Dynaco ST-70 totally restored vs Dynaco ST-70 Kit

Second Ponnie's take on things.Good luck,Bob

A dissenting opinion. I would go with Bob Latino's kit. The power transformer is beefed up over the original Dyna transformer, being a 5 amp job, the input board is the all triode Tube4Less board with individual bias for each tube (I prefer fixed bias to cathode bias). All the parts are new, many being American made. Basically, this addresses the weaknesses in the best selling amp of all time and makes this classic great for everyday use. I would also point out that all of the parts are available, most from multiple suppliers, so that should your Dyna break, now or in 20 years, there will be constant support for the amp.

i am considering a stereo 70 myself. i will only buy an original, stock stereo 70. if i want more "resolution", i'll buy another amp.

why take an orange and turn it into an apple, when you can buy an apple ?

Does Primaluna uses cheap parts compared to the Dynaco ST-70 Kit?

The Primaluna is made in china(cap omitted intentionally). That should answer your question.
