Hi all,
during my last waiting time in the lounge in Dubai, I came out with this idea to decouple the power supply of stomp boxes in order to avoid hum-loops. I've done some sims I want to share, and ask if someone else has done something similar.
Basically from one single tap we can get:
- one main output, directly connected to the tap, for the high current requirement (around 1 A);
- as many outputs as needed decoupled by a couple of 220 uF 25 V bipolar caps, then to a regular power supply with low current requirement (I've simulates a CCS with 100 mA here).
Then of course a standard 7809 (/12/15/18) and then 100 n to the stomp box.
The sims has been done with 14 Vrms as a voltage supply.
Has enyone done something similar?
