Last couple of projects were amplifiers, the Lm 384 and SI-1030gl circuit, all parts were scavenged and reused, except LM 386 which I bought in store.
The SI-1030gl circuit is HI-fi circuit and power supply for this amp is from 27v dc to 50v dc.In my case the amp circuit did not worked properly because of bad power supply so I hope that someone will test this circuit and prove that circuit works properly whit stable power sorce.When I turn amp on there was a constant buzz sound.
Step 1: SI-1030GL and LM 386
A circuit diagram for SI-1030GL and LM 386 amp.
A update will be posted soon and please send feedback (new circuit diagrams, comments, messages etc)
