Inside
This project is based on Erno Borbely’s EB-602/210 single-ended pure Class A amplifier and is capable of driving headphones between 32 and 600Ω. It consists of two identical but separate amps laid out on the same PCB. The schematic is the same as Erno’s extremely popular hybrid tube/MOSFET line amp, published in Glass Audio 1/98. However, the dual triode at the input is replaced by a dual JFET (SK389). This article was originally published in audioXpress, July 2004.
DIY Hi-Fi: Class a Hybrid Headphone Amp: FORWARD::::::: This project was born out of a couple things. One was a need for an amp to drive some higher impedance headphones I had just bought. (The Grado SR125i headphone is great, by the way.) Also, since I have began my freshman year at Bosto…

Bruce Heran outlines the design and construction of monoblock Push-Pull EL84 (6BQ5) valve amplifiers. The Mini Block tube amplifiers use a 5751 in the driver position and the EL84 output circuit is biased into Class-A, ultra-linear operation. Output power is 5.8W @ 2% (0.25% @ 1W) and response is 10 Hz to 44 kHz +/- 0.2dB.

by Alex Cavalli This project grew from several conversations that I had with John Broskie of the TubeCAD Journal. I was looking for a good headphone amp and John and I discussed some of the advantages and disadvantages of several of his published circuits. I must say that for someone who creates so much good…
