    Decware SE34I.5 - Analog Discovery 2 test results for various power tubes

    That is ok BmWr. An easy way to test is to run a signal into one channel and measure the output voltage on the other channel with a scope, maybe even a digital voltmeter if it is accurate. --------------------- Concerns, R channel and L channel: What one usually will find is that above and...

    Decware SE34I.5 - Analog Discovery 2 test results for various power tubes

    And channel separation at low, medium, and high frequency? Just curious as this parameter is quite important. Thanks, all the best. joe

    Decware SE34I.5 - Analog Discovery 2 test results for various power tubes

    Thank you very much BmWr for your measurements. I was wondering if you would test and post the channel separation at some low, midrange 1khz, and especially higher frequencies, say 5khz, 10khz, 20khz? I am concerned with 2% plus Harmonic Distortion (HD) figure at 1 watt output. I can only...

    SME iii tone arm tracking

    Thanks Flavio. Much appreciated. I have owned the SME iii, Accutex 320 STR brick, STD TT for decades, but have not used it for a while and at 76, sadly, my memory has been failing. (My advice is to avoid getting old. :yikes: ) Another question I should have asked. How much tracking force do...

    SME iii tone arm tracking

    It has been a while since I used my STD turntable with SME iii tone arm and I have forgotten how to set tracking. After balancing the arm, I am suppose to slide a weight forward. How much does that add to tracking in grams? The knob I turn is scaled as 0, .25, .5. .75 etc. How much am I...

    Worth an upgrade to the new Schiit Mimir?

    Although just the dac, I have dimension in spades. If it sounds forward, could the Forkbeard be altering the musical signal after the dac? keep on truckin joe

    Worth an upgrade to the new Schiit Mimir?

    I agree, spot on except I have more depth, probably speakers or speaker placement. Crazy good. cheers pos

    Worth an upgrade to the new Schiit Mimir?

    Hi All, Updated post 4-18-26. Received the basic Mimir dac. No Forkbeard module, no preamplifier, just the dac. Cost was $299 plus tax and shipping. Looks great, simple to use. Separate external power transformer supplied for linear power supply, just plug in, or use the USB for power...

    What do you think are the best current production vacuum tubes?

    For me, after 45 years of listening testing as well as measurements, it is clear. For output tubes, I definitely prefer the reissue Mullard KT88 with cathode bias. Extremely transparent, natural sounding. I do run my output tubes rather easy, 440 p-k idle voltage, 29 watt plate dissipation...

    Russian new production Mullard KT88s are kind of OK

    Checking again I see you are not using ax7s and at7 types, which have a poor figure of merit. Yes, the OPT is the main problem. I am not certain why you need GNF unless THD problem and/or lower bass bloats. As an experiment, have you tried no GNF and see how it sounds and the waveform looks...

    Russian new production Mullard KT88s are kind of OK

    Thank you for your comments and review Kward. I love that you made several measurements and asked us to help. If I may, I would like to addressed some points that will help you and the general public/newbies. The small oscillation you measured has no meaning in reference to quality of the...
