    Calling All "Vintage" Integrated/Receiver Owners

    I just got my Marantz 2252B back from surgery.  Cosmetically, it looked like it was salvaged from hurricane Katrina.  It had loose knobs and the selector swithc had one side of the knurled shaft missing so that a know wouldn't even stay on. All new electrolytics and speaker relay replaced.  The...

    Vintage receivers (Pioneer, Luxman, Marantz, Sansui)?

    I just bought a Marantz 2252b for 100 bucks off of craigslist.  10 dollars for some contact cleaner and my high end stuff sound thin compared to this beauty

    sharing worst experience in audio-gd! Be careful everyone..

    How does it sound without eq? Although the dac is doing the decoding, you pc is still altering the tone if you are using the eq.  Are you using USB, or spidf?  My setup disables the eq when using spidf, but usb treats it like a soundcard and eq options are available. It very well could be your...

    List of entry level TUBE amps + mod for less than $300

    I would go with the Darkvoice 336se for several reasons over the Little Dot.  The Darkvoice 336se, is mostly point to point wired, which lends itself to easier modding and repair down the road.  Also the tubes used a much easier to come by and much cheaper for NOS tubes.

    5670 W396a 2C51 6N3P tube thread

    As far as these variants, I have tried a bunch and this is the one instance were the Chinese 6n3t (taller version) is better than the NOS stuff out there. All of the NOS sound dull and boomy

    DV 336SE hum-Fitz mod?

    One more thing. Why is one leg of the heaters going to ground? I would.expect that with DC heaters but not AC.

    Grado SR80i vs SR60i ? Does it really matters ?

    I have been told by a reputable source that the only difference is better gauge wire in the headphone cable. I have a/b'd them extensively and can not hear a noticeable difference that I could identify which I was listening to.

    Darkvoice 336 + 336i Tuberolling [ tubes ]

    I recommend that before spenging alot on boutique NOS tubes, get some sylvania 6sn7s as they seem to have the best chance is not humming. I have noisy tubes in about every brand that are noisy except the sylvanias. I am 5 for 5 with those and 2 for 3 with tung sols

    Commentary on Tube Rolling and Misunderstanding of the Science

    I always get a little frustrated reading reviews and suggestion on NOS tubes based on limited experience with tubes. It first needs to be understood that there are huge variances in tolerance, even with the same brand.  This applies to all tube new, used, and NOS.  The reality, is that most...

    DV 336SE hum-Fitz mod?

    If the noise is in fact from the heaters, I will try to DC elevate the heaters. This involves using 2 resistors and a cap from the B+ DC rectified power supply to the center tap of the heaters. I should have mine next week.  By installing a cathode bypass cap, you are modifying the gain and...

    Just need a little help.

    Yes, you will have more flexability with the Asus DAC, as you can use the EQ. The Burr Brown DAC on the Asus is pretty decent.
