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.
