Title: Differences in the older ADA flangers and transformer requirements
Post by: MarshallJMP on March 05, 2016, 10:01:08 AM

This was a question of a forum member but i thought i also put it on line as general information.

The first ADA flangers used a SAD1024 BBD chip,later models used the MN3010.Early ones also use a µa(LM)723 voltage regulator while the newer models used a LM7815.But they both work on +15V (did the calculation of the 723).The max input voltage of the 723 is 40V and the 7815 35V.Both need at least 3V difference between the input and output.Since they output 15V you need minimum 18V at the input.Actually 18.7V to be correct since there's a diode in series with the input.
I don't recommend using 35 of 40 V input voltages best is to use 18.5 to 24Vdc.You can also use a 15 to 18Vac adapter but here it would be best to change the input capacitor to 1000µF/35V.

Most of the later model flangers used a build in transformer so there's no need for an adapter.

Hey MJ, you missed an  important  information :

Hey Tomy, what did you drop on your foot ?? A flanger ?? But I know what you mean, these things can hurt allot  :facepalm: .

Yes Richard, you well understood : the ada flanger... the built like a  tank one...the one tone weighting Pure DIE CAST one from previous  century, right on my foot ! And it's really f@€#ing painfull  :facepalm:
