Sunday, July 24th, 2022
No mid-fi, no gimmicks, no junk. Each piece of equipment is cosmetically restored and fully tested in our well-equipped lab by an engineer with 30+ years of experience in the HiFi world. Through our sister company, which is an authorized dealer for McIntosh, Audio Research, Sonus Faber, ClearAudio, Project, and Sony ES, we have access to OEM parts, service, and support. This amplifier is a hot rodded version of the famous Dynaco ST-70 stereo tube amplifier. The modification kit was provided by and is referred to as the ST-120. This kit features larger power and output transformers which enables the amp to handle larger output tubes. This amp is currently fitted with KT-90 type tubes but can also run 6550′s and others. It has two top panel mounted switches that allow it to be toggled between Triode and Ultralinear modes. Triode operation yields about 40W per channel while Ultralinear delivers close to 60W per channel. The kit builder converted the front panel stereo / mono control to a 4 ohm / 8 ohm switch. The unit also features a WZ68 solid state rectifier. Yes – Printed Copy. Yes – Power Only. We have too many items for sale and it’s nearly impossible to keep track of offers outside of the official system. We accept trade-ins of equal or lesser value under certain conditions. Please visit our website to submit your gear for full consideration. We will only consider high-end equipment from mainstream manufacturers such as McIntosh, Mark Levinson, Audio Research, Krell, etc. And will typically pass on displays, projectors, receivers, dated surround processors, and mid-fi equipment of any type. We will offer a fair value for your equipment, but keep in mind we’re running a business and will need to be able to resell the equipment at a profit after investing a great deal of time and resources in testing, certifying, repairing, cleaning, and packaging the incoming equipment.
