D-Bag
« on: November 08, 2011, 10:09:04 PM »
I just got all my parts in for the dirtbag delay and i just noticed that on the prototypes there were some larger 1 or 1/2 watt resistors and a big 470uf electrolytic.   Those werent listed on the bill of materials so i'm assuming the new layout doesn't call for them?

the 470uF was probably replaced with a 100uf or something, it's gotta be for power supply filtering.

and 1/4W or even 1/8W resistors will be fine.

The original Deluxe Memory Man ran off 24V AC, so it needed larger value caps and higher wattage resistors in the circuit that produced the +15V and -15V to run different parts of the circuit.

The Dirtbag's power setup is a little different so doesn't needs parts of that tolerance.

Yep, the power section was altered to allow +15 for MN3005 and 9v operation for v3205. So, no power adaptor or positive ground in the Dirtbag.
Things are fine, actually.
