RE: REVIEW: EAR/Yoshino 868PL Preamplifier (Tube)

I just did a quick check on EBay to see what if any A frame Heerlen Valvos were for sale. I saw only West German-made and Blackburn-made in England by Mullard. My experience is ONLY with the Heerlen-manufactured A frames showing the delta symbols, and NOT with any other Valvos produced elsewhere.
