Roland Jupiter 8 PSU:
The JP-8 Synthesizer is one of the most classic polyphonic synthesizer ever made and is worth more than 10.000 bucks today. ROLAND developed it in the early 80ies and the engineering budget was not limited. The statement from the COE was clear: „do the best polyphonic synthesizer ever made”.

Impressed by that, we made the best PSU’s for the JP-8 some years ago for our own machines and fitted them in more than 40 customers JP-8. Synthtaste has over 25 years experience in development and refurbishing vintage Synthesizers. Our clients are from all over the world: Germany, EU, USA.

Now we’re going online with a new design for a drop in PSU. Simple to install, no drilling, no double connectors, no high voltage on PCB, following international safety, engineering rules, and CE conform!

- Solid and reliable design (>40 machines without any issue for the past 8 years)
-   all original PSU parts are substituted, even the heavy transformer
- Universal AC input / full range 88–264 V AC, 50/60 Hz - for worldwide use without any power selector
- Main transformers are CE certified
- Fully encapsulated, no EMV issues
- Solid crimp connectors, NO input voltages on the PSU PCB (!)
- Protections: short circuit / overload / over voltage
- No noise
- Very low heat
- Fully analogue regulated
- All voltages can be adjusted to 0,000 V accuracy
- +/- 15 V tracked to get a 100 % symmetrical output
- Additional fuses and safety diodes
- Easy to install
- Extra power for a KENTON MIDI kit (some guys forget about it…)
– engineered and built in Germany

Specifications and details may be subject to change without prior notice.

IMPORTANT: Non technicians should not open up their own synthesizers (or any electronic machine for that matter) as lethal electrical wires are exposed. The power chord should always be UNPLUGGED from the wall (it's not good enough to just turn the power switch off) before opening up any electrical machine.
