Apart from the penthouses and heads, have one set, know where I can find another, small tooth sprockets (only one needs changing), 2.55 aperture plates and giving everything a good going over with a demagnetiser, what else will be needed? On this site there is a manual for a Dolby MPU-1 pre-amp unit, but this only mentions using it with the CP-100 and 200. Would it be possible to use one of these with the CP-65 which she has? If so, what cards would it need in it (for two projectors, 35mm only), do they ever turn up secondhand, and what would one be likely to cost ?

This is to go into a box which is a real showpiece, makeshift looking solutions would not be popular with the owner!

It is not posible to move the optical axis, we would just have to project a slightly off-centre image, and adjust the screen masking to match, but she does this anyway, for silent films.

Thanks for any advice, I've run mag a few times, but never had to set it up.

Budget is tight, this is the private home cinema of someone I was at school with, many years ago. She bought the CP-65, and the speakers, much of the other equipment was donated, or rescued from places which were throwing it out. Two 1950s Westars with AEI xenons, 500 Watts, I think. Screen is about three metres. I have projected there from time to time for her and her husband. It's several hundred miles from where I live, so I don't get to see them very often. Equipment has been restored to the condition it was in when it left the factory. I wish I had something like this, (and somewhere to put it). I installed some of the equipment, including the original sound system, about five years ago, but not the CP-65, which went in quite recently.

"Quite why they want to install 4 track mag when there are no mag prints available, and most modern type projectors will not have the (Fox Hole Sprockets) if they are, they are mostly in private collections or at the NFA."

She is a keen film fan, and collector, has several friends who are the same, and wants to be able to run original magnetic prints. At the moment she has my 'Perspecta' card on loan for something she ran recently, and has talked about setting up for 3D.

The SMART SMP-435 is out of production.

If you can find an old SMART SMP-430 it has the filter for the control tone. One nice thing is it will handle two projector 4-track and is only 1-U tall. If memory serves, there are two tunable filters to allow you to dial out the 12KHz tone based on how your projectors run.

For Dolby, you would need an MPU-1 35/2. It also needs a 24VDC power supply. It would also need the optional Cat. 93 12KHz switch card. Dolby's MPU is also now discontinued.

Panastereo offers a 1-U MPU (the number escapes me at the moment) in addition to their world famous CSP-4600.

The CSP-4600 will add true mag capability to the CP-65. It has the 35mm 4-track stuff built in. For a 2-projector system, you would need an additional mag preamp card (it comes with one 6-channel card)...it would then feed to the CP-65.

I thought that all sprockets were still made to fit Foxhole. As during the last five years I had replacement intermittent assemblies, and replaced all the sprockets on the Westar (Century) projectors, and RCA 9031 soundheads. All renewals were definitely Foxhole type, I could still run a 2.55:1 grid 4 track magnetic test film.

Are standard hole sprockets fitted to the latest Kineton projectors, or is there still an option ?

Ben,

Interesting that a Panastereo System is installed at the NFT 1. These processors have been highly spoken of in another thread, I seem to remember. Are there any other installations in the UK, and who is the supplier ?? Thanks.

"The original VKF sprocket was designed over 30 years ago with the intent of reducing film damage, projector maintenance and cleaning. It was designed to handle both standard 35mm and cinemascope prints. Since the only 35mm format in use today is per ANSI 139-1996 (ks ), LaVezzi has redesigned the VKF sprocket accordingly. This design, known as ‘VKFII’, has wider teeth which are centered on the perforations."

Couldn't find any 4 track pink noise anywhere, tried all over the place. Finally found some, somebody who used to be a projectionist had some; he works in the same college as me! (Different department.)

Brad, you'll never get my 35mm mag stash! Though I have striped PN, some use full coat pink noise (more available) and take into account the fringing compensation (due to the full coat having a wider track than the striped media). It will show up as an exaggerated bass. Also, track 4, surround will have the perforations mucking with you.
