    These amps are a good buy at full retail, a stone cold bargain at 600!

    to those who may want to dip their toes into a valve amp and do not know much about biasing, Robert would you explain perhaps this sentence a bit more ?


    "Biasing is currently set up for my 8 ohm speaker load you will need a mutimeter to set them differently if needed."

    for 4 ohm speakers once its set up how often would you need to bias the amp and how ?

    I didn't think biasing was a function of the speaker load, I thought it just depended on the electrical characteristics of the individual valves (and the amp itself obviously).

    Thanks for pointing my booboo out. I always used the opportunity to re-bias when swapping speakers - done that too much in my life! Just good practice especially if one tube is pushing and the other pulling. Biasing changes the grid voltages to set the idle current of the output tubes.

    For ease, this amp is 6 ohm tapped so only one set of speaker posts on hand for either 4 or 8 ohm loads (or 6).

    New pictures showing rear of the amp as well as the top where the bias trim pots sit and multimeter is used (behind the KT120 valves). Easy and like most other valve amps.

    Amp will be newly biased before sale and tubes marked up so can just be slotted in - plug and play.

    fantastic Robert , hope this encourages people to buy a lovely amp . I believe the distributors are flamingo audio in hockley Birmingham so some advice available if needed
