Yamaha C4 Pre-Amp: Worth Refreshing/Repairing?

[avionic]

Uncle Sam refined my soldering techniques by sending me FTD to

NASA Soldering Training and Certification.​

Glue!
Will need to check to see what all it did once I get a solder station and desolder tools and some practice in.

The glue should mostly chip off pretty easily.

Thanks for your service!

I will order the big power subsystem caps from Mouser. I now wonder whether there is a solid and accessible in public P/L that folks rely upon for parts that are likely bad and/or in need of replacement. Like perhaps some diodes and transistors. Will read more threads and do more searching in parallel with more cleaning of contacts and switches.

I don't replace active parts unless they are bad. (diodes and transistors)
