I see a lot of comments on locating these ICs. Did anyone find them or figure a solution or substitute. I'm working on one at the moment and so far I believe I have isolated it to that point. I have signal at pin #2 on I3 "SE540L" (non inverted input but has a little tremolo effect in it) and the output transistors are testing good. I checked them out of the amp and reinstalled them. I'm just not getting any signal output from this SE540L. I see one instance where a C540H was used, is that correct? How about the availability of that one. If I'm not mistaken it was chicagobill that got that guy headed in the right direction in that area. This unit still has those white diodes with the red band on, how important is changing them out with either the 1N4007 or 1N4005. Also I have a note on the schematic to add one of these diodes from pins 8 to 9, any idea what direction that would be or maybe the nessesity of this? Anyone have any thoughts they could share other than making this an end table or night stand. Thanks Steve C
PS: Still waiting on the chassis for the Franky I'm restoring. I'll keep ya'll posted on the outcome.
