Tone Tips: Tube Amp Maintenance
 Another practical insight into the world of amp care, thanks to those guys at Gbson…Like reasonable about anything worth owning, even the best tube amplifiers on tap need occasional maintenance to proceed performing at their peak.

In this age of low or no-maintenance consumer goods, where you’re more inclined to to toss your DVD player in the nearest Dumpster and waggle by the local big box retailer to pick up another one for £20 than to in truth get a small fault repaired (which, no incredulity, would cost you considerably more than the new unit), the general idea of routine maintenance for electronic goods has essentially fallen by the wayside. Genuine all-tube guitar amps, however, even label new ones, are not like other consumer electronics products; they are the archaic technology of a olden era, and thanks to that they can sound sweeter than any inventiveness box of bits that has been conceived to replace them. As such, though, they demand a regular check and tune up. Take up them right, and they’ll reward you not only with stunning emphasis, but flawless performance.
I have known numbers of guitarists who were very much into tube tone, but went from amp to amp with a turnaround place that found them changing amps every couple of years or so—coincidently, about the amount of in good time dawdle it took for the new tubes the amp came with to breed a little tired sounding, and for a few other minor care items to raise their heads. Re-tubing an amp is something you can almost always do yourself (although some arranged-bias amps will require rebiasing when harvest tubes are changed, and that’s a job for a professional).
If you are gigging or even rehearsing regularly, create tubes are almost certain to need replacement every two years at excellent, and possibly even every six months or so if you are really playing a lot. Even tubes that are sonically “gentle” can become noisy or microphonic, and thus make replacement. Preamp tubes approximately last a lot longer, but it’s worth swapping in a strong, high-quality preamp tube in the preamp and end inverter positions every so often—ideally after you have put in new produce tubes—to see if it perks up your amp considerably. If so, you’ve got a trite preamp tube or two on your hands as well. Find the offender by process of elimination.
