Final sell off of these ultra low noise non-microphonic vintage 12AX7 tubes
These are super sweet sounding tubes and they will be gone fast
Made in 1963 -65 at the Philips Amperex factories
Screened specifically for use in high fidelity console units and organs.
They're very sought after in the audio file sector.
Also the Canadian made Philips "r" coded version of these and these 1965 date coded were tooled to the exact same standards!
These are excellent tubes and sound better than many Telefunkens
You'd probably find these Philips Amperex more warmer, articulate, nice bass and little more top end air high than most Mullards which tend to be a tad laid back.
These Philips Amperex Electrohome are similar to Mullards having that Mullard flash on start up.
Try them in your phono stage, amps pre amps!
Most of these tubes were only slightly used from 20-80 hours playing time
Just enough for great burn ins!

These are probably the rarest of the Philips Amperex 12AX7 vacuum tubes:
These select organ grade 12AX7.
This tube was made Philips/Amperex factories that made the Bugle Boy tubes. However, these special tooled tubes received extensive aftermarket screening for low noise and tested for non-microphonics, plus uniform balanced output from each triode.
They were even used in EKG and ECG machines, and tube noise could not be allowed as it would invalidate the test results. In music amplification, these tubes sound superb.
The music emerges out of a black background of silence, and the sonics are three dimensional. It will outperform about every other 12AX7 ever made!
Beautiful break up when used in the V1 position in guitar amps, with a sweet tone that has to be heard to be believed.

These tubes test very strong as NOS unused at:
Tube 1: 1200-1250
Tube 2: 1200/1200
Tube 3: 1200/1140
Tube 4: 1120/1150
Tested on our B K 747 tube tester where 50 is minimum good.

They needed to be the best, so they used Philips Amperex made in Holland 12AX7's that were made for the most critical applications.
Silk screening is intact on all tubes!
