Recommended PSU

[Vayner]

Hi,

I'm starting my DIY modular experience with some CGS kits. I was told a PSU ordered from Curetronic would do the trick, but I've sent an order in several times without reply now.

Which PSU would you recommend for somebody starting with a relatively small setup? (currently a CGS VCO, Tube VCA, VCF and Dual LFO)

I'm looking for a built solution. Soldering these modules is one thing, not getting electrocuted while not understanding how to make a PSU is another.

Thanks in advance

Why not the CGS66?

my personal advice is to buy either two external, linear (not switching!) +15V or +12V power
supplies, which are able to provide at least 500mA, 1A is better
another option is to buy a AC converter which delivers 15 or 12v ac, you can then build the ac to dc converter yourself (see ray's wall wart power supply for schematics http://www.musicfromouterspace.com), both versions are safe
In my relatively small modular setup (2 vco, 2 filter, 2lfo's, 2 envelopes, s/h..) is use two external 12V/1A linear power supplies which work great!
Just remember that stable power supply is very important on a analog synth!

I use PowerOne dual output linear supplies, like their HBB15-1.5-AG (adjustable between 12 and 15 volts, 1.5 amps). they are easy to come by surplus or on eb*y, cheap. either the CGS or MFOS boards are fine, but by the time i source the transformer and all the parts it's not much cheaper. having solid, clean power is a good thing.

Thanks for the replies. Because of this thread, curetronic got in touch with me. Apparently my order ended up in the spam folder.

I also got some good advice on the chat of this site.

If curetronic can't help me, I'll probably build one myself. But I'm trying to find something that isn't kit. I got 4 untested modules that are ready to be powered. I don't want to blow a fuse by making a noob mistake.

These are alternative options that got suggested to me:

Thanks for the help.

why no switched PSUs ?
was there not a thread in the main DIY section where some geeks ( statemachine? ) stated that modern switching PSUIs will do the job ?


whats the advantage of lienar PSUs ?
are those little boards from CGS giving a linear PSU ?
