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

    Post by Bob Latino on Mon Apr 27, 2009 3:28 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 10:51 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.

    Wanted ST 70 and ST 35 parts

    Post by cc43fan on Sun Oct 13, 2013 6:39 am

    I'm looking for a couple of things..
    First, an ST 70 cage and bottom cover.

    Second, an power transformer for an ST 35 (PA774).

    I know that these items can be purchased new, but I was hoping to save a few dollars by buying used. I can offer trades if that's option as well....tubes, tube testers, caps, resistors, etc.

    Drop me a line if you can help @ new2pilot at

    Thanks for looking,

    Analog Man

    Just below the last post in a thread it says "Post replyPost new". For some reason the forum software does not leave a space between the "Post reply" and the "Post new" and runs the words together. If you hover the mouse over Post reply and then over Post new, you get two different hyperlinks in the bottom of the window. The "Post new" puts your post into the main basket of the forum as a new post while the "Post reply" puts your post in THIS thread as a new item for sale. The reason we use this thread is that we don't want forum users to have to scan over for sale items in the main body or "basket" of the forum.

    Others have done this and the confusion is understandable ...

    Vincent Pre-amp

    Post by Brap on Thu Feb 13, 2014 1:43 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.

    I have upgraded my ST-70  to the new low gain VTA board; so I'm posting my gently used high gain board (built in 2009) here to see if any of you Dynaco-heads might want or need it.   This is the one that takes the 12at7 tubes and I will include three JJ 12at7's with the sale or trade. It has the standard cap configuration. There is nothing wrong with this board or its components.   I would like to get $100 for the 3 tubes and the board but I am also willing to trade for KT-66 power tubes, 12au7 driver tubes, 12bh7 drivers, 6cg7 drivers, ADS speakers (710 or 810) or maybe some vinyl, depending on what you have (Japanese pressings, Jazz, etc).  Questions? Just shoot me a reply or PM.  Cheers.

    WTB . . . Tube PreAmp (phono stage)

    Post by PopaTopSmith on Thu Feb 20, 2014 5:33 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 . . .

    Speaker Cable magic, anyone?

    Post by deepee99 on Fri Feb 21, 2014 9:20 am

    I have a six-month-old 8-foot pair of Reality Cables' renowned speaker cables for sale. Website here:
    I have since gone to bi-wiring and no longer need these; first $200 takes them, they were over $300 new. Spades on all ends. Shipping included in price.
    PM if interested; these are definitely a step up from Monster Cables and the hyped stuff from AudioQuest.

    I have two ST-35's for sale, I really don't know what they're worth, but I know they both work!  I bought them from the original owner and they are clean, undamaged.  Any offers?  I'm motivated to sell them and know that this is the place they'll find a home that will love them.  If interested, please contact and I'll arrange to give you all the pics and info you would like.  I am in the S.F. bay area (Livermore, home of the Lawrence Livermore National Laboratory.)  FYI, the amps were built by a Electronics Tech at the Lab, a good friend and a top notch technician.
    I guess I can't do that :-(
    Okay, if anyone is interested call me at 925-337-5516

    new phono preamps for sale

    Post by tubes4hifi on Thu Apr 03, 2014 7:58 pm

    I've got some new phono preamps for sale that aren't part of my regular offerings.
    One of them I first did 2-3 years ago, the PH9, uses four 12AX7 in a CCDA configuration and sounds excellent.
    The other one is the PH17, I have two of these, brand new, uses four 12AX7 in the same circuit configuration as the PH16.
    Doesn't sound as good as the PH16 though, otherwise fine, use a good set of 12AX7s.
    I can sell you stuffed tested PCBs, or I can put them in new chassis to look identical to a brand new PH16,
    or for the budget minded I have an old PAT4 chassis that I can put one in and have a brand new custom faceplate made.
    These all include the power supply section, just need to add one combo 200/12v power transformer about $40.
    The PH9 board is $250 without tubes.   The PH17s are $250 each without tubes.   Photos and more info available upon request.
    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.

    Photos below, top one is PH9 board, bottom one is PH17 in a 16" chassis

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

    Post by j beede on Sun Apr 27, 2014 10:47 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.
