Changing tubes of ENGL Savage

nmorchyths · 02-12-2008, 08:00 AM

Do you change the tubes all by your own or do you think that I have to bring my amp to a pro to change them?
I want to change all tubes.

I always take mine to a tech, i don't want to be responsible for frazzling expensive amp innards

All you have to do is unplug the old ones and plug in the new ones... It's not that hard.

The Engl's have adjustable bias, so to get the new power valves working properly, bias adjustment is necessary. It'd work ok if you just pulled out the old ones and and shoved the new ones in, but it's a waste because they probably won't be working their best.

Pay a qualified pro to do that.

Preamp tubes are plug and play. Very easy to change, just be careful about getting fingerprints on them or they will not cool as easily. Though this can cause more of a problem with power tubes than preamp tubes.
If you need to change power tubes, you absolutely must have it biased by a tech. In some amps like Mesa's, this isn't as crucial, especially if you replace the tubes with ones that Mesa sells since they are very close to the original specs.
But in Engl's and other amps with an adjustable bias, you really need to have it dialed in by a tech once you replace the power tubes. Otherwise the amp may run too "hot" or "cold" which can have a negative affect on your tone and output volume, as well possibly damage the amp. It will still work if you don't get it biased, just not as well as it should. Basically what seedsofthesuffering said is 100% correct.
