The bias circuit was redesigned to be like that of the later Scott amps (with adjustable bias and balance for each channel) which allows for the best fidelity and longest tube life. We carefully chose these parts for the lowest noise, best bass performance and of course long service life. The entire power supply was rebuilt from the ground up using the best parts from Nichicon and Panasonic. Please study the detailed pics carefully!įor the restoration, this unit received an incredibly extensive rebuild. Also please note that we replaced the power transformer with a custom wound Heyboer unit and made a new bottom panel for this amp - this is what this unit needed to be a completed unit on top of the electronics restoration. We could go on and on about the performance but even a quick Google search will show that these are famously great performers once restored properly!Ĭosmetically the unit is in nice shape overall with some face wear - specifically some marks in the bottom left corner and a few scratches in the middle of the faceplate. There is nothing this amp doesn't do very well after the thorough restoration. The stereo imaging on this amp is second to none and there is not a genre of music that this amp can't handle! The phono stage is excellent as well. This design has famously beefy output transformers for the 7189 output tubes with great overall bandwidth, huge bass, perfect balance and amazingly clear, musical highs. This project took us well over two years from start to finish!! It came missing the bottom panel, all of the tubes and the power transformer! The unit was recapped/rebuilt when it was first procured but it took over a year of unsuccessful searching before we decided to have a custom power transformer wound by Heyboer so we could get this unit finished and into the hands of a fellow tube audio enthusiast! For sale is a fully restored HH Scott 299 tube integrated amplifier.
