Trainwreck Blues tube amplifier for Guitars
This revision reduced the signal level and treble response in the preamp for a smoother sound in both cathode and fixed bias modes. The power supply was also revised for lower B+ voltages to the EL84 plates. This amp was...

700W Amplifier. Adjusting the amplifier power to 700W appears straightforward, yet it is essential to consider the adjustment of the driving transistors and the frequency offset engagement. It is necessary to modify the current protection circuit that safeguards the final...
push-pull 300B power amplifier
Most devices used in amplifier output stages exhibit significant non-linearity, with transistors (both bipolar and FET) being particularly problematic. These components are almost always employed within a global feedback loop to mitigate their non-linear characteristics. Similarly, tetrode and pentode valves...
Audio peak Indicator
This circuit can be used to remotely monitor a loudspeaker, alarm, or audio source for presence of an audio waveform. It can also be directly connected across loudspeaker terminals used as a peak indicator. If you need to monitor some...
Automatic Audio Shutoff
The purpose of this circuit is to automatically turn off any device plugged into its power outlets after a certain period of time. Shutoff is activated by an absence of an audio signal or by a standard timer function. This...
Automatic Loudness Control circuit
To achieve optimal audio reproduction across various listening levels, it is essential to adjust tone control settings to accommodate the known characteristics of human hearing. Human ear sensitivity changes in a non-linear fashion throughout the audible frequency range, as demonstrated...
Bridging Adapter For Power Amplifiers
A stereo power amplifier is limited in its output power by two main factors - the impedance of the load and the internal power supply voltage. To obtain more power, one has very limited choices - other than the purchase...
High-Power Car Audio Amplifier
Note for bridge configuration: 1. Install jumpers JU2 and JU4. 2. Remove J1. 3. Remove RIO. 4. Replace R13 with a jumper wire. 5. Replace R15 with a 4.53 kΩ, 1% resistor. 6. Replace R14 with a 13 kΩ, 1%...
Aikido octal mono PCBs and 5687 PCBs and Aikido and 300B amplifiers
Buffers are a specific category of amplifiers, and power buffers are a subset of power amplifiers. The defining characteristics of all buffers include unity gain and a low impedance output, ideally accompanied by low distortion. When examining commercially available buffers,...
