2022年7月13日 · Maybe you should explore a line stage with much lower gain or a tube buffer stage. I have a version of the Blue Velvet Preamp using 12SN7 tubes (gain is 6 or less). I used zeners and a mosfet for the regulated supply instead of the vacuum tube regulators. I use a DAC for an input and drive amplifiers that need 2 volts or less for full power.

2017年5月22日 · Good point. I am uncertain how I am going to use this tube amp. I had contemplated using it with both guitar and hifi application. My guitar pedal board is a mess currently but I am planning to make it a stereo setup eventually with an amp sim / preamp pedal followed by a stereo reverb pedal.

2021年12月13日 · Hi Forum, I decided to make a tube only RIAA phono stage and make a nice over the top PCB for it. The design is a bit based on the Luxman EQ 500 with less bell and whistles, but in basic form the same thing. A friend of mine wanted to tag along. We ordered 3 main boards, one to prototype on and...

2024年10月24日 · Want a top sounding tube preamp. Loose the hv reg,and put a high xl low ohm choke there.make sure its high quality,high b strip wound double c core best. You will have dynamics, fluidity,harmonic resolution,all the good stuff we audio nuts love. Probably get ride of the silicon in the amp. Keep it simple,use best quality parts.good luck.

2009年3月25日 · It's quite well documented all over this forum and is flexible to tube choice, you can use 9-pin mini's or octals (John Broskie (Tubecad) sells both flavor boards), and you can select tubes to get the gain you need.

2012年6月22日 · RIAA Preamp Build (Part 1) Well, someone asked me to design a low-noise stereo preamp for RIAA, (record phono input Equalization), so Challenge Accepted! I made a preliminary design effort using a Mu-Follower type layout for dead-quiet PSRR and low noise, and also chose a low-voltage...

2024年12月1日 · Posting the schematic of my tube preamp: Sounds ok but when breaks up, the overdrive is too thick. Swapped the cathode bypass caps from 22uf to 2.2uf but can't notice any difference. Swapped the cathode resistors from 820 to 2k4 (should be towards less gain and cold/ asymmetrical clipping)...

2017年12月10日 · Hi. I need a balanced diy tube preamp for my soundsystem. 2 channel stereo line XLR in/output. "Audiophile" grade. Whatever that is lol. It should sound just very good. No sloppy bass, etc. It should produce deep clean precise bass and have a warm like sound in mids/highs. I found out about...
