Quick Question On Deluxe Electric Mistress Voltage ???

[WLS]

I was wondering if  someone could tell me the voltage reading for the 18 Volts Deluxe Electric Mistress right before the voltage regulater and right after the 15V regulater?

I searched the archives and found one entry that stated 25+ volts. I am reluctant to use this as a  benchmark due to the fact that his was not functioning correctly.

Upon reading this archive he stated that he had made changes to the schematic. This may have been his problem.

And their was someone else that had 16+ Volts right after the regulater. 

Again another proplem and reluctant to use.

Thanks!

I don't have one to test, but from what I know...

"The Deluxe Electric Mistress flanger uses two batteries for 18V, but it regulates it down to 12v..."
(from http://tonepad.com/project.asp?id=54)

Does that help at all?

yeah I know my deluxe electric mistress (with the internal transformer) has a 12v regulator in it...and I have always heard they actually run on 12v....

although I HAVE heard that (with proper components) if you run it at 18 you get more headroom....

Sorry, I should have mentioned that I was starting to build the Deluxe Electric Mistress from GGG's sight.

His schematic calls for a 18 volt transformer using a 15 volt regulater.

I am removing the transformer and gioing to try a charge pump to kick 9 volts upto 18 volts. This way I can use the same powersource for all my pedals (at least for now).

I am still waiting for some parts to come in so I started to modify the pcb template to accomadate the charge pump, polorized caps and rectifiiers. Upon doing this and since I never used a transformer (YET) I was  wanting to get the power supply right so I don't ruined any IC's.

Anyway I breadboarded the powersupply and was wondering if my conversion is correct. At first I thought that take it to 18 volts and then add the regulater. But then it hit me that the pedal wouldn't have much head room. So I went ahead and added the two rectifiiers and the two 220uf polorized caps to the the ones I used for the charge pump.

This now brings my voltage up to 26.47 volts before the regulator. And after the regulater my voltage is 14.97.

I am wondering if these are similar readings to an Deluxe Electric Mistress running the 18 volt transformer?

The regulater I am using is good upto 30 volts on the line. I haven't been building pedals very long and was looking for some benchmarks or if someone could confirm that my powersupply appears to be in line.

Thanks
