To be fair to Supratek, the later units are better built than earlier ones. Early ones were a complete and utter rats nest of bad connections, poor grounding, and downright dangerous wiring.
However they are still not very neat and tidy inside which does lead to problems.And like Chorus above, I’ve a higher percentage of Supratek, than Atamasphere.
You can see what a new one looks inside here (at the bottom, left photo) on my website. Full disclosure, it's compared to my lower priced preamp.
