Review and Disassembly of a Fender Guitar Amplifier

[@brocktechnology]

The tda2030 seams to be widely available from the usual suppliers for around a dollar a piece as an assembled module. Digikey says the IC is out of stock and out of production, I hate to design a project around an obsolete part even if there's still tons around. The LM1875 looks like a good alternative. Building a practice amp with either of these parts sounds like good content to me.

I can clearly see op amp chip and 2 clipping led's, for overdrive/distortion.

The metal chassis IS a proper heat sink.

[@francisstudiosengineering]

I would disagree - respectfully. I would call it an adequate solution; as it can deal with the thermals of this small IC, but definitely not a nice solution IMO. A proper sized metal extrusion heatsink would cost a dollar or maybe less - that would have been a more proper, less hacky solution than ribbon wiring the IC down from the PCB.

By proper I really meant an aluminium (or whatever other metal) heatsink as it's custom in HIFI amps; maybe mounted on the PCB. Something that does not just work, but there is a little bit more design invested into it. These were my expectations, but the reality was a little bit underwhelming, so that's the reason why I would phrase it as "non proper".
