Redwingnine Posted November 9, 2020 Report Posted November 9, 2020 Just picked up a DIY Kludge headphone amp. The base circuit came from a Vacuum Tube Valley #11 on page 24 and 25. Here is the link: https://web.archive.org/web/20131122141643if_/http://www.jumpjet.info/Pioneering-Wireless/eMagazines/VTV/VTV11.pdf A few minor mods were made to improve the performance, such as additional power supply filtering, HEXFREDS, DCed all filaments, etc. This amp sounds great. Has NOS Tung-Sol 6080 and 6SL7 tubes. Has plenty of power. Easily drives Abyss 1266 phi. 2 Quote
