1959, actually. One of the most important components in the building of a good sounding tube amp is the output transformer(if you're going to use one). The originals in the ST-70 were pretty darn good. With upgraded RCAs/speaker terminals/PC/chassis wire, more capacitance in the power supply, better coupling caps and resistors; the old jewels can really sing, even with the original driver board. That's not to mention the fun the modding provides.
dynaco st 70 what tubes to replace first
Ive just bought a rebuilt st 70 and am very happy with imaging and sound quality Ive checked the tubes that are with it and they are run of the mill. WANT TO UPGRADE !!
Suggestions please on what order to replace first and if you can; recomendations, Im looking for a creamy thick sound.
Im an old guy and this is my first tube amp and limited knowledge but a fast learner and very excited to go back to non-ordinary reality via sound.
