Hm. I'll recheck, but pretty sure every electrolytic in this thing has been replaced by now!

I've got a jh16/100...the deck won't go into play or record mode and stop switch stays lit.
The tape sensor engages but the capstan and pinch roller do not activate.
All other functions work in fast forward and rewind...stop button turns on and off in these modes as well.

I've reflowed the molex and reseated ICs...I get proper voltage on motherboard.
I've checked transistors in the MDA.

I've tried to wiggle the boards and such with no change in behavior.

If I remove the PLAY ic 7410n on the logic board the capstan and pinch roller both activate.

Thanks for all the help:)

Hi Tones:

Looking for a spare scrape flutter filter and reel table. Other than that, for spares, good capstan motors, reel motors and maybe some headstacks to play with.

Nothing that I "need", just a hobbyist having fun.

I thought the forum was remaining open after the earlier risk of closure?

In any event, I have found that bad electrolytics -- invisible, untestable problems, can cause such transport woes.  No big deal to replace them all.

I understand, sadly, that this forum will be disappearing shortly. Couldn't be sorrier to read that, and I'm grateful for all the support I've received here. Perhaps I can sneak one last question in under the wire?

My JH-110b has been mostly trouble-free, but now I'm noticing that near the end of a full-reel rewind, the speed slows. If I stop and then attempt to restart the rewind near the (heavy) end of the reel, the supply side has a good deal of trouble getting up to speed.

I have the manual, and also followed Brian's advice:

"1. Adjust the offset nulls.

2. Adjust the Idle pots.

3. I forget the name of the third set of tweaker pots but they set the play tension. Find the ones NOT labelled Idle or Offset. FF a 10" roll of tape to approx. midpoint (equal amounts of tape on both reels). Go into Play, and adjust the left hand pot so that the "dancer arm" (located near the left hand roller) is approx. midway in position. Then while in Play mode, manually push the pinch roller away from the capstan and adjust the right hand pot so that the tape still runs at approx. the correct speed."

But the issue persists. Scanning other threads, I see this in reference to a 1" 8-track model:

"1. Screw the one revolution every three seconds. Pull the brake solenoid driver to ensure no reel motion. Adjust TP1 and 2 (idle) for 1V each side. This is Steve's method and it works great."

Would this address my issue? I haven't yet done the #1 MCI "fix" (pull and reseat all boards), I suppose I should start there. That said, all red sockets are long gone, all pins on the motherboard have been resoldered.

If you ever decide you wish to toss your MCI JH 110 B or C parts or non-working machines, Please give a holler.

I am in the New England area.

Looking through the MCI newsletters here on this site:


I see there are only a few currently available. It would be fun if anyone has more of them they can scan or send to me for scanning. These should be added to this website if possible.
