Do it yourself Reel to reel for sale.

Next Sony in my popular TC-model has many similarity as TC-366, 4-track stereo, 3 speeds and slanted cabinet. Same frequency response, flutter and wow. Also signal to noise ratio (52dB) as TC-366.

  • A few changes were made, 4 more transistors, different heads F&F (ferrite & ferrite)=
  • Extended frequency response with high-bias tape. Higher reliability..1/200 the wear of earlier models. Mirror smooth surface contact with the tape.
  • The symbol F&F means the core material plus guard portion, of the heads are all ferrite. This prevents uneven head wear and maintains, a precisely parallel head gap for a more extended period.
  • Slight wider + taller cabinet.
  • Built in reel lock-downs instead for rubber-holders.
  • Mic attenuation was added instead for noise-suppress option.
  • Line output adjustment control on 2 of the 6 different models made between 1972 and 1975.

  • 7-1/2 and 3-3/4 are ideal for recording music when best sound is desired.
  • 1-7/8 is ideal for speech.
  • Sound on Sound and Echo recording can be done.
