If you have the R/P head selected, pull the tracking knob out of its 'normal' setting and give it a turn - you should see the RF envelope change level, and if the MD-14 meter switch is set to the upper position, the meter should change along with the envelope.
Set the scope to field rate (2V) - you should see a more or less flat line above the baseline for the feed from whichever video head you've selected, plus a separate RF spike where the sync head picks up around the vertical interval. You'll also need to hook up external reference to the scope. You can get a better feel for what's going on by hooking up a waveform monitor to the 2000's WFM output and selecting the RF envelope on the 2000's front panel. If you get RF on the R/P head but not on the play head, that's usually an indication that either the play head's tip has been damaged, or the sliprings that supply power to the preamp assembly mounted in the upper drum have failed. Second, try switching between the play head and the R/P head on the front panel. You will want to make sure the switch is in the correct position, and verify that the meter itself is working. Is there any engineers around that use to work on the old 1' format? Okay, all of the following assume that you have a tape with known good recording, and that the machine is in PLAY mode.įirst thing to remember is that there's a three-way switch on the front of the MD-14 card that selects the meter function: the upper position is RF from the video head, the lower position is RF from the sync head, and the center position is a rough indication of video level. Could the output be switched to something else? I am going to try to reset all the boards, but I have to get at them first. Is that meeter reading off of the playback head or off of some point later down the line. I am seeing audio and TC on ch 3 so I know I am running over good track.
