Will Vincent has rebuilt hundreds of these legendary Dynaco amplifiers over the years (over 400 by his latest count). This amplifier uses a quad of reissue Mullard EL-34 tubes that have been "matched". It is the original design (7199 input tubes) with some of the best components (Infini-caps), oil and paper caps, 1% resistors, all new filters and American made tube sockets. The RCA single-ended inputs and 5-way speaker terminals are also American-made. And yes, Virginia, of course this still has the original cloth-lead transformers!It is also fitted with a IEC A/C connector so you can use high grade power cords. This particular ST-70 uses the "Star" grounding circuit for ultra quite service. The large meter is for quick Biasing and Monitoring at all times and takes less than a minute to Bias this amp. Last but not least, it will accommodate many different out-put tubes (KT-77 ,KT-66 ,EL34 ,6L6GC , 5881) because of a modified Bias circuit. A beautiful color (Tiffany Blue?) with a creme colored base, it looks at home in a more playful household. Personally, I still believe that the Dynaco ST-70 has a place in all audiophile systems. I've owned 5 of them in the last 20 years. I will run them as reference amps, backup amps, have-some-fun-with-vintage-audio amps, etc. Unlike so much other sonic drek out there for 10x the price, these workhorse amps have truly earned their nodding approval from those in the know. A solid thousand bucks takes it. I paid a little over $1200 3 years ago from Will. The Dynaco ST-70: Live it, Love it, Listen to it. :)
