It works together with the AC negative feedback from the output of the audio transformer to the cathode of EF86. These improvements enhance the flatness of the frequency response and …

Sep 6, 2014 · Mullard Single-Ended (SE) EL84 Tube Amplifier Schematic. This is the classic single-ended EL84 schematic from Mullard. The input stage uses a EF86 to drive a Mullard …

May 7, 2023 · Just as a point of reference, My small SEPs use an EF86 in pentode mode to drive a pentode-mode 6V6 with a 5K load. Global feedback is about 19dB, and sensitivity is 0.9v …

Mar 14, 2020 · I highly recommend trying a CFB SE amplifier. It retains a lot of SE magic (immediacy and intimacy), while having clean, punchy bass and lacks that typical high level …

Sep 6, 2014 · Single-Ended (SE) EL34 Tube Amplifier Schematic with EF86 input stage. The power supply is solid state. The filament supply is regulated at 6.3V using a LT1085 voltage …

Aug 20, 2021 · EF86 – 300B XLS SE Amplifier build Here is a very nice build from Dan Kercher on his contraption of the 300B amplifier with auto bias. The driver is an EF86 with SiC diode …

The amplifier, which is operated from AC mains, uses three Mullard valves: an EF86, an EL84 and an EZ80. The comparatively high sensitivity of the amplifier (100 mV for 3 W) permits the …

Jan 23, 2011 · The pre-amp has an EF86 slot in V1 with Merlin's Triode/Pentode Morph control (labelled "Mojo" on top, in case it doesn't work and I have to think of something else to change …

The EF86 is the standard early stage audio pre-amplifier valve. This exhibit was made by Mullard in Great Britain. Mullard designed the EF86 and it took over the frond end stage of audio …

Low noise pentode intended for use as R.C. couPled A.F. EF86 voltage amplifier, particularly in the early stages of high-gain audio amplifiers, microphone pre-amplifiers and magnetic tape …
