Thoughts on making a Custom Amplifier

[Stub Mandrel]

I love the sound of my Joyo BadAss, but it's only 50 watts. In all honesty, it sounds better than my Orange Terror.

 

It doesn't seem ridiculous to think about the potential for re-casing it, substituting a class-D module for the integral Class D output amplifier. Or even building my own valve front end.

 

The £10.999 500W modules on Amazon are probably not a good idea for long life.

 

I see that Profusion sell a 700W ICEpower module with power supply for £223.

 

Price doesn't seem to be strongly correlated with power, so presumably there are other differences (such as robustness, e.g. SOAR protection, thermal performance, efficiency).

 

This 500W module looks like it could be suitable:  https://gb.profusion.uk/uk/icepower500asp

 

Does anyone know which of the ICEpower modules are widely used in class D bass amps? 

 

Or indeed any thoughts on the practicality of this approach?

(I grew up with a father who repaired TVs as part of his business and I have been building my own amps etc. on and off for 50 years, so I'm unlikely to kill anyone).
