Part 5: MCI JH110B Rebuild - Final Stretch...

By Tim Dolbear

The Sony MCI JH-110B Rebuld Saga...

Just finished re-cap'ing the audio penthouse. Audio is much more stable sounding and feeling. Operations are smooth and how they should be.  We just ordered the MRL alignment tape from MARA Machines ( They are the kings of rebuilding MCI machines). Once the tape arrives we will do final alignment and setup and we are done!

We do have 2 remaining little fixes we need to address that will not stop us from using the machine in the meantime:

First there is still the transport issue that when the small board/joystick for the MVC is connected, the Rewind and FF buttons will not trigger the motors. The lifter will go, lights changed, but no movement. I can RR and FF using the Joystick just fine. When I unplug the MVC, RR and FF work perfectly BUT the digital count then does not work anymore and sits at 0.10... I do not need the MVC, but would like the RTZ and counter to operate.  Anyone have an idea?

Second, the channel 1 input into the Audio Penthouse, the connector can loose contact even though its screwed into place, something breaks contact when I open and close the drawer... simple fix, just annoying.

But right now we can print to tape and playback and the machine is not even bias/aligned, so good sign!

That's all for now, till next update!
