I did a search on HiFi Shark and found this link for an eBay listing

Greetings & Welcome to AC  :thumb:  Likely your only source will be the used market at this point. Good luck with the hunt, it's a great little amp.

I just bought one on the used market in February for around 1500
It's a fabulous little brute of an amp.  Powering some Flacon ls3/5a's with it for now.
They don't come up often but keep an eye out or set up an alert and one will pop up at some point.

I have a Dynaco 70 that has the latest ultravalve upgrade. A real nice amp with nearly new tubes. I would take $1000 plus shipping. I live in Dallas Tx.

thats the guy selling it for double, triple--hes had it on ebay for years. obviously hes not interested in selling. he had it at $3k for years and just upped the price.

here are some sales figures

these are not true sales figues, as the final asking price is published but the sale price is not.

check hifi shiark religiously; youll find one.

I have an Utimate 70 from AVA in daily use, not far behind the Ultravalve in performance I guess…

If you simply can't find a used Ultravalve, ( the guy who wants $3500 is simply a non starter at that price  :scratch:) there are many new ST70 build options out there. Too many to list in fact.

We still have the bare mother board and  the build manual available for the Ultravalve version.  Requires an original Dyna ST-70 chassis with good transformers.

Plans free, PC-1104 mother board $50.00.

But wait until you hear our new NP1 amplifier.

I've looked at many ST 70 options and a very good one is Bryan Miller at https://milleraudiollc.com/

I've spoken with Bryan and he is open to custom work as to different parts, colors and he has a different chassis available as well. He is retired from a career in aerospace and works with his son Spencer.

I suspect it's a typo, and he means the new NP1 amp?    :dunno:
