A matched pair of MULLARD EL 34XF1 tubes.Manufactured at the Mullard Blackburn plant 1959.Double oo top halo getters.These are the real deal,one of the most accomplished EL34 tube ever marketed.Acquired froma private collector in South Florida.I have been selling off my collection of rare vintage tubes for the last year.The tubes have been powered up for several hours to ensure they are without issue.
No defects,microphonics,shorts or leaks.Tested 11,000 on a B&K tube tester which is essentially NOS.The etching is no longer visible,after 64 years this is not uncommon.I can attest to the provenance of this pair.
