Excellent quality, and a very close reproduction of the Mullard/Philips type construction. These new production chinese 5AR4 seem to have less problems than the Russian or Czech made GZ34 tubes, and are now available at an excellent price!!! Just $14.99, Compare elsewhere at $18.00!!!
1 piece left in stock supplied in white box. General Electric made GZ34 are rock solid USA made construction and sound excellent. These GE versions of the 5AR4=GZ34=CV1377 have copper lined anodes and are extremely durable.
