It’s not listed on the schematic but a 1/2W should be plenty.
ScruffieMemberEcho Flanger, Poly Chorus & Poly Flange are all the exact same circuit.
ScruffieMemberDepends on the flanger, some do have a bit of a longer delay, although probably not as long as you really want as the Poly Chorus (the original anyway, can’t comment on the reissue) in chorus mode has about 50mS of delay but that’s not to say they wont get ‘close’ in the type of sound.
You could mod one to have a longer delay fairly easily, if you find a cheap flanger that uses a MN3207 BBD that’s socketed, you could replace it with a V3208 (available at smallbear) to double the delay time quite easily.
The Minifooger IIRC claims up to 70mS of delay hence why it’s probably worth looking at.
ScruffieMemberMixing something with the small clone I doubt will achieve anything close to what you want.
The only thing that might be a contender (other than a cheap BOSS/Ibanez etc. flanger maybe) is the Moog Minifooger Flanger which I see is only $189, not listened to it but might be worth a look.
ScruffieMemberIs it on its own power supply or daisy chained with other pedals? If it’s daisy chained, give it an isolated supply.
ScruffieMemberI don’t know if it applies to the Memory Boy but in some of the Memory Toys, the daughter board holding the BBDs inside could become disconnected and needed pushing back in.
If that’s not the issue you’ll probably need to contact EHX support.
ScruffieMemberIt already did, the EchoFlanger was the exact same circuit as the PolyChorus & PolyFlange so the EHX XO PolyChorus (and previous big box model) is their reissue, admittedly the circuit isn’t identical to the original pedal but it’s likely as close as you’re going to get from them.
ScruffieMemberOkay well unless EHX made a change I don’t know of (possible) that’s been modded by someone.
Assuming they modded it correctly, your supply shouldn’t have hurt anything.
ScruffieMemberOkay well that’s a 9V DC 500mA Center negative supply.
Does your big muff have this style power connection? http://www.kitrae.net/music/Images_Secret_Music_Page/IMG_2253.jpg i.e is it a big box model and if so did you have to use any kind of adapter to connect the supply or does the adapter have the 3.5mm power jack as standard.
ScruffieMemberTo overcome the size limitations you have to use an outside image host such as photobucket, imgur etc. and then link to the images there.
ScruffieMember9V 500mA DC is fine for the pedal, a pedal will only draw as much current as it needs so a high current supply isn’t an issue.
However, if the supply was outputting AC power rather than DC or its polarity was the opposite of that required that certainly could cause harm.
Do you have a clear photo of the power supply in question?
ScruffieMemberThere is the third possibility, someone attempted to mod it to run on 18V, assuming that’s what it required because of the 2 batteries but were mistaken and it wont work.
Yes if it’s a 2.1mm jack it’s definitely a mod.
Hopefully your repair guy will be able to give a definitive answer as to what’s happening inside as without clear photos of both sides of the board I can only speculate.

Here’s your schematic http://www.freeinfosociety.com/electronics/schematics/audio/pictures/smallstonephasereffect.jpg
The colour switch does two things, increases the sweep width and introduces feedback to the input of the circuit.
Is this a problem the unit always had or one that developed over time? It sounds like it’s just too much feedback causing the issue but if it’s something that developed then that points to a part going bad rather than an issue of your particular unit.
ScruffieMemberHard to tell from those photos but it looks like a 2.1mm jack to me and EHX always used 3.5mm earphone style power jacks. All the photos i’ve found of originals don’t show a power jack.
It’s possible the circuit was revised at some point to run on 18V instead of +/-9V or the owner modded it themselves so that it would work on 18V…
