Speaker pop when relay engages. The relay engages at about two seconds from turn on.
Otherwise no issues. This thing sounds awesome with HPM-100s.
The following work was performed based upon much reading on this forum. This is a fully recapped unit, all based upon what was original to unit. C23 is 470uf 6.3v based upon spec. All SA726 and SC1313 transistors have been replaced with ksa992 and ksc1845. Transistors 27, 29 and 31 in protection circuit have been replaced. TR27 had been previously replaced and the trace damaged, but this has been fixed and a new ksc2383 transistor installed. Relay has also been replaced because former was worn. DC and Bias have been checked and set.
Any help is greatly appreciated...
