Elekit TU-8500

TU-8500 5965A/12AU7 Phono Amplifier Kit  

For  the past 8  years, hobbyists have been asking for certain features to modify the  TU-875 phono amp kit.  The highly regarded Elekit designer, Mr. Fujita, has taken all those  specific features  and specifications  into consideration and  we are happy  to welcome the release of the newly designed TU-8500 .

The new TU-8500 has a lot more improvements from its predecessor and has to stand its ground in a considerably more competitive marketplace.

Elekit TU-8500 I rolled in RCA 6201 black plates and the sound was so good I let them stay. So users should try 12AT7 family tubes too! Set to unity gain (actually 1.1), the Elekit performed flawlessly as a buffer amp. Its neutrality allowed the full flavor of the Langevin to emerge. Commendable! Too bad I do not have the iFi iTube on hand to compare (next year perhaps). Not surprisingly, it also functions very well as a phono amp for the Raos MC Mono cartridge (shall be covered in a coming article). With this, I think I shall conclude my series on this gem.
