Be sure to clean the function switch real good.
After that its a case of injecting or tracing signals. After the pre amps there will be a coupling cap to the PA's. From that point everything is direct coupled so things get a little more tricky. Run it a few minutes & see if either channel is getting hot. When outputs short often the "bad" channel sounds better. The "good" gets low B+ & barely works. Confusing ! A manual would be nice but in the amps the mirror image makes things quite doable. BTW with direct coupled PA's its best to change all semi's & lytic caps in the bad stage. If you leave a leaky transistor behind everything goes again. Especially on high power amps. Takes a microsecond to blow everything out again. 73 Zeno LFOD ! |
