Hello from Ottawa.

I have acquired a new, from Radial Engineering, Dynaco ST 70 Series III tube power amp.

Looking to see if anyone online has any experience with this amp.

:)

Radial Engineering makes Guitar products, how did you get a "New Dynaco ST 70" from them......?

Never mind, I found your other post that had an actual link in it.

Seems they own Hafler and Dynaco too.

It's been a wonderful amplifier. I've had it for about 6 weeks.

I love the build, I love the look. I love the size. The sound has been great (my best amp to date overall for my living room).
It is now being driven by a PS audio Stellar Gain Cel DAC preamp. Good synergy between the two.

Unfortunately the Dynaco amp gave up the ghost this past Tuesday. I've emailed Radial and Dynaco to see what the next steps will be to get it diagnosed and repaired. The high bias lights are out. Maybe just a fuse? or....I turned it off. Hopefully it is something simple.

Stay tuned!

Make sure to get the schematic as it apparently can be obtained from the retailer or distributor! That way it can be fixed by anyone easily in the future.
