Brand Spanking New, MINT NOS HITACHI JAPAN 5AR4 GZ34 Tubes with Chrome Sides on Plates. Relabed by British re-brander Zaerix. Hitachi used to collaborate with GE, and these seem to be a variation of the GE design. Tube glass and plate size is bigger and construction looks more robust than the GEs. Repackaged in generic white boxes from bulk.

This tube is far superior to the current production GZ34 firecrackers and good value as compared to overpriced Mullards.

Tested and matched on Calibrated Hickok 752.

Price = $60 per tube.
