I will find out visually thanks Phil, come the time as I will remove the outer case to gain access to the head terminals to remove the head.

I was just curious to find out in advance the configuration but no one seems to know for certain.

It's just a shame I cannot find out what all the tags mean on the end of the head codes.

All we seem to know so far is that RF is a recording / playback head while R coded heads are just designed to be used as playback heads as in their monitoring duties for the machines these are fitted to.

Still leaves RS and SA 464 heads unanswered for though sadly. [Confused]

Hi Andrew,
For my information, where did you report "SA" & "RS" ?

If this is on Beaulieu's, What are the models (means, HTI, Studio, etc....)

If they come from any of these models which were producted untill 90's, that could be some uprated Heads showing improved performances.
Also, tell me if these heads (RS, SA) are showing a plastic body (inside the metal cup).

Yes they can have removable plastic inserts for use with other machines other than Beaulieu, Phil,.. and no I have not seen these types fitted to either of my Beaulieu machines, just my 3 Bauer T610's (but not always these two types of head).

I wouldn't know what type is fitted to the later HTI or Studio models Phil as I simply don't own one.. (yet [Big Grin]

[Big Grin]

[Wink]

)

Perhaps someone like Alan Rik who does own one or two of these models could take a peek at his heads and reference their codes for us all here?

Does they look like this :

This is what I installed 25 years ago on my first Beaulieu.

And works pretty good.
There is "no name" written on the cup. It is supposed to be "BOGEN" style

No Phil, they don't, they just look the same as any other 464 type head and have the Woelke logo printed on them with the ident coding 464 RS or 464 SA after the Manufacturer Ident.

They are all original heads.

Just an other information Andrew, I had to replace the guide plate below during head replacement due to some extra wears on pins and somewhere else.
Once pins are worn, you can experience loss of sound quality .....

Cheers Phil, that is something i hadn't previously considered given that this component is metal! [Wink]

[Wink]

I'd only considered the "Pressers" being worn, as a reason to change out any other component associated with poor sound reproduction from either track other than of course, the actual heads themselves.

Top tip Phil thanks and once again, the power of the "collective" surfaces within hours of stating as much. [Wink]

[Wink]

[Smile]

Thin washers or shims fitted beneath this plate would sufficiently counteract against any wear to the pins and still should leave the film path "safe".

Yes Andrew, this is metal but mainly brass (plate and pins)material, to stay amagnetic of course.
Unfortunately Chromium "flash" coating is a very ordinary quality. This is not Hard Chrome Plating quality.

I have to say Phil, neither of my own look like the colour of that one there. I will grab a few photos of them later fitted in place.

The "yellow" colour is due to missing light (no flash light).

This is actually "white" chrome

Hanging out in customs looks like. Because of the weight they must think it's an IED!

Thanks Alan and can't wait to hear you have it back, safe and sound and practically perfect in every way. [Wink]

[Wink]

Once you've had chance to make up for lost time I'd really appreciate it if you could reference your head codes for us all please.
It would be interesting to see if they differ in any way on the later models.

(No pulling apart necessary for any of this btw)

As regards differences between record and playback heads, I once read in a very much aknowledgeable audio magazine, record playback heads have narrower gaps than playback only heads.

In the case of S/8, though, it should be noted the PB head and the Rec head are actually the same to retain the standard 18 frame image-to-sound separation, the monitoring head only being used during recording for checking final quality in real time...

Thanks Phil & Maurizio, much appreciated. [Wink]

[Wink]

The playback only head was the monitoring head in this case Maurizio as it is never used to record anything, only to monitor sound after recording has already taken place so it's positional placement as I understand it is unimportant except to say these heads cannot be utilized as a record / playback head by swapping the two over.
