    Description

    THE PICS DO NOT DO THIS AMP JUSTICE!!!
    I built this amp originally for 45 tubes, which I wasnt happy with due to NOS prices
    I decided to build something really different, but also excellent sound and tube replacements that can be had for a fraction of NOS 45s, 2a3s, and 300bs
    I designed this amp and did all the metal work and I also powder coated the chassis as well as the transformer endbells
    The output and interstage transformers were made by Electraprint, the power transformer is Edcor and the bigger choke is Hammond
    The driver tubes are triode strapped Amperex gold pin PQ 7788 (E810F) with LED bias
    Power tubes are triode strapped HY69 (HY69 is a directly heated relative of the 807 and 6L6GC)
    The HY69 are have a fantastic glow thanks to their Thoriated Tungsten filaments!
    The output is around 2-4 watts
    The tube rectifier is a Xenon gas 3B24
    The sound of this amp is simply amazing! You just gotta hear it!
    Power supply is a well filtered LCLCRC
    The filament supply for the HY69 is in a separate chassis box which is also included
    I spent a lot of time building this amp and I am very proud of it. I am only selling it because have no more room for future amp builds
