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. ### ⭐⭐⭐ 3.0 out of 5 stars Not too bad *by E***N on Reviewed in the United States on October 29, 2016* Not too bad but not as good as Mullards re-issue ### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars Five Stars *by J***N on Reviewed in the United States on December 9, 2015* Perfect replacement.
