The tube audio amplififer was designed using SRPP 12SL7 tubes as the driver stage and SIPP KT88 tubes as the output stage to produce a Class A Ultra Linear Amplifier. This amplifier can be regarded as ...

We know way too little about this subject but hopefully [Bob4analog] helped us learn a little bit more this time around. He’s building his own linear amplifiers on what looks like sheets of MDF. This ...

Linear Tube Audio’s Century Monoblocks: hand-built ZOTL amps with Screen-Drive tubes, 110 W/8 Ω, low output impedance, and full balanced inputs. Just over the D.C. line, Linear Tube Audio handbuilds ...

The DALI KORE, Mission 700, and Linear Tube Audio Ultralinear+ Integrated Amplifier turned more than a few heads at AXPONA 2023. AXPONA 2023 was a necessary shot in the arm for N. American ...

The project was designed using 6T9 vacuum tubes to build an amplifier device that operates in Ultra-Linear (UL) mode. The tube amplifier circuit works better in Ultra-Linear mode which used to operate ...

Fig 1. This basic source-follower circuit is the kind of amplifier you would find in an electric bass guitar amplifier. R6 provides the feedback. On the other hand, low-distortion applications require ...

A conventional tube amplifier has a circuit whose fundamentals were well in place around a hundred years ago, so there are few surprises to be found in building one today. Nevertheless, building one ...
