Re: Solus brand EL34?
If that valve was actually made in Britain then it was probably surplus from Mullard or Brimar. However, it could be that it is actually an RFT made in East Germany and the marking just tells lies. Is there a dimple in the top of the glass?
RFT valves are quite good, and their EL34 is still sought after by people who cannot afford Mullard.
