The 6DJ8 tube headphone amplifier is suitable for use with many Hi-Fi headphones.
#Stereotube driver
Gain is sufficient that no driver stage is required for the tube amp.

The amplifier circuit is push-pull and biased into class-A operation with a CCS. The simple tube headamp uses one 6DJ8 (ECC88) tube per channel. This low power tube headphone amplifier project comes from Bruce Heran. This is a great simple preamplifier unit to bring out the most in your power amps.ĭIY 6DJ8 (ECC88) Tube Headphone Amplifier - 24 November 2012 The Universal preamp is fun as it allows tube rolling to compare various tubes in your stash. The preamp uses a 6CA4 tube rectified power supply which is very quiet. You can change the tube type to vary the sound and gain considerably. The 4S Universal preamp is a Super Simple Single Stage (4S) line level Hi-Fi preamplifier that works well with the entire range of 12A*7 tubes - 12AU7, 12AV7, 12AY7, 12AT7, 12AZ7, and 12AX7. This is a great sounding 300B triode amplifier that I am sure DIYers will find very rewarding.ĤS Universal Preamplifier for 12A*7 Tubes - 15 December 2013 The audio output transformers are Lundahl LL1623. The power supply filtering sections have been duplicated for each channel for this 300B triode amplifier and premium parts are used throughout. The 300B SET amp uses a 6SN7 direct coupled driver stage and an all low mu triode array. As a thank you for the 300B amplifier schematics, Stamou has shared his implementation of the 300B single-ended tube amplifier schematic by J.C. This DIY 300B triode amplifier project was completed by Stamou Tasos who is from Greece. Matt reports that The 6EM7 amplifier sounds wonderful! The bass is well articulated without being boomy, mid-tones are clear and even, and the highs are crystal clear.ĭIY 300B Single-Ended-Triode (SET) Hi-Fi Amplifier - 24 March 2014

The 6EM7 SET amplifier uses a 6CA4 tube rectified power supply with excellent channel separation and which is very quiet. The single-ended 6EM7 amplifier is housed in a vertical wooden chassis that has been styled after early vacuum tube equipment of the 1920s. The clean output power from the 6EM7 SET amplifier is about 2.2 Watts per channel with a frequency response that matches the audio output transformers.

Matt describes the design and construction of a Single-Ended Triode (SET) amplifier built around a pair of 6EM7 double triode tubes. I highly recommend that anyone looking for a little iPod or computer amp give this one a try.ĦEM7 Single-Ended Triode (SET) Amplifier - 29 June 2015 I currently have a set of NOS Sylvania tubes in it, but I have also used a set of old used GE tubes which sound just as good. Matt reports: This is quickly becoming my favorite amp. The 6CY7 stereo amp uses a 6CA4 tube rectified power supply with excellent channel separation. This amplifier did a little better than this having a -3dB bandwidth from about 46Hz to about 30kHz. The Edcor XSE output transformers are rated from 70Hz to 18kHz.
#Stereotube full
At full output the amp produces a clean 1.3 Watts output per channel into 8Ω. This inexpensive Single-Ended Triode (SET) amp is built around a pair of 6CY7 vertical deflection dual triodes built for TVs. The circuit is biased into Class-A, ultra-linear operation and output power will be dependent on the tubes utilized.ĦCY7 Single-Ended Triode (SET) Amplifier - 30 July 2016 The JBAA tube amplifier can use a 12AX7, 12AU7, ECC82, ECC83, 5751, 12SL7 or 6SL7 in the driver position while 6V6, 6AQ5, 6005, 6Y6G, EL84, 6BQ5, 6F5P, 6P15P-EB, 6Y6GA, 6K6, 6W6, 6GV8, 6BM8, ECL82 or ECL85 can be used for the output tubes. The schematic is similar to the PoddWatt design and able to use a huge variety of tubes. High Fidelity Tube Junk Box Audio Amplifier - 10 November 2019īruce Heran outlines the design and construction of a High Fidelity Tube Junk Box Audio Amplifier (JBAA). The input stage is a SRPP design and can be used with 6/12SN7 or higher gain 6/12SL7 preamp tubes. The amplifier circuit is biased into Class-A, ultra-linear operation and output power will be dependent on the tubes utilized. The Cranberry tube amplifier can be used with pentode or beam power vacuum tubes like 6L6GC, E元4, KT77, KT88 and KT120. Chronological list of our DIY vacuum tube Hi-Fi audio projects.Ĭranberry TwoC - All Tube Stereo Amplifier - 17 January 2022 NEWīruce Heran describes the design and construction of the Cranberry TwoC a stereo integrated all tube amplifier.
