After a few days of looking he told me they dont really make them anymore.
Bucket brigade delay ic.
Of course they might and he just doesn t know where to look.
It was created in 1969 at philips research labs and works in an.
The circuit is based on the boss dm 2.
This uses the v3205 bucket brigade delay chip to provide 300ms of pure warm vintage analog delay.
Developed in 1969 by philips research laboratories the bbd shuttles a stored analogue signal through a consecutive series of capacitors kind of like a fire brigade hence the name.
The bucket brigade device bbd chip was invented by f.
The bbd is fairly old tech.
Aluminum electrolytic capacitors in the signal path have been replaced with higher quality film capacitors for improved clarity over the original dm 2.
A bucket brigade or bucket brigade device bbd is a discrete time analogue delay line developed in 1969 by f.
I talked to my brother an electronics engineer into looking into getting a bucket brigade ic to build a delay unit for me.

Originally posted by pinkerton i talked to my brother an electronics engineer into looking into getting a bucket brigade ic to build a delay unit for me.
Fortunately by the start of the 70s an alternative was on offer in the form of the bucket brigade delay bbd circuit.
Many of these on the market are counterfeit so we purchased a number of them and individually tested and documented each one.
Teer of the philips research labs.
Teer at the philips research labs between 1968 1969.
Mn3005 bucket brigade delay analog ic.
It s the bucket brigade device or bbd chip the integrated circuit ic responsible for creating the delay effect as well as other time based effects like chorus and flange in these vintage units.
It consists of a series of capacitance sections c 0 to c n the stored analogue signal is moved along the line of capacitors one step at each clock cycle the name comes from analogy with the term bucket brigade used for a line of.
Here s a link from the other chips thread.
What s a bucket brigade device bbd.
So i am very interested if they are making new bb delays.
This is an individually tested original manufacturer mn3005 bbd analog delay ic.
