We have on offer today, a matched pair of these sonically lush high performance triodes. They carry base markings in red ink and etched cartouche on the envelope. Although both GE Canada manufacture with successive date codes I5 QX & H5QX, the former carries Marconi Radiotron branding whereas the latter carries GE Electronic Tube branding. Whatever, both devices show good inter and intra device matching.
