This is an amplifier made on the schema of Dior WS-318. It has overheat protection and DC output protection.
Transformer used has 200VA and gives +/- 38V. The capacitors have 6800uF capacity (each)
Power transistors used: MJ15003/15004 with load of 4ohm (they work very well – tested with Dali 104 speakers, also 4ohm). In the differential degrees BC556, BD139/140 transistors were used.
As a housing, the Eltry T-9015 was used, the knobs from Diors' ssl400 and the power switch from ssl500.
