From the vendor

Enter the Star Chambre, a copy of the 70’s vintage green MXR-118 V1 analogue delay, converted from the 3 x SAD1024 of the original (achieving a respectable 300ms of delay time) to use 2 x MN3005 (or 3205) for a total of 800mS of delay!

Updated build document December 2024, correcting an error on pg 2, paragraph 3, which incorrectly suggested adjusting trimmer 3 instead of 8. Sorry for the confusion!

Also a couple of new part recommendations as well.
