    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. Use a free photo hosting web sites like PostImage.com to host your image(s). Please give a PRICE for the item(s) you that you list here. 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 ..

    Place FOR SALE or WANTED audio related items in this STICKY thread Empty Tubes4HiFi closeout - custom amp

    Post by Roy Mottram Wed Sep 20, 2023 8:35 pm

    up for sale is my custom ampifier (VTA80) which uses my standard VTA70 driver board.
    Essentially a high-end version of the Dynaco ST70, but using expensive toroidal output and power transformers for super quality.
    This one is outfitted with four Mundorf silver-oil output caps.  Top photo shows an older version of the amp,
    this newer amp has a 5U4GT rectifier tube, center rear.   The blue tape in the photo is to protect the edges of the top plate
    during shipping, the amp is temporarily mounted to a stiff 2x4" lumber frame, the nice walnut wood cabinent is included and shipped separately.
    This amp was originally listed at $2000, now selling for less than actual parts cost - $800 (not including tubes - add $250 for a new set including four 6CA7 and three 6SN7, plus rectifier tube).

    Place FOR SALE or WANTED audio related items in this STICKY thread Empty Weber SS rectifier

    Post by Roy Mottram Sat Jan 06, 2024 1:00 am

    Weber SS rectifier kit $6 for one or $10 for two, plus $5 shipping.
    Same as sold by Weber (WS1) for $26 except you solder the diodes and limiter to the 8 pin socket and then put it into the copper top.

    Place FOR SALE or WANTED audio related items in this STICKY thread Empty Tubes4HiFi SP8 stereo preamp with phono

    Post by Roy Mottram Wed Feb 14, 2024 6:19 pm

    built 3 years ago and listed for $900 but never sold, so now it's $290 plus shipping (around $30-40 USA)
    Essentially brand new.  Not recommended for systems with high effiecency speakers, but fine with most others (tube phono sections can be slightly noisy).
    Uses two 12AX7 and two 12AU7 plus a 12X4 rectifier tube

    Post by ngoyette Tue Feb 20, 2024 1:56 pm

    Dynakit MK-III that is restored, in excellent shape and function

    I can send more pic's to you if interested.

    Unit test perfect, and the amplifier works great, no issues, sounds excellent and is extremely quiet.

    Transformers are all original
    The cage is the original

    The unit has the SDS power supply board incorporated inside the chassis, I kept the original quad-section capacitor in place to maintain the original look of the unit. The bias is rock solid.  Yellow sheet added.

    The driver board from the Triode store is also the modern equivalent

    Unit has all NEW 6550 Output tubes, new ECC82 (12AU7) and new GZ34

    Updated Speaker connections (4 and 8 ohm)
    Updated Gold plated RCA input jack

    Tubes included:

    Matched set of Svetlana 6550 Tubes with less than 10 hours (New)

    1 JJ GZ34 (New)
    1 JJ ECC82 (12AU7) (New)
    1 GE 12AU7

    $549
