Author Topic: Unusual Simplex Sound-Head Steven J Hart Master Film Handler Posts: 282 From: WALES, ND, USA Registered: Mar 2004 posted 06-23-2004 09:28 PM                        I recently went to help out a fellow theater owning friend change out his ancient projection and sound heads with a pair he salvaged out of his (now closed) drive-in. He told me they were Simplex 35 projectors on 5-star sound heads. I went ahead and ordered the Kelmar IR reverse scan reader kits and thought we'd be home free. When I arrived to do the job, I found that the soundheads were a model I had never seen before (SH7200) and that the Kelmar reader conversion kits would not fit. My friend told me that his father purchased these units in 1972. Any help you can give identifying these machines is appreciated. We removed the existing Super Simplex projector heads and temporarily mounted the Simplex 35 projector heads on the theater's existing RCA 1040 (yuck) sound heads using kits from Strong (really really expensive), but would like to use the sound heads in question. Front View Closed: Looks pretty standard from the outside. Front View Open: Note the weird pressure pad roller mounted on the same bracket with slit lens.(slit lens removed) The Solar Cell has also been removed. Model Tag: S/N 2294 One equipment dealer told me that my best bet would be to melt them down for scrap metal. I'd sure like a second opinion! Thanks a lot!  |  IP: Logged Mark Gulbrandsen Resident Trollmaster Posts: 16657 From: Music City Registered: Jun 99 posted 06-23-2004 10:38 PM                     Yea, I'm very familiar with them. These are the infamous Simplex "No Star" sound reproducers. The best thing to do is to use the 1040's if they have the flywheel type motors, or better yet get a pair of used 4 Star sound heads... thats about out the best it gets and they hold up very good for D.I. usage. Throw those 7200's in the trash! Mark @ CLACO  |  IP: Logged Paul G.

Wherever it was, I was not very impressed with them.  |  IP: Logged Gordon McLeod Film God Posts: 9532 From: Toronto Ontario Canada Registered: Jun 99 posted 06-23-2004 11:59 PM                     There used to be a retrofit kit for them to make them into a 5 star  |  IP: Logged William Hooper Phenomenal Film Handler Posts: 1879 From: Mobile, AL USA Registered: Jun 99 posted 06-24-2004 01:49 AM                        Wow, thanks for bringing this up & discussing it. I've just been asked to try to bring back from the dead & utilize two of those sound heads in another project. They're the same, right down to the broken knob on the door. The Kelmar red readers don't fit? Does any mfr. have a red reader that fits those 7200's?  |  IP: Logged Steven J Hart Master Film Handler Posts: 282 From: WALES, ND, USA Registered: Mar 2004 posted 06-24-2004 08:40 AM                        Thanks for the information. It doesn't sound good for these "no stars" Were these sound heads made for a very short time? Were they designed and produced while National Screen Service owned Simplex?  |  IP: Logged Ken Layton Phenomenal Film Handler Posts: 1452 From: Olympia, Wash.
