Take traditional worries out of old-fashioned setters.

Thousands of organs still have setter boards. Some players still prefer them. But they don't last. Relay armatures loosen. Contacts oxidise and burn. Not to mention the strain on a Console-wirer's vision. 

Next time you rebuild a setter-board, fit SSOS piston relays. They're compact, contact-free and even draw less operating power than an old-style relay coil. Each relay's 7-amp load is just fed through diodes to the common contact on the setter switches. And the easily-spotted, well-spaced pins save many a headache and weary eye.

• 7-amp load
• "Pistons Coupled" possible via an SSOS coupling relay
• One relay occupies only 102mm x 33mm (4" x 1 ¼")
• Positive feed from piston, negative output

More than one relay for one piston.

If you've more than 7 amps' worth of magnets to power, SSOS Piston Relays can simply be joined up and wired to the same piston. Your only constraint is the size of the organ! 

Tremulant Pulsator

Adjust your tremulants according to taste.

Tremulants are personal things. Certain speeds and depths suit particular pieces, but no two organists never agree on what they actually are. No wonder traditional motor-tremulants organist - is only happy with a particular speed and depth. well as reversing stops, electro-mechanical reversers often trigger choruses of thumps and bangs. Not to mention the contact-adjuster's cursing. Often it's either no-go or perpetual vibratory motion.

SSOS's Reverser Units take the black art out of reversible pistons. They're silent, reliable and easy to install, with no fiddly contacts to oxidise, adjust or swear at. As well as solid state stop actions, they'll fit any conventional electric or electro-pneumatic action with minimal change.

• Easy pin connections
• One reverser occupies only 64mm x 45mm (1 ¾" x 2 ½")
• Positive feed from pistons and stops, negative output
• Controls coils up to 0.6 amperes

Any stops, no exceptions.

There are almost as many stop controls as console styles. Fear not. SSOS reverser units will happily control any electric or electro-pneumatic drawknob and tablet. Age and obscurity is no problem.

Bus Bar Switching Relay

Cut the hassle with cut returns.

In straight organs, pipe ranks with individual magnets can be switched by simply cutting their return. There's one snag. Cut-returns often mean heavy-duty contacts. Think wear, sparks and burning.

With SSOS Busbar Switching Relays, it's silent, clean and easy. A rank's magnets are supplied with negative outputs from key relays, and the busbar relay interrupts the positive return. Use them, too, for cutting out primary actions and isolating systems, ranks and off-notes when stops aren't in use.

• Simple to mount and install
• Outside dimensions 128 mm x 36mm (5 1/8" x 1 3/8")
• 5-amp load
• Positive or negative control, both with positive output
• Fully spark-suppressed at input and output

Double the relay and double the load.

SSOS's Busbar Switching Relays handle a 5-amp load. To double it, just split the return rail and apply a relay to each section. Remember - if you're feeding more than one magnet from a single source, make sure each has a diode to avoid runbacks and untraceable phantoms!
