Hello ... I bought an amplifier HQ15 from PPHU ELMUZ & BEYMA PL .... At this event I went into protection ..... I sent to SC Prescom audio amplifier Romania for repair , but they did not fix the fault ..... so I sent this amplifier to PPHU ELMUZ & BEYMA POLAND .. .. They said amplifier works .. Thinking about a cold solder joint ... practically opened the 3rd step and enter the source protection .. Please help me with a schematic of the amplifier to be repaired in Romania and in case you get in protection , otherwise spend money courier .. Beseech you ... I love this amp . Please reply from you , and a circuit diagram . Show More
