After half year of work, I have finally finished my MC452 copy 🙂 2x500W into 4R and 8R.
I need to find someone with audio precision to get reliable THD measurements, but here is THD in my diy capabilities:
and video how meters works:

Wow, wow and wow! Any internals we can drool over?
This cannot be a DIY! it looks bought. Gosh there is some SERIOUS TALENT on this forum
VERY WELL DONE MAN
Unbelievable! That is DIY on steroids.
What a dedication and what a craftmanship!
Congratulations.

2anatech: evaluating sound is very hard to describe and subjective issue, but it definitely has huge power with no compromises and incredibly low distortion across the range and is very quiet in terms of noise and hum, about >20dB quieter than original mac 😉 and sounds a bit tube-like 🙂 in my opinion it is very similar and "sterile" precision sound as MC275 but more powerful thanks to better dynamic. The biggest disadvantage is the weight 😀 45kg

Not real DIY, but here for complete revision after getting them very very cheap. Two of them will drive my lows when finished 😎.
They are build in 1999 and were kicked in the *** for many years, but they're nearly indistructible - except for the caps. Their lifetime might be reached
(okay, that's sarcasm)...

Depending on the wattage involved, it needs some serious fan cooling in there.
A two-dimensional photo can't really determine the actual size of things.
