General Discussion / Re: Full track playback with two track heads
« Last post by cvandyke on April 18, 2018, 09:19:05 AM »
Thanks! I didn't particularly like the bass on the mono tapes I played and I hope this is the cause. The tapes are production masters which contain transfers from 78 sides so it's just as likely be the recording.

Another question about this general subject: is there a reasonable way to determine if a tape labeled "mono" was recorded as full track or two track mono? The tapes I have so far are labeled so it's clear but it seems likely I'll face this issue in the future.

I do have a mono repro head for my deck (Otari MTR10). I need to mount it and to figure out how I want to handle routing the signal from the head. I really don't want to make any non-reversible changes, have an awkward cable dangling, or put a switch in the signal path. I've already spent some time pondering how to proceed and, so far, I've come up empty.

PM me.   Larry

There are two outfits currently making the type of heads we need for audio.

AM Belgium is a pretty large company, with most of their business in data, credit card scanners and other fields. But they do make--and have made for years--audio heads.

Flux Magnetics in California make very high quality audio heads, and audio heads are their only business.

Good luck with your new machine.

This is a forum dedicated to reel to reel tape. It might not be the best place to look for help on two pieces of gear that aren't involved in tape playback.

In case you haven't contacted them already, you might get some help from Mark Levinson's current company: Daniel Hertz S.A. in Switzerland.

One other thing happens, which is generally considered a downside but someone might prefer it in some circumstances.

Whenever you play back a wide track recording on a narrower band playback head it is subject to a phenomenon called "fringing." The effect is to raise the low frequency content several dB above the balance that was recorded.

What happens is that the recorded portion that lies outside the track width of the playback head adds its low frequency content to the part that is picked up normally. It's like pushing the Loudness button, except that you can't turn it off if you don't like the effect.

Hi Kostas,

As you are probably aware, The Stella's used what Nortronics called "B case" heads, a "standardized" shape that a few manufacturers made.  They used Bogen (German) originally for PB and Record with Wolke erase, then switched to Nortronics PB/R.

I believe the only entity still making heads is AMR? or something like that in Europe - they made the later butterfly heads for the Stella SM.  O yeah, I believe that Flux Magnetics also makes B case units - at least playback.

Depending on how many you need, I have some record and erase Pro Nortronics.  Want to keep the few PB heads I have as there are no more.  Also suggest contacting John French to see what he may have.  I also have a few Pro nortronics heads that are fine but could use a relap.

Would there be any negative sonic effects of playing back a 1/4" full track tape with a two track head? Obviously, you don't get the benefits of the whole recorded width of tape. Are there any other downsides?

Maybe a simple question with a more complicated answer...
"Which trimmers to use on the Nagra T to adjust the levels ?"

Thanks for the all the good music on tape !
