The KT88 was introduced originally by General Electric Company (GEC) in 1956 as a larger variant of the KT66 beam power "kinkless tetrode". It was manufactured in the UK by the MOV (Marconi-Osram Valve) subsidiary of GEC, and also labelled as IEC/Mullard. The 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. It features a gold control grid for 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 three-dimensional tone with pleasingly full warmth and fine, subtle highs. A very musical response, with great sound and finest details in the mids and top-end; a linear and harmonious overall response with a very organic tone, make the TAD KT88-STR REDBASE our favorite tube in the KT88 and 6550A class," states the German company.
Among the outstanding features of the new TAD KT88-STR REDBASE, the company specifically underlines its sweet, full-bodied tone with silky highs, superb responsiveness, and outstanding dynamics. All these tubes are individually tested, selected, and approved, with premium matched sets available ex-stock.
The TAD REDBASE series is built on an optimized production. It is therefore a completely new development, combining the latest manufacturing techniques with traditional design and quality. In preparation for the TAD-premium matching process, all TAD REDBASE series tubes receive a special, additional burn-in and formatting process in Germany, optimizing the quality of the cathode emission and achieving a detailed sound structure.
Primarily serving the guitar amplification and effects market, which still involves the highest volumes in audio applications for tubes, Tube Amp Doctor has been around since 1993. With a continuously growing reputation and an expanding product line of top-quality tube amp equipment and parts, TAD has become Europe’s leading tube supplier, sourcing its tubes from one of the only remaining manufacturers in China.
