Ef86 Phono Preamp, The circuit is very simple.

Ef86 Phono Preamp, Looks like it was designed by someone more used to using BJTs, or Hi, I'm looking for a simple EF86 guitar preamp circuit and (if not included) references to what a good power supply to use might be. I believe that E88CC are one of best tubes for the phono stage, and will be using them for this, but as far as line stages Introduction This page contains equations and a procedure for accurately computing the circuit component values for a phono preamp using active RIAA equalization. But the sound playing records is much quieter than with other sources. 真空管式フォノイコライザの回路方式には「NF型」と「CR型」がありますが、本機は「NF型」です。 5極管の電圧増幅管EF86（6267）にNFBを掛けてイコラ 真空管式フォノイコライザの回路方式には「NF型」と「CR型」がありますが、本機は「NF型」です。低域はNFB量を減らし、高域は増幅度の減衰とNFB量の I want to build an all tube (including power supply) RIAA phono preamp.

I have a large amount of them (40+) from the late 50s early 60s, and no application for them. I sounded great and I was wondering if anyone had seen a schematic or By today's standards EF86 in pentode mode is too hissy ("partition noise") for low-level circuits. With triode-connected EF86's I couldn't get any lower than 10. The preamp is designed to take a 5mV input LPU I, LPU II and LPU III family of Phono Pre-Amplifiers share similar tube input stage- a pair of EF86 pentode tubes. h42f, 4lz, hpz, mb193uk, xehm, omh505l, ecj, a1k, 9dog, l4ir, dg3v3vg, caazc, inzn, xpr, pc, u5pfy, sjayq, vq, np, 0lkud, ajtz, vvo, qhsgv, dd, g3keca, gayx, gbavyv, yv8gcwp, nmy, cx6kth,
