Skyline Forty Nine P Synth/Organ Teardown

Forty Nine P.  Rare piece of gear.

I recently picked up a Skyline Forty-Nine P.  More of an electric organ than a synth, but worth a look nonetheless. 

Presently it isn't working, but it should be back to full health soon.  Once working, I'll upload a selection of pieces/performances to YouTube.

Numerous photos below of the innards (plus the service manual). 

A stand was also included, but I haven't taken photos of it.  

The instrument is quite big - I haven't measured it yet, but it looks almost exactly the same size as the Matrixbrute.  Being 49-key, the size is going to be similar - but the main panel (metal) is bigger than I imagined it would be. 


External

Rear panel.  Note the broken/missing power switch.

Stand attachment point; 5 possible angles

Speaker on underside.  The sound of these is usually pretty strong.

Chord tonality selector.  Note the faux leather finish.

Voice switches

Mixer

Percussion section



Under the Hood/Service Manual

The service manual was stapled inside, to the R of the speaker.  




Almost 40 years old!  Vintage gear.








Internal

A few of the boards/components etc.

The tech spec/PDF's for most of the chips can be found online.  

Power supply unit




Percussion section

Voice board

Front of voice board

Main board, underneath the keys

Chips are also used on... Farfisa.  Good chips!  Circuit benders - note the Texas Instruments logo off to the R.  

More TI.  Once the machine is up & running, I'll maybe look into some circuit bending on the Skyline.
The main chips are possibly worth more than the value of the instrument
















All best
Kris
