## Questions & Answers

**Q: What does "STR" mean ?**
A: "STR" stands for "Special Tube Request" and that simply means Tube Amp Doctor had specs in mind that they needed included in this tube. It refers to one or more specs that were required by the manufacturer for this tube.

**Q: Are these burned in at 72 hours prior to shipping?**
A: Tube Amp Doctor claims that the tubes are burned in at their factory, but the length of time in which they are burned is not specified.

**Q: How can these be ordered to fit a Mesa Boogie amp?**
A: These tubes measure 4.48" high and 1.41" wide.  I would measure the physical space needed in your amp to install these tubes. If your question refers to the ratings of the tubes in the set, Mesa amps work best with middle numbers and when sending tubes, we pull middle numbers for all tube sets unless otherwise requested.

All I can say is 'WOW'. Had a Blackstar HT Stage 100 that lost a tube. Because tubes are typically 'matched' I replaced as a matched set. Once I found the proper bias voltage (and where to measure it), these tubes literally, leaped to life! search you tube for my extremely nerdy video on replacing tubes on the HT 100. Very very very very very happy I decided to stay with the Tube Amp Doctor brand for replacements.
