I think this dates from 1978.
This uses the SAD 1024 Bucket Brigade chip.
The EHX Delux mistress is a early flanger.
Les Paul in 1945 ??
They originally used two tape recorders ... one running slightly out of sync / slower than the other.
From what I've read, the first flanger using an bucket brigade delay ICs was the Eventide instant flanger FL201 in 1976 This beauty had CV controls that allowed modulation of the effects using modular synths.
The Eventide used two Panasonic MN3001s clocked at 2.7 MHz.
The PCB is labelled EH1318 A which makes it a Version 1 from 1978.
Notice the curled knob with pointer.
with one transistor ... a 2N5087.

DeleteHave you ever felt lethargic, out of breath, and exhausted on a scorching hot day? Perhaps you had been running and giving everything you got within you to perform magnificently while the sun beats down upon your back. After a few laps you start to feel fatigued and in need of a cool breeze. This is exactly how your electronics feel when cooped up in a cabinet without any air circulation. electrical conduits
ReplyDeleteWith all the Do-It-Yourself books, shows and websites out there, you may consider completing needed electrical repairs yourself instead of hiring a professional electrician. Sure, attempting to make the repairs can save you money. However, saving money doesn't compare to making costly electrical repair mistakes that could endanger you and/ or your family's or employees' safety. Even if you have a handyman or friend complete the repair, you still risk having major damage done to your property. 維修雪櫃
