    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 ..

    OT - Solid-State Dynaco ST-120s

    Post by Peter W. on Thu Jun 29, 2017 10:07 am

    So as to make NO confusing statements - I am writing of SOLID-STATE ST120s made from the late 1960s through the demise of Dynaco.

    I snagged four (4) of these at Kutztown in May, all in some greater or lesser degree of non-function but all entirely restorable. My intent is to restore them to "full" TIP-Mod status, basic description here:

    There is more sometimes, depending on the vintage of the original iron. I match transistors between and within channels, and screen capacitors as well. output transistors are socketed. The covers are typically re-painted with black hammertone, and the plated bottoms cleaned to the extent possible. I also have one (1) ready to go at this time. Pictures available on request.

    These make excellent shop-amps, second-system amps and with the TIP-Mod are far more stable than OEM and no slouches at all in performance. Possibly a "summer" amp as when properly modified, they run fairly cool.

    For an additional $75, I will also do the upgraded self-resetting power-supply modification.

    Generally, I get about $125 + shipping - across a range from as little as $105 to as much as $250 depending on a) Cosmetics and b) additional mods as requested (and there are more than a few).

    Or one may purchase a rough carcass for $50 and up with only the power-transformer guaranteed, and do the mods directly. It is not rocket science and most mods may be purchased as drop-in items - boards, cap assemblies and such - albeit at some cost.

    McShane matched quad of Gold Lion KT-88 tubes - brand new, just arrived this week. I've decided to stick with what I have for a while longer. $200 shipped, payment via PayPal friends and family - you can check out Audiogon (vinyladdict) where I have 144 positive feedbacks with a 100% positive rating or eBay (vynyltap) where I have 1,930 feedbacks with a 100% positive rating for a feedback history. PM with any questions or concerns.

    Just to add:  When I was in the business, I worked on a lot of Dynaco Stereo 120s.  If correctly done, they in no way resemble their reputation as harsh-sounding solid state meanies.  I kept two of them when customers didn't want to pay the cost of repair.  In all fairness, one had shorted output and driver transistors and assorted associated parts, and would have been costly to fix; but the other only had an open Class A input transistor and was an inexpensive fix.  I worked on them in my spare time and both turned out splendidly.  I still have one, my brother the other and they both still function and sound fine.  At intervals the equipment in my system gets a periodic going-over on the bench.  When my tube amps (modified and upgraded from Dynaco Mark IIs) undergo this process, the Stereo 120 substitutes.

    Some technicians would repair the Dynaco Stereo 120 with cheap output transistors...nonselected 2N3055s that they bought for less than a dollar.  "Floor sweepings," we used to call them.  Dynaco used 2N3055s in their early production (and the transistors were often marked, "2N3055") but they were selected and matched by the factory.  No wonder the ones fixed with the cheapies didn't sound right, or blew up!

    Harmon Kardon A300 ready to go

    Post by Dave_in_Va on Fri Nov 24, 2017 10:04 pm

    "I purchased this from an H-K A300 enthusiast last Dec. The amp has been totally recapped and is ready to go. When I got it, it had mostly all orig. tubes. I replaced the H-K 7408 tubes with new in the box WW II Ken Rad 6V6GC (pre-GE). I think I may have also replaced a few of the pre-amp tubes with cork sniffer stuff.

    So, I used this for streaming on Roku coming out of my TV (through a Music Fidelity DAC). Worked fine. Then I remembered I had a solid state home theater amp that had a optical audio input so I swapped the HK out. The SS Yamaha is fine for TV type stuff. I use my VTA stuff (with real cork sniffer tubes) for serious music listening.

    Anyway...$531 which is exactly what I paid for it except it still has about $150 extra worth of my tubes installed.

    It has the (nicely painted a industrial grey) cover.

    Great for a second system, etc.


    PS If you want pics etc., and you're serious, please email me"

    Tubes for trade. I've got some I don't need any more and I'd like to trade them for some I can use.

    2) Sovtek 12AX7WC
    2) Doge 12AX7B
    2) Pro/Comm (Tungsram) 12AX7
    2) 7025 one is labeled Pro/Comm and the other looks like a USA GE

    most of these should be worth around 8 bucks

    I'd like to trade for some 6922s and a 12AT7

    I also have original PC5 and PC6 (PAS linestage and phono board), 2 of each, $5/board.
    Brass PAS 2 face plate ok shape $10

    Not Dynaco - but Related and Free to a Good Home

    Post by Peter W. on Mon Feb 19, 2018 2:06 pm

    First: The conditions:

    Must pick up in Melrose Park, PA. I WILL NOT SHIP.

    Must pick on-or-before this coming Saturday.

    I am not available this coming Wednesday.

    Must take all-or-nothing. No cherry-picking (though there are no pits).

    I do not want to see them on eBay the moment after pick-up. I am not stating that this cannot happen, but I would prefer they go to a user rather than an exploiter.

    One working Fisher tube tuner - apparently with the SS MPX chip on board as I remember, it is an FM200B and with the wood case.

    One working (black) Nikko integrated amplifier. Could be an NA 690 as it has meters. Good condition.

    One working Sony dual-cassette deck. Black

    One working no-name 5-disc CD/DVD changer with remote and cable.

    I am culling the herd, and I have not-much-use for Pacific-Rim equipment, nor will I be ever likely to use the Fisher tuner. So, I am passing them on for exactly what I paid for them.

    First person-by-date-stamp-on-email gets it. Remove spaces and add appropriate symbols.

    For sale - vintage Dyna ST 70 - SOLD

    Post by WLT on Fri Mar 09, 2018 12:16 am

    SOLD - For sale is a vintage Dyna ST 70 in good condition. It has some corrosion and haze on the plating so it will never be a show piece. From the photos you can see it is almost completely stock original. No extra holes or bent chassis parts. Although not shown in the photos it will come with a used set of Sovtec EL34s, an American 5AR4 and 7199s. It worked fine with these so the transformers are good. It should be gone thru properly as the caps look to be original.
    I am selling this for an organization I volunteer at. They have set the price at $480 plus shipping. Email me at if you or someone you know is interested. It will only be available here for about two weeks.
