hello everyone I have problem with my nakamichi bx-1 tape deck it is 2 head system.
with following problem topics.
1. left channel has a louder than right channel after recording. (it same with new cassettle)
2. how to adjust bias.
i don't have any tools to calibration a tape deck.
can should i do
(i apologise for broken english)

Hey all! I finally decided to put the Rec/Repro cards back in the little Fostex 1/4" 8-track. Before anyone yells at me, it was free, m'kay!

Anyway, I need to calibrate the deck, but I'm not quite sure which trim pot I should start with. I've got my 1kHz tone on tape from another deck that was pretty close to calibrated (I realize this is a poor way to do it, but bear with me).
