The kit uses 2SK170 JFET transistors and comes with fabulous vintage Russian military paper-in-oil (PIO) capacitors. The builder will need to provide a 12-24VDC power supply, an enclosure and miscellaneous hardware like connectors and switches. The MC pre-preamp kit consists of a PCB, standoffs, the circuit parts and building instructions. This is the Boozhound Laboratories JFET Moving-Coil (MC) Pre-Preamp Kit. I highly recommend that anyone looking for a little iPod or computer amp give this one a try.ĭIY JFET MC Pre-Preamp Kit - 19 Sept 2015 KIT Low Voltage 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.

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.
