Product information "KT88-STR TAD Premium Matched"
Our favourite Tube in the KT88 / 6550 Class
 
The latest version of our TAD KT88-STR is built in the style of the early British MOV KT88. It has the same big and heavy glass envelope and beautifully polished metal base. Its wonderful tone and great appearance make this tube the most attractive choice for high-end audio applications and powerful bass guitar amps.
It offers a vivid and three-dimensional tone, pleasingly warm, detailed and with subtle highs. A very musical reaction, with great sound and finest details in mids and top-end; a linear and harmonious overall response with a very natural tone, make the TAD KT88-STR our favorite tube in the KT88 and 6550A class.

Customer evaluation for "KT88-STR TAD Premium Matched"
From: On: 26 Nov 2021

Great sound

I replaced my gec in my tva-1 this was the 3rd tube I tried. The sound was very comparable to the gec. Far superior to the other tubes.

From: On: 5 Jul 2018

Following the purchase of these Tubes TAD KT88 STR, and after thirty hours I am filled by listening to these tubes.

My PP-UL Amplifier is homemade, and after listening to EH KT88 EH KT90 and JJ KT88.

I have to admit that these TAD Tubes are really hard-hitting in a HIFI listening.

Thanks to TubeAmpDoctor for making me discover these KT88, and thanks to Stefan for these technical advices.
