2 kilo schoon aan de haak. Ik zou inderdaad ook een in alle opzichten wat minder zware namen.
Ik zie op de foto's maar drie regulators (7815, 7915 en 7805?). Dan is sowieso heel veel meer dan iets van 1,5A per rail al overkill.

Hmm nu weet ik nog niet wat ik het beste kan nemen.

AC mains adapter
The safest method of supplying power to the 9090 would be to purchase a self-contained AC adapter, of the type built into an external plastic enclosure, often forming the plug itself. This way there is no risk (nor necessity) to come into contact with hazardous mains voltages. The standard 9090 will draw approximately 440mA from a single, 2-wire 15V AC input, so ensure that the adapter is definitely capable of constantly supplying at least 500mA at 15 Volts AC. You cannot use an adapter that has a DC output. It must have AC out. I would prefer to overrate the adapter, so if you can get something nearer to 1 amp, then it would be better.

Internal mains transformer
If you chose to use a mains transformer, then it should have a centre-tapped, or twin secondary. With the centre tap, or common, of the secondary connected to J8 pin 2, the secondary winding end wires are connected to J8 pins 1 and 4. In this configuration each side will draw approximately 200mA. For various reasons I suggest overrating by a factor of about 2, so a transformer of rating 15V – 0 – 15V @ 500mA, or 15 – 0, 15 – 0 @ 15VA total should be used at minimum.

Hoi,
Ik heb nu ook de panelen voor de achterzijde en de 19" cases om het compleet te maken.
hier kan je meer info vinden: rackpanels for a rackmounted 9090 drummachine

hey guys,
Hey, ik heb nog een paar sets liggen, als je de componenten koopt, dan krijg je er een rack backpanel bij. Gewoon "synthforum" in de comment sectie invullen op http://www.synthage.com/groupbuy/groupbuy.php
Cheers,
Jef
