Dynaco ST-70 tube amp, 35 watt.
The most popular tube amp ever built, a classic. The poor man's McIntosh (!).
This one has been restored with new power supply, using german hi quality F&T caps. The input board has been replaced with a new one, coupling caps upgraded to AudioCap Theta, resistors upgraded to hi quality military specs. The transformers are original and are considered probably the strongest point of this amp. Anyway, with the new upgrades, this amp outperforms an original Dynaco ST-70 (which in stock form used cheaper parts).
Tubes complement are brand new JJ EL34, new 5ar4 rectifier, old stock original RCA 7199, the best sounding 7199 around.
The case has been cleaned, but there is rust, marks and general sign of age here and there. This unit has 60 years after all.
This unit has also a modification to balance bias of each tube separately. Very convenient if you want to use non matched old stock tubes.
It comes with its original cage, which though has been painted all black. I'll leave it to the future owner to decide if to give a fresh coat of paint to the cage, or just not use it at all as I do. I like to see the tubes glowing after all!
It is sold as is, due to age, even if with all the new component upgraded it should be good to go for many years to come.
