The vintage and early reissues used a 1/8″ tip positive plug for power. The newer reissues use a boss-style plug with center negative. That’s pretty much industry standard these days for negative ground effects.

The EH ManModeratorThe correct original adapter for that is the US9DC-500. 9vdc, 500mA, 3.5mm plug with positive tip.
Link to Reverb listing: US9DC-500
The EH ManModeratorThis is the correct power supply for your pedal. Not my listing.
For future reference: 24vdc, 100mA, center positive

The EH ManModeratorIf it’s just a 2 position switch it should be fine. I’d take a meter and check for continuity on the closed contacts.
Was the old switch just not making a good connection? I take them apart and clean the contacts with a pencil eraser.The EH ManModeratorSounds like it could use an alignment. That’s probably noise from the delay chips not being properly biased or the balance trim not set

The EH ManModeratorFinally heard back from Mike today. Here’s his reply: “I bought about 100 of these, all black, from Moridaira of Japan in early / mid 1970’s”
The EH ManModeratorPost some pics and I’ll forward them to Mike for more information
The EH ManModeratorMight be a broken selector switch.
The EH ManModeratorHow much for it as-is? Send me an email.
The EH ManModeratorI’d have the footswitch replaced. Sounds like it’s wore out.
The EH ManModeratorI would not touch the trimpots.
Which switch are you toggling to clear up the issue?
