We are pleased to announce that we have released our ultimate ST-70 upgrade kit, our Dyna-70.
This is 'hardcore' upgrade, eliminating the old driver circuit as well as the old power supply, replacing it with a modern 6SN7 based driver circuit and an all solid-state power supply!
For all the details, please visit our web page here, http://www.erhard-audio.com/DYNA-70.html
