    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 ..

    Bob

    Place FOR SALE or WANTED audio related items in this STICKY thread Empty NOS Mullard xf3 EL 34 quad for VTA ST 70

    Post by Dave_in_Va Tue Oct 01, 2019 2:18 pm

    {Edit: 02/18/21 Still got 'em. I installed a quad of these in my VTA ST 70 and they sound great. Couldn't tell the difference between these and the previous xf2 set.}

    Made by Mullard Blackburn UK. Labeled Amperex. I think the xf3 would indicate about 1974.

    I'm not a tube dealer. I bought a batch of these so I could make sure I had Mullards for my VTA ST 70 until the lights go out. Of course, I now have too many.

    These are about the highest quality tubes you can get for an ST 70. I read that these are 10,000 hour tubes but I read that on the internet soooo...

    (The boxes are a bit worn with one missing the top flap.)

    If you have an older Dynaco these should be fine. For reference I indicated the current draw on each tube in case you want to use these in a Marshall guitar amp or something. They are fairly well matched. I matched them up using a four can Weber Bias Rite with the tubes in a Vox AC 100.

    The price including priority mail in the USA is $415.

    Sorry about the washed out pics. The sunlight was very bright. The last pic was supposed to show the Mullard "holes" in the guide pins.

    (I also have a couple of matched pairs.)

    Place FOR SALE or WANTED audio related items in this STICKY thread Empty For Sale: VTA 120 - SOLD

    Post by corndog71 Mon Apr 19, 2021 1:29 pm

    I purchased this VTA 120 kit back in 2014.  It was originally used in a custom enclosure but has been restored to a new stainless steel chassis.  Speaker outputs wired for 8 Ohms.  Includes assembly and operation manual.

    Modifications from the stock kit include a 3-wire power cord which grounds the chassis and coupling caps are Solen fast caps.  1N4007 diodes have been added to the rectifier socket to protect the 5AR4 tube.

    Price is $1000 for the amp. (EDIT: Amp has been sold)

    I can also ship a new set of tubes for an additional $200.
    Matched set of TungSol 6550 from Jim McShane
    JJ GZ34 and 3x ECC82 (12AU7)

    Will only ship to continental US via fedex.

    PayPal for payment.  

    If interested please send PM for more details.
