Originally: $4.90 Vacuum Tube - 5749 / 6BA6W, Pentode, Remote Cut-Off Miniature remote-cutoff pentode intended for use as a high-gain radio frequency or intermediate-frequency amplifier. Its remote-cutoff characteristic makes it suitable for use in circuits to which it is desired to apply automatic-gain-control.$4.90
Vacuum Tube - 5750 / 6BE6W, Heptode
Miniature pentagrid converter designed for use as a combined mixer and oscillator in superheterodyne circuits.
$4.90 Vacuum Tube - 5751, GE JAN, Dual Triode, HI-MU Miniature high-mu twin triode each section of which as an individual cathode connection suited for use in resistance-coupled voltage amplifiers, phase inverters, multivibrators, and industrial-control circuits where high voltage gain is desired.$69.90
Vacuum Tube - 5751, JJ Electronics
A dual triode that can be used in place of most 12AX7 circuits. The rugged build of this tube and reduced gain (30% less than a 12AX7) can improve headroom and give better control in high gain stages allowing users to more easily dial in sweet spots. The JJ 5751 features a smooth and balanced tone and a detailed response with low noise and low microphonics.
