yeah...and silicon is a major componenet is SS...guess that's for now at least...

I am quite sure the Linn Klimax does NOT use those TDA chips

only the "big" mono klimax is discrete.......

Hello to everybody,

I am not sure if this has been discussed before, but I would like to get a "complete list" of opamp chips used in commercial products. Maybe this can be good for evaluation of typical sound of a chip. And for getting material cheaply (by fleecing old equipment).
Looking forward to a large list ...

Cheers
Christian.

Obviously it isn't easy to get such a list. Most components, where such IC's are in use, are audio systems (multichannel plate amp as component of the subwoofer) and no integrated amplifiers.

Very hard to find are cost-effective integrated amps like this:
Audio Source Amp 100 Stereo Power Amplifier
GRUNDIG RECEIVER 120 hochwertiger Stereo Receiver, Verstärker | eBay
This I don't understand.
Thank you very much for more advices, also with TDA2030, TDA2040, LM1875 and similar IC's.
