+/- 9v 'high current' supply for SCR

[petemoore]

  Im' not seeing the search function, please excuse this duplicate inquiry.
  I recieved my MAX1044's today !
  I'd planned using on to power up a reverb driver, Processasourus was kind enough to point out that the current draw probably exceeds the ability of the PS Chip to supply it, and would break it...
  So I'm back to plan A or B..C or D
  A...slap two 9V WW's on there..and see if I smoke something...because I'm not real good at 'seeing all' and guess it'd work from what I have been able to think through with it...for some reasons, I'm thinking it'll be a wiring effort that may produce unwanted noise, and knowing it would be 'messy'.
  B...anything else known to reliably do the 'high current V+ / V- supply w/low noise well.
  C...Use TWO MAX chips, one for V+, one for V- ... If that would be to any avail.
  D...get a chip that can supply the necessary current and do a +/- 9VDC supply.
  Focusing today on plan C, because I've got the chips here...does that look like a feasable plan?...if so any suggestions welcome !!

  N/A...I'll do more figureing...

  I see no mention of actual cap values for these voltage converter circuits...anyone here that can recommend values?

Go to geofex circuit sweeping, thats the one I used to power up my lxh marsh sym. +9 -9 from a max1044.

I would convert 9vdc to AC then use a transformer.

The two wallwart idea might not be a bad way to go, since it seems like you may be reluctant to build an onboard PS.  You wouldn't smoke anything if you had one wired + to circuit +, - to circuit ground, and the second one + to ground, - to the negative supply.  It sounds janky, but thats pretty close to a normal onboard bipolar PS, just packaged funnier.

In these situatins (+- 9v) at say 200mA I would use a 10V AC supply (there used to be lots of these for the first generation of modems). Run one wire to ground, then have the other go to + and - half wave rectifiers (with 500uF caps) then + and - 9v regulator chips. Plenty of current available, plus you KNOW it is + and -9V, if that matters!
