Apparently the 4066 maximum temperature is 125 degrees C, at least for one manufacturer, but that kind of temperature doesn't sound at all right to me, not for a signal switching chip.

Thanks, that MS16 schematic is the most useful one as it includes the DBX schematics. From that, I can see that the switching is done inside the DBX unit, and that the two SIP ICs as seen on the ebay board are in fact the VCAs used for the DBX process. I had hoped those were resistor packs or...

I can't find the schematics for the DS-8DX, but it seems to use cards for pairs of channels. So you can try swapping the card to a neighbour and see if the problem moves too. There is one such card on ebay but it does only seem to have a 5218p op-amp and a couple of single inline components...

If it helps, I have been using a similar workflow to this since 2004. Sequence most of the song on computer first, and then lay it down to tape track by track, using the synchronizer (a Phil Rees TS-1) to tell the sequencer whereabouts in the song the tape is. This works very well and was the...

If it's possible to get shots from different angles that would help determine whether the suspect parts are reflections or damage.

It's always difficult to tell from a photo. But from that I can make out, they seem okay - assuming the gouge in the middle head is a reflection of the tape guide post, and not actual damage. They are a bit flat and would benefit from relapping but they should have some life left in them as...

I had a lot of fun with this. Vocals and bass were tracked on the TSR-8, and for the transferred to the MX-80 for the final mixdown. The 'crowd' effect at the end had some of the voices recorded with varispeed to give more variety. I ended up using 5 tracks on the TSR-8 just for the voices...

This has been an interesting thread - I always assumed the "OB" designation meant "Outside Broadcast", i.e. it was intended for use in a mobile recording van or something.

Ah, I already sold him mine last year.

Ooh, does that mean more Magic Hero stuff is in the works?

Yes, I can't honestly say I remember hearing about demagnetising video decks. With DCC the heads supposedly have two designs, the digital ones being coils that can't be magnetised, as you point out. The analogue heads are conventional, but can't really be demagnetised as doing so is liable to...

ADAT machines are basically off-the-shelf S-VHS decks, so a demagnetiser that works on a VHS machine should presumably work on an ADAT machine. AFAIK all they did was add new encoding/decoding circuitry on top of the video processing system. Though I must admit, I have no clue how you'd allow...

Thanks! Full disclosure, most of the instruments were sequenced on computer, with the timecode track on tape to keep them locked together during tracking. The bass was tracked on the TSR-8 because it has auto punch-in which is useful for fixing my mistakes, and the key-mashing on the Hammond...

People who were there may snigger, but I have long this weird fixation with 1973 like it was some kind of utopian golden age that I unfortunately missed. So I wrote a song about that. https://dougtheeagle.com/stuff/1973_take1-1644.mp3 Tracking was done on an Otari MX80 24-track, with the...

That's a shame, but nice you managed to return it to him!

That was great. Who's the artist?

Okay, I don't know why the pinch roller isn't moving, and that's absolutely a problem, but the tape is definitely threaded wrong because it needs to go between the capstan shaft and the roller. Otherwise the tape speed will change as the reel goes from start to end.

Incredibly, I still do. The unit and the manual, but no power supply for it. Shipping to the US is likely to be expensive but doable.

To me it looks more like edge damage on the guides, the fact that it's come off as whiskers, for example, looks like it's been shaved off the side of the tape or something. I've not had sticky shed problems much because I started recording after most of the problems were solved with the tape...

I don't know but I'd be very surprised if that was a problem. Such devices generally work by monitoring a tach signal from the deck, which they get even during fast-wind. So I would be astonished if it couldn't cope with the deck's speed changing.
