    Place FOR SALE or WANTED audio related items in this STICKY thread

    Post by Bob Latino on Mon Apr 27, 2009 4:28 pm

    Here in this sticky thread is where you may post any older personal audio related items you may have for sale or you may want. You may NOT advertise any NEW audio related items that you may sell on an ongoing basis on Ebay, Audiogon or any web site. This thread is not to be used for commercial sellers of audio gear. Commercial sellers may, however, advertise any personal used audio gear that they may have. It is helpful if you post a photo of the item. This forum is supposed to be able to host a photo but I have trouble making it work so you will have to host the photo yourself on Photobucket or one of the other free photo hosting web sites. Do not post any ITEMS FOR SALE in the main "basket" of the Dynaco Tube Audio Forum or I will remove the post.

    NOTE 1 - If you want to post a FOR SALE item in this thread please hit the "Post Reply" button to add your item IN THIS THREAD. Do not use the "Post New" button. If you hit the "Post New" button, your for sale item will appear in the main body of the forum instead of this thread.

    NOTE 2 - After your item has been sold please EDIT your post and mark the item as "SOLD" and I will remove your item from this thread.

    Also - After about 1 year I will remove your post whether it has been sold or not ..

    AMB remote control PREAMP PROJECT

    Post by tubes4hifi on Tue Jun 11, 2013 11:51 pm

    someone emailed me about this within the last week or two, but now I can't find the email.
    I think they wanted to use it in conjunction with an SP14 preamp for the ultimate $10,000 value preamp (for around $2500).
    This is a great project preamp for someone with electronics experience.
    About $750 invested in this remote controlled, microprocessor controlled, LCD display preamp,
    with mil-spec mini-relays used for signal inputs, outputs, and volume/balance attenuation.
    Custom preamp chassis and power supplies.  
    Price reduced to $250!!   Check it out here:
    Several photos on link, only showing the front panel here to save space.
    Please check out the link, read in full, any questions via PM or email please.
    Fully assembled, tested, working, but needs some more connections, and a suitable programmable remote control.   Includes full documentation.

    YES, still for sale as of January 14, 2015 . . . . this is a super deal !!!

    Vincent Pre-amp

    Post by Brap on Thu Feb 13, 2014 3:43 pm

    Hey there group. If anyone is interested, I have a Vincent Phono Pre-amp PHO8 for sale. This has less than 20 hours on it. Upgraded and purchased a Parasound P-5 and use that exclusively now. If any of you run Vinyl and have the attenuator option, this is a nice Pre-amp for the price. Two separate units, one being the power supply. Check it out on line and it's reviews. Willing to part for $350.00.

    WTB . . . Tube PreAmp (phono stage)

    Post by PopaTopSmith on Thu Feb 20, 2014 7:33 am


    I've recently acquired my first pieces of tube equipment . . . ST-70 - PAS 2 - FM1 . . . So far, I'm enjoying the hobby but I'm not satisfied with the PAS 2 sound, especially the phono stage.  I love the sound of the ST-70 playing CD's on my California Audio Labs player, but listening to vinyl on my Technics SL-1200mk2 has been disappointing - not nearly as enjoyable as the records sounded on my SS Sansui 9090.  I think I've decided rather than put more money into the PAS 2 via upgrades/mods, I'm going to look around for a good, used phono stage preamp.  If anyone has one for sale, please let me know via email . . .

    I've got some a phono preamp for sale that isn't part of my regular offerings.
    This is a PH9, uses four 12AX7 in a CCDA configuration and sounds excellent.
    I can sell you stuffed tested PCB, or I can put it in new chassis to look identical to a brand new PH16,
    The PH9 board is $250 without tubes.   PAT4 chassis with new custom faceplate $160.   New PH16 style chassis with new front and rear machined/engraved panels $250.
    Please rely via email or PM, not in this for sale thread, thanks.

