Product Description

KR Audio High Vacuum PX25 tubes at True Audiophile

Low Frequency, high power triode. 5-10 Watts of pure class-A power

KR is the world leader in the production of low-frequency power triodes and hi-end audio equipment. 

All products are hand-crafted, starting from the selection of the glass. The high vacuum machines and the choice of the artisan work in both metal, glass blowing and design, chemical and electrical designs plus the absolute refusal to use an automatic line to make tubes is the reason for KR unique high quality.

We have listened to many tubes and KR is the one brand we believe is a true upgrade over the exceptional tubes that ship with Audion tube audio components.

Price is per tube. ie x2 for one pair.
