I have decided to sell the SP12/PH12 kit that I built from Roy. If you have been reading the thread on the hum problem for this preamp, you'll know that this unit has a very similar hum problem to Ed. Read all about it here: http://dynacotubeaudio.forumotion.com/t675-vta-sp12-and-ph12-build-thread

I paid about $900 for my kit. It needs to have the PH12 reconnected and some other signal wires reconnected. All boards are populated 100%.

All the buyer needs to do is solve the hum problem. It will likely work well with the choke and other parts additions that were previously discussed on this thread.

I am asking $600 which Includes Shipping in the USA. Save $300 and with minimal additional funds if any, have yourself an amazing preamp with phono section.

Why am I doing this? I currently use a passive preamp, which is just a box with a selector switch and left and right independent stepped attenuators. That is all that is between my sources and my ST-70, and the sound is wonderful. I'm not sure why I wanted to mess with it to begin with other than that I wanted a project. Well, I had my project and I had my fun up until I plugged it in. Now I have put my energy into an automotive project that is much more conducive to my knowledge base than this kit. I don't have the experience or time to make this kit work, so it would be best sold to someone that does.

Hi all:
I have a lot of FM-3 parts lying around after doing 5 tuners. Mostly original stuff that might re-cycle so if anyone is looking for parts let me know. The list is too long to type with two fingers.

Check with Kevin at DynakitParts@aol.com He might be able to sell you just a bottom cover for the MKIII.

Hello,
I'm selling my st70 with a VTA upgrade board.
it has all options and is being sold with only the 3 12at7's no other tubes included my asking price is $700 + s/h and paypal fees.I got a pair of tektron kt66 mono blocks on the way that I need to make room for.

thanks you

For the cost of shipping I have 3 MKIII chassis, top and bottom no cover. They are all pretty worked over from corrosion but would make a great clean up with paint for a low budget MKIII project. I think 2 were factory built (riveted sockets) and one was a home built version. All have the dynaco driver board, sockets and various parts. NO Transformers except chokes. Parts missing as I needed them (No power cords for example).

These are for projects to be built, not for resale on ebay, so if you want one or more of these let me know. I reserve the right to give them to whom ever I feel like if multiple folks want them.

Again just for the cost of shipping.

I'm hoping someone out there in Dynaco-land has an old analog oscilloscope collecting dust that they wouldn't mind selling. My needs aren't great, I just want something with 2 channels that works to learn on with my amps and preamps. It would be my first oscope.
Thanks Rich

Time to clean house of some quads of power tubes and free up a little money....I have three quads available:

One matched quad of Electro Harmonix EL34's, cryogenically treated by CryoSet, burned in and matched for transconductance and current draw. Used no more than 200 hours, sound great, no issues, hold tight bias. These retail at $89.99 (remember they're cryo treated) Asking $60.00+shipping and Paypal fees. That's the price of a new quad, no cryo dip, no burn in.
I STILL HAVE THESE AS OF 4/10/12, PLEASE PM ME WITH OFFERS!!

Have you considered the reproduction boards from Dynakit Parts? They are drop-in replacements identical to the originals, but they are made from polyimide (not phenolic) and have heavier traces. Here's the link: http://www.dynakitparts.com/store/catalog.aspx?cid=11

Hi,

I'm new to this forum, and it seems like a great place to learn about all things Dynaco. I'm looking to see if someone is willing to part with a PAS 2 for a fair price (the one with the gold face)? In my "perfect world" it is in good shape cosmetically, but something I can restore.

I'm a relative noobie in the world of vintage HiFi, and any tips, hints suggests anyone has to offer will be greatly appreciated.

Thanks

btw, I'm not quite sure how it works here....should I expect a PM or will a reply be posted here?"

Thanks

I am looking for an assembled passive pre amp I dont need anything but attenuators to (no selector switch needed or wanted) I am wondering if the attenuator offered for installing on the st-70 or st-120 could be installed in a separate box for use with different power amps ,thx Scott
