Hey all.  I know this isn't exactly a DIY thing, but I didn't know where else to ask this.

I have an old Electro Harmonix Small Stone phaser.  EH4800, no LED and it has the "round nut" on the footswitch instead of a hex nut. 

Above the power jack on the panel it only says "AC".  It looks to be a 1/8th inch mini connector.  Best I can tell it's a tip/sleeve.  Anyone know what PSU this thing takes?  Last thing I want to do it let the smoke out of it!  I've had it forever and for life of me I cannot remember what type/voltage/etc the thing takes.  It's pretty beat up and I'm hoping to get it back on line.

Thank you .... :)
I didn't say it was your fault, I said I was going to blame you.

The original power supply is 9vdc, 100mA.  It has a 1/8" plug with tip positive.

Oh HELLS YEA!  Thanks folks!!!  I've been wanting to get that thing fired up to see if it still works, or if I need to work on it some.  I bought it new sometime around 1980 I think .... I think .. been a lot of blue smoke and fluid intoxicants modifying my brain chemistry since 1980 so it's difficult to say exactly when I got it.  :)

I've got parts so I'll just monkey-up a pigtail adaptor to fit a Boss wall wart .. TIP POS, Yea?

Thanks for the info!  I'll post results of testing in this thread.  :)

Hasta Lasagne!..
