huendeskes 100Watt/ 100 Volt tube power amplifier. 0.775 millivolt input sensitivity. In like-new condition - it was a spare - with an excellent warm, full sound and very good parameters. Multiple 100/4_8_16 ohm output matching transformers are available here for it. Hundreds of watts of transistor amplifiers don't even come close in terms of bandwidth, dynamics, quality, and volume.
