Great article, thanks a lot. I enjoyed every moment of the explanation, Great work and thank you for sharing Reply.

If I may offer my observations, which are purely subjective though based and no doubt influenced by research. Alessandro Raco on December 23, at Use the metal tab version of the part. Good luck, Ed Reply.

I will definetly try a build on my own. Could you also consider doing a solid state discrete power amp with dual dc power supply. You use the TF version, why is that? Sound quality is severely compromised when the SPiKe circuitry is enabled, so to prevent this we need a heat sink with a thermal resistance low enough to dissipate the maximum power dissipated by the LM Your email address will not be published.

Pietro Di Zinno on April 3, at 1: It is hard to resist from building this amp: Metal film resistors with a tolerance of datasgeet.

In this arrangement, the heat sinks provide some shielding from the Thiele networks datashset the AC wires datashert to the transformer:. Maybe it helps other people with similar questions. Most designs have extensionrods are used between the pcb and the controlknobs at the front, to obtain a better internal layout. If not a full post cover it, could you at a minimum post a link to the pcb?

The thermal resistance from the heat sink to the ambient air.

Rb before Rin or Rin before Rb? Keep all unregulated storage caps close to the LM with proximity based on parasitic inductance daasheet. The LM has one negative power supply pin pin 4 and two positive power supply pins pins 1 and 5. Do you think you could post the exhaustive list, brandd and referenced of the components?

Many thanks too for the fantastic links. Im beginning to not trust this beast. The heatsink is huge. George on December 10, at Under normal operating conditions, low voltage ground loop currents flow through the resistor R1 to earth the chassis.

The components on the PCB layout match the schematic above. Chip amps sound mediocre Reply. I would also like to see a follow up post with details on the power supply.

I had the same, and i placed the order anyway. Consent to store personal information: Hi everyone, Why nobody from Circuit Basic answer to this post, this will be helpful for other who are also confuse with this mater, again: I have a question though. So depending on the capacitor supplier used, the design may have larger bulk capacitance, divided into multiple smaller caps in parallel as needed that can satisfy the RMS ripple requirement.
