i am in the midst of making a spring reverb unit, it is my first electronics project and i could use some help from some people who are more knowledgeable on the subject than i am.
i have an Accutronics reverb tank model 8DB2C1D and i have some preamps from maplin. So far i have got the reverb driver, and the recovery amp working, but there are some modifications and additions i would like to add, but don't quite know how to go about it.
For the reverb driver i have used a 1 watt amplifier N48FL (see attachment)
I have got this to drive the strings in the reverb tank quite nicely but only when i power it with a 12v dc supply connected in parallel with a 9v battery.
For the recovery amp i have used a low noise stereo preamp N47FL (see attachment) this amplifies the reverberated sound nicely as well, I am also powering this preamp with 12v dc in parallel with a 9v battery.
i would like to add an op amp mixer so i can control the wet/dry mix using pots. Can anybody advise me on how to go about this please?
i have attached the pcb data sheets and a picture of my project so far
There is another spring reverb thread currently on this forum - have a look at this - and go to the Belton/Accutronics Web site for information and schematics.
