I replaced R15 with a trimpot to find out at what value the signal was loud enough and clean enough. My experience was that the BBD was getting too much signal and that was causing the BBD to distort. This is what I posted at Madbeans forum a while back: Is r15 the resistor to be replacing or should there be a resistor added between c15 and r15? Thanks guys. I threw a 56k in place of r15 but didn't notice much difference. Fixed the oscillation problem with a larger resistor but am still laving issues with the distortion. Anyway, same problem with the distortion and too high of delay level marc noted as well as the oscillation. I would use the V3205's again if I would build it again.īrian or Marc or anyone else for that matter, I used the v3205 for my build and am starting basic with one chip before doing the addons. It is on my pedalboard that I use for gigs all the time. Very warm sound and with almost noise free. I have a combination now that works but I still have modulation even when the depth pot is at zero.

It works but the speed cuts out on the fastest speed and for the right depth range I have changed a few LDR's. I am still fine tuning the modulation board. In any case socket R15 would be my suggestion. Maybe this is because I used the V3205's. Now it is not distorting and I still have enough delay level. I did it by ear using the instructions from the BYOC board ( see somewhere back in this thread) Initiatly the dealy sounded distorted so I trimed back the level going in the BBD by socketing R 15 and using a temporary pot I found out that 56k was a good value for me. It takes some tinkering to adjust all the trimpots. It has a nice long delay time with the double time board. I have used V3205's that I ordered with Banzai at that time.

I have build this with madbeans pcb and abfackeln's mod board and double delay time board. Where has everyone been getting their BBD chips?

Is this working as well as the MN3205? I have a board and am getting ready to build it up. Soggybag wrote:Sounds like lots of people are building this with the Cool Audio v3205. There is only one deviation in reading: NE570 pin 10+ 11 read 3,5 volts where it should be 4,1 volts. Is it possible to reduse the gain of the transitor stage (Q2) to reduse the gain going in the V3205's?Īll voltages read as posted elswhere. Could it be that we are driving the V3205 (in my case even two) too loud in this build? I do know that the delay should not be completely clean but this distortion is too much. That made me think that the delay signal is too loud because either the signal from the NE570 to the V3205 is too loud (which would explain the distortion) or the signal coming from the V3205 to the NE570 back is too loud (which would not explain the distortion). I accidently turned Q4 around and although that should not work it brought the signal to the right level and also the feedback was reacting better. Also I have some distortion on the delays.Īlso the feedback starts oscillating at 1 o'clock. Mix at noon puts the delay signal already way above the dry signal.

It is working, but I have a delayed signal that is louder then it should be. I have used the double delay time board with two V3205's, MN3102 and NE570. (Posted this question at Madbeansforum a few days ago but have had a response yet. I have build the aquaboy based on Madbeans PCB.
