outlast 6L6
>>WGB or GB or 5881 tubes, especially in amps with higher plate voltages.  
>>For instance,

>>set of NOS 6L6
>>WGB's in about 6 months, but I've had a pair of JJ 6L6 GC's in there now
