Part  I Part  II Part  III Part  IV

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.

TU-8500  NOS 5965A  Phono Preamp Kit

For the past 8 years, hobbyists have been asking for certain features to modify the TU-875 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-875.

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