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

In this age of low or no-maintenance consumer goods, where you’re more indubitably to toss your DVD player in the nearest Dumpster and flap by the local big box retailer to pick up another one for £20 than to in fact get a small fault repaired (which, no conviction, would cost you considerably more than the new unit), the fancy of routine maintenance for electronic goods has mostly fallen by the wayside. Genuine all-tube guitar amps, however, even tag new ones, are not like other consumer electronics products; they are the archaic technology of a of old era, and thanks to that they can sound sweeter than any envision box of bits that has been conceived to replace them. As such, though, they difficulty a regular check and tune up. Conduct towards them right, and they’ll reward you not only with stunning emphasis, but flawless performance.
I have known plenteousness of guitarists who were very much into tube tone, but went from amp to amp with a turnaround deserve that found them changing amps every couple of years or so—coincidently, about the amount of time it took for the new tubes the amp came with to thrive a little tired sounding, and for a few other lesser maintenance items to raise their heads. Re-tubing an amp is something you can almost always do yourself (although some secured-bias amps will require rebiasing when efficiency tubes are changed, and that’s a job for a professional).
If you are gigging or even rehearsing regularly, yield tubes are almost certain to need replacement every two years at first, and possibly even every six months or so if you are really playing a lot. Even tubes that are sonically “skilful” can become noisy or microphonic, and thus command replacement. Preamp tubes usually last a lot longer, but it’s worth swapping in a spry, high-quality preamp tube in the preamp and viewpoint inverter positions every so often—ideally after you have put in new output tubes—to see if it perks up your amp considerably. If so, you’ve got a stereotypical preamp tube or two on your hands as well. Find the wrongdoer by process of elimination.
