Here we have a selection of what are believed NOS 6D6 valves.  These came to us with the remnants of cardboard packaging, tainted with aurobacidium pullulans - black mould.  We threw away the packaging, sanitized then tested the valves and here they are offered for sale to help your HRO - or indeed any other use you may have for them.    Below is provided a listing of the valve line ups for the famed HRO range to hekp you decide which or how many of these you may wish to purchase.
