AMPEREX  6R4 - EC81  RADIO TUBE  HOLLAND

NOS NIB  TESTS  GOOD @ 89

WHERE MINIMUM GOOD IS 65   

Great vintage tube guaranteed to perform.  Tube has been tested on a recently cleaned and calibrated B & K 707 tube tester and tests at 89 which is good. 

I have hundreds of tubes I will be listing.  All tubes I sell are tested before listing and are guaranteed.  Please view the provided pictures above to gauge the condition of the boxes which will vary.  Note, some boxes may have ripped or torn flaps as they are quite fragile due to age and wear.  All tubes will be packaged with care and shipped in a sturdy box for safe delivery. The tube/box you see is the tube/box you receive.

Please note that most of the items I sell come from auctions and estate sales and boxes may possibly have storage odors (mildew, smoke, staleness etc.) over which I have no control.
