Hello Members
Do you think it is worth removing known good transistors form quality equipment? Before sending it off to goodwill or the end of my driveway?
I have many quality made in Japan surround sound receivers I need to liquidate. Denon, Yamaha, Harman Kardon, Kenwood, Sansui, etc. Beyond that most likely 30 more units.
I am on Craigslist every day and nothing sells. Looking at charities like disabled Veterans? Can anyone help with that?
My question is. From my observations the certified original transistors might be worth the effort to extract.
Two of my clients suffer many implications of counterfeit parts. Often in delivered products that fail in the field!
With all the tools I have to get this job done efficient as possible. Is it worth the effort? It looks like the power transistors alone might be worth the effort?
Many of the units have dual transistors, Dual FET's and other desirable semiconductors.
I have a curve tracer, FFT analyzer, Noise figure meter, etc. I could supply test results as an option.
Plus the side benefit of transformers, etc.
Any thoughts?

Upscale models have much better chance to find good stuff inside.. LAPT Sanken outputs, very linear drivers, beefy PS, even binding posts and heatsink.... Definetly worth some effort.
They can be very good as they are, I'm regularly using one rotel av receiver as amp and dac, for background aln not critical listening it is great.
Ask here, these are also great when building active speakers... Might be someone closer to you will pay p&p
Budget models however have very little to save from them; bad chip amp drivers, 10A darlington outputs, if not all on one chip. To much V in PS comparing to amps capability..
