Rare Perfect Quad.
Old UK production and Brand New .

A matched quad of old Philips Mullard Blackburn-factory kM2-series 6BQ5/EL84.

These four test within a few milliamps of each other.

These came in a Philips commercial bulk pack. I've included four nice new boxes that originally housed weird 10-pin TV valves. ...So you can write whatever you like, on them.

The 'design-center' value for the EL84 is 48milliamps , at 250V anode,screen, and -7.3V grid1

**Tested on a DC regulated modded AVO 163 tester.

These four test 47,47,49,50 milliamps.

A lucky-dip random quad of EL84 can easily vary from 38----60 milliamps.
So these are a valuable set of matching valves.

You can make out slight brown stains near the anode holes. This seems to happen in the factory as the valve is fired up, and is a well known quirk of the Mullard EL84. Probably over half of them exhibit these birthmarks.

No gas or leakages

No overseas shipping
