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 .If you can't find more Buying Leads related to your items, why not post your Selling Leads and Products instead? Show More
