3 diff BBD types on Aquaboy 2012 ?

[artstomp]

..I want to build the Aquaboy 2012 with double delay but im stucked wih 3 diff BBD types namely MN3205, MN3008, BL3208B on hand. Is it feasible to put a dauhterboard with the combination of MN3008 & BL3208B on top of another dauhterboard with MN3205 ?...i understand they have diff pin assignments and voltage requirements..i guess the clock MN3102 is compatible with the 3BBDs...tnx guys in advance...

I'm pretty sure this won't work, because of the power/ground pin differences. But let's wait for our resident BBD specialist: Scruffie

I've never heard of anyone doing this because frankly... it seems a bit silly, you have a 3008 sell it and buy some 3208 or 3205s or sell the 3205 & 8s and buy more 3008s. The build is just going to be over complicated and you'll loose all headroom benefits of the 3008. Or personally i'd just use the 3205 & 3208 and settle for 450mS delay.

But... I suppose it would work as long as you got the power and grounds swapped for respective BBDs, I haven't thought about how you'd wire it in to the board though... you'd probably need a new daughterboard PCB.
I'm not sure how the Vgg is set up on the Aquaboy either, you'd have to post the schematic.

Analog delays are already complex builds, do your self a favour and make it easier

..i think this is the way to go at least for me...tnx Scruffie !
