Hi again,
Wanted to start a new fresh thread on this. I have a YTT-1144-2 alignment tape. The service manual references YTT-11442 no dash. The guy talking at the beginning of the tape says it's full track. But I can't seem to get it to -10dB on just about every other track. This shows the 1kHz tone being played back with just about every playback trimmer almost at max except track 1 adjusted for ~316mV as measured by voltmeter attached to the output. (via 50 ohm cable). I could get that card to read properly (more or less, it averages out to 316mv).
However, swapping cards for 1 and 2, you get this when playing back the alignment tape:
This is without any further adjustment, simply swapping the already adjusted card in to slot two and the card that just had the pot near max into slot one. So the playback that was set OK on track 1, is now not OK when you slide that card into track 2.
I'm showing the deck's VU meters for reference, but the actual output of channel two is here with the trim pot nearly maxed out, it's about 1/2 of where it should be:
This is the tape:
I had calibrated the meters previously per the manual to register 0VU at -10dB. So I recorded a nominal -10dB 1kHz tone to 1 & 2 on to 456. The record level probably needs adjustment, but playback was otherwise fine on both tracks albeit about 1-2dB higher than it should have been. (Noting that the playback level adjustment is probably not correct)
Thoughts? I vaguely recall a thread here that certain TEAC 8 track tapes weren't full track, which would seem to account for this anomaly.??? I'm thinking of springing for a four tone, four minute MRL tape which are quite a bit cheaper and should be sufficient for this purpose.
EDIT: Here is the thread where "Beck" says the YTT-1144-2 is *not* full track.
Which calibration tape?
