one more hen's tooth to add to the collection...seiwa ax 99 analog delay

[pinkjimiphoton]

hmmmm, both data sheets show  the same basic cct layout, with a 20k pot.

that said, one says max time of 100ms, the 05 says 210ms. now, i'm running both chips with a 100k delay pot, but it seems to me mark is right...

i should be getting twice the delay time with the 05 still, as it's double the stages.

so yep... i got hosed. i will contact the vendor, and request they re-ship the proper part, or that they refund my money.

Cool, one can buy now exactly that unit (compare the rust above "MIC -40 dB") on evilbay for only $ 125,--:

that's the one i tweaked indeed, the exact unit. i traded it off to this guy for an old guitar.
