What PSU should I build?

[rufustf]

This is my first post here, and I assume it is an appropriate one, judging from what I've read so far.
I'm not sure how many Ma's my pedals require in order to work. I'd like to build a supply that leaves me enough room to add on. I've got a good plan for a bi-polar supply for the EPFM units I've built, it's the regular 9V pedals that I'm not sure about. Thinking about the reg. power supply project at ggg, but not sure if the 200 Ma transformer will do. The commercial pedals have their specs in Japanese, and, well, my Kangi just ain't up to par.
Here's what I have so far:

Boss DD2 Digital Delay
Arion Stereo Chorus
MXR Envelope Filter
Small Stone Phase Shifter
Homemade tube Reamer
Homemade Super Hard On 2 (2 switchable units, 1 box)
Signal switcher w/LED's

All others are bi-polar. I need to power all of the above & have room to add a bunch more. I know it's really stupid that I don't know the Ma requirements for the stuff I built but that's why I have to ask. If this info has been previously touched upon here I must have missed it and apologize for the redundancy.
Thanks in advance.

well roughly speaking:

Your current rig would probably do about 100mA. still aim for a fair bit more if you can since digital pedals like delays/reverbs can do 50-100mA on their own

First off, welcome to the forum!

If you're not sure about the power draw and can't find it listed anywhere, then you'll have to measure it with your DMM.  Read how to do that in the manual.  

OR... if you dont wanna open up your pedals...

Check the datasheet for your 7809.  Chances are it has an automatic thermal shutdown safety feature, so they're essentially indestructible.  If I'm not mistaken (and I could be...), even if you plugged in a million pedals, probably all that would happen is your power source would shut off.  So, you're probably safe to just add a pedal at a time and play for an hour or so.

OR!

If you're at all worried that 200mA won't be enough power... just use a different transformer!  Again, just check the data sheet for your 7809 to make sure it can handle the added current, and heat sink it.  I just checked the first datasheet i found, and that particular one can handle 1A of current when properly heat sinked.  I doubt you'll need more than that
