    Just like with other tubes, specific rectifier tubes may have some equivalent replacements but they are not universally interchangeable. Wouldn't be wise to learn that the hard way... BOOM!

    Randy

    It uses a 6X4 rectifier tube and good NOS ones are usually found under $20. Really aren't that many options and the NOS one he provides should be fine.

    Re: Audio Mirror Pre-amp

    Thanks Jack,

    Vladimir does take the sound quality first approach so I have no doubt what he provides will be good. I always like to have at least one backup set of tubes ...

    I know it is not an expensive pre-amp, but I am really looking forward to getting it in my system. It is supposed to be a very good sounding basic DHT pre-amp (sounds exactly like what Joe was looking for a little bit ago )... Too bad Vlad is having issues getting enough parts to build them in quantity now .

    Re: Audio Mirror Pre-amp

    A good read on the 6dj8-6922-7308-6n1p family of tubes can be found online under "Joe's Tube Lore".
    As for the rectifier tube, in some pieces of gear and in some systems the rectifier tube can alter the sound more than the rolling of the other tubes.
    The D.C. is VERY important.
    However if it is a 6X4 then you need to stay with that numbered tube as there are no (IMO) good substitutions just different manufacturers.
    EZ90's, (6X4's), such as Amperex and or Mullard are usually at the top of the pile although some of the military (W's) are also good.
    Just have fun with it and enjoy.
    My System:
    A trusty old Pioneer PD-65 as a Transport, A MicroRendui, a Merrill Heirloom T.T. as sources. A Lampizator DAC to PAD Cables to a SP-14 Tubed PreAmp, Coincident Frankenstein 300B monoblocks, & or Valvet E-2, Fusion speaker cables, AudioKinesis Zephryn 46 Speakers. pair Rythmik F-12 subs, EP2050, DCCA Furutech and Kaplan Power cables, APC power conditioner, Two dedicated 20Amp power lines. DIY corner traps and Acoustic Geometry Curves for room treatment.

    Vladimir let me know that my pre-amp should be finished by tomorrow! I am so looking forward to listening to this little DHT preamplifier.
