All Psvane tubes get retested to ensure the perfect quality even after the long trip from factory to us.

the NEW Psvane MKII T-Series:

Carbon coating inside the glass envelope for better heat dissipation and stability of electron tube performance.

Teflon Base with Oxidized Aluminum Collar:
The MKII series tubes use exquisite Teflon material for the base to improve on low conductivity and stability. The amber color oxidized aluminum collar around the Teflon base is will avoid corrosion as well as finger prints to maintain a prestige appearance.

Psvane logo and serial number
The Psvane logo and serial number are engraved on the base: The Psvane MKII series have its logo and serial number engraved in the tube base facing all in same direction. No print on the glass does disturb the appearance of the beautiful shaped glass envelope.

Glass Quality:
A higher quality glass is used for the MKII series to increase the reliability and stability which does slightly increase the total weight of each tube.

Sound Quality:
The MKII series offers superb sound quality. The new coating materials offer an even better music presentation. Even compared to the great sounding Mark I T-Series you will experience slight 3D imaging improvement, layering and clarity

Tung-Sol KT150 beam power tetrode
 
manufacturer information:
With a massive plate dissipation of 70 watts, the Tung-Sol KT150 is the most powerful octal beam tetrode ever produced. A pair of KT150s can allow an amplifier with a power output approaching 300 watts to be built.
 
The Tung-Sol KT150 glass envelope is a special egg shaped balloon that was developed to improve thermal dissipation and maintain a superior vacuum for the best sound. The fact that the glass envelope has no flat sides means the Tung-Sol KT150 has no problems with microphonics.
 
The KT150 has same pin layout as KT88, KT100 and KT120 tubes as well as 6550A, EL34 and 6L6GC.

TAD – KT88-STR REDBASE – analog sound in perfect audio-quality

High Performance Audio Beam Power Tetrode

Our new TAD KT88-STR REDBASE is built in the style of the early British MOV KT88 with the big and heavy glass envelope and beautifully polished metal base.
The REDBASE features a gold control grid for outstanding low-noise performance and reliable stability.
A breath-takingly big and precise tone and great appearance make the new TAD KT88-STR REDBASE the best choice for both, high-end audio
applications and powerful bass guitar amps, providing a natural and threedimensional tone with pleasingly full warmth and fine, subtle highs.

A very musical response, with great sound and finest details in mids and top-end; a linear and harmonious overall response with a very organic tone, make the TAD KT88-STR REDBASE our favourite tube in the KT88 and 6550A class.

New Sensor now announces the Tung-Sol KT120, which has a plate dissipation of 60 watts, making it the most powerful tube in the 6550/KT88/KT90 family. A pair of these tubes in push-pull configuration can deliver power levels of 150 or more watts. When used at the parameters found in existing 6550/KT88/KT90 circuits, the Tung-Sol KT120 is impervious to overload, delivering peak power with extreme reliability and long tube life. However, taking advantage of the higher current handling capacity of these tubes, a very unique and super powerful and stable amp can be designed using the Tung-Sol KT-120.

We cannot accept orders for octets.  Close quads with same ip# possible.
