Further Information: 

Mullard GZ34 Blackburn f31 double O getter.

I do not have a tester to confirm value hence reduced price. I used for under 50 hours. It works and sounds as it should. It looks barely used.

Pick up available at Ultimo NSW2007 office hours or Lindfield NSW2070 after hours. 

Postage $18 flat insured or $10 uninsured with tracking only.

The very best of the GZ34 tube. Selling well below market value.