    NOS Waldom 23 step, 2-pole rotary switch $10 + s&h

    Post by j beede on Sun Apr 27, 2014 11:47 am

    This is a large 23-step, 2-pole (stereo) rotary switch, NOS. I bought several of these but have never used them. Waldom PA-4003. The switch is quite large with STRONG detents, but might make a fun project for someone who has a large assortment of resistors and a PAS 2/3/3X with room for a stepped attenuator. Not sure if 23 steps is enough for a proper volume control. $10 each or $15 for two. Please add $3 flat rate for USPS shipping.

    Re: Place FOR SALE or WANTED audio related items in this STICKY thread

    Post by daveshel on Tue Oct 21, 2014 4:26 pm

    I've got some tubes to sell or preferably trade. These came out of my ST-70 that I bouglt on the evil auction site 8-9 years ago. I sent it off to Van Alstine for his mod and he put in all new tubes. I have since sold the ST-70 and now have an ST-35 in which I'd like to try some tube rolling.

    I have a pair of 7199s. One is branded Sylvania (USA) and the other us Tung-Sol with a faded and sloppy label. I'd trade these for some 7247s.

    I also have a quad of EL34s. One has the Mullard brand and the other 3 are Tesla. All have faded labels and 2 of the Teslas have discolored bases. I'd trade these for the right quad of EL84s.

    Elsewise, I'm open to suggestions/discussion as these aren't doing me any good sitting in a drawer.

    I picked up a NOS Mullard to try in the center position of my VTA ST-70. I didn't notice much if any difference between it and my RCA. I paid $40. Tried it for about an hour.
    Anyone else want to try it for cheap?
    $30 postpaid including Paypal (Continental USA).
    (Comes in the orig. blue Mullard box.)
    I'm in Va.

    VTA ST-70 with new high gain board...SOLD SOLD SOLD SOLD SOLD SOLD SOLD SOLD

    Post by deluxmon on Thu Jan 15, 2015 11:22 am

    I am selling my beloved VTA ST-70 as I am going to embark on a ST-120 journey now ...So, my beautiful sounding ST-70 is offered here to you all. It is about 4 years old and was originally wired-up by Roy. It has a custom aluminum faceplate also made by Roy that allows you to check the tube bias without cage removal - which is a pretty nice upgrade......I bought it from the original owner and then had Roy make some additional modifications, most notably the stepped attenuator and the upgraded speaker posts available from Bob's site.  The attenuator allows you to run your CD player or Ipod directly into the amp without needing a pre-amp.

    About 1 year ago I changed out the PCB and it now sports the a new high-gain board that I bought in kit form from Bob.  I had it assembled by Mr. William Eccher a Hickok Tube Tester guru here in Denver.  Presumably you already know all about these amps so I won't do too much preaching to the choir about is an awesome amp!  And a tube rollers dream.  The cage cover is black in color not brown, like the originals. The Stainless Steel Fan unit is not included in this offer.

    I will include a NOS/ Unused Quad of Realistic brand (Chinese made?) EL34 power tubes from the 80's (purchased new by my Dad), a Second NOS / Unused Quad of Russian 6n3c-E (6L6GC equivalent) power tubes,  8 - 12AU7 driver tubes (all  strong), (1) - NOS Mullard /Hammond GZ34/5AR4 Rectifier tube (not the GZ37 shown in pictures) and (2) 5814A tubes that sound awesome as driver tubes in the center position. I've had it set up to accommodate either 8 or 16 Ohm speakers, but as you know it will also work with 4 Ohm speakers with a minor modification.

    $825 shipped to the lower 48 in two double boxes. One box for the unit and one for the tubes and cage.

    PM me any questions....

    For sale we have the prototype  of our newest phono preamp, the PH20. This is an enhanced, fully balanced version of the excellent PH16. It has the same FET/triode cascode front end for high gain with low noise, but in a balanced configuration with constant current sources, followed by a differential amp with a current sink for perfect linearity, then a symmetrical output buffer stage with super low 150 ohm output impedance! RIAA EQ is split between the first and second stages just like the PH16, giving flat response from 20Hz to 50KHz. The input impedance is 47K ohms, suitable for MM cartridges. There is no hum, and very little tube hiss, the tubes are low noise selected E88CC's.   Asking $800, which is what we have invested with materials and labor.
