100W Ultimate Fidelity Amplifier

Thank you for that insight. Just another clarification - if you would please
The BOM for your PCB lists 2 different 100 nF capacitors. One is 250V Panasonic epoxy coated PET and the other is 63V WIMA box-type PET. Any reason for this? Can we use 250V Vishay polyester instead
Thanks

C13 does not see a lot of voltage and a low voltage "small" 5mm pitch 100nf is adequate.

C14 is part of the Zobel and can see larger voltages and currents, so "larger" 15mm pitch 100nf non inductive is more suited
 
Anyone know the replacements for 2SC2690A and 2SA1220A on A40
