For this week's build I went with the Seabed delay as I was hoping it would replace my expensive DM-2W (the sale of which will buy enough components to build about 4 pedals). I'm not disappointed. I got the PT2399 from Tayda for $0.79 and it works great, so no problems there. Overall, the build uses a lot of components (40+) in a small pcb so this made me focus hard on getting the soldering right first time. I found a couple of issues where the stubs from two adjacent components were touching but these were fixed by cutting the stubs closer to the board. Extensive use of blu tack to hold the offboard wiring in place while soldering really sped things up, and I even put the LED in the right way round. I did find that the Tayda enclosure hole for the LED is a bit tight for a 5mm LED so I opened it out with a drill.
As usual, I found that I didn't have stock of one component - C16, a 15nF cap, so I tested some ancient poly caps I had in a drawer and found an 18nF one that tested as 16nF, so in it went.
It worked perfectly on power up, so here it is. I don't recommend using black letters on this shade of blue paint as you can't read it in poor light. Nevertheless its a very nice delay, easy to use, and so its bye-bye Wazacraft DM-2W...
