CE require RoHS compliance. https://www.setra.com/blog/ce-rohs-compliance-what-you-need-to-know

As of July 22, the RoHS exemption for industrial monitoring and control instruments will end. Non- compliant product cannot be CE marked and sold in the European Union or to customers who otherwise require the CE mark.

In other words, the requirements for a CE mark (initially focused around radiated emissions) now include the requirements for RoHS compliance (concerning the content of lead, mercury, and cadmium). If a pressure transducer does not meet RoHS compliance, it will no longer meet the requirements for a CE declaration of conformity after July 22, 2017.

I heard that Electro harmonix paid 450000usd because of an FCC issue but i have not heard of anyone paying any fine because of CE problems.

CE require RoHS compliance.

It makes sense, which is not so usual regarding regulations.

I notice the T4B cell shown in the video of the DIY version has a CE mark on it. How does the supplier manage that considering it contains cadmium sulphide?

Just like Avalon, Chandler Limited , IGS Audio, Klark Teknik , Manley,  Warm Audio (all marketed or known as opto compressors, all available from Thomann in the EU).
They just don't care.

It's a long time I haven't been concerned with regulations, but isn't the presence of CdS an RoHS issue? Maybe CE is not concerned about it...

ROHS is necessary to apply the CE mark:

unless we are convinced that professional audio comes under the exempt heading of "non-road mobile machinery for professional use"

I don't think the KT-2A is an exact copy of the circuit. But removing a tube and seeing what happened is fast and worked for me. ;-)

Besides the PSU and transformers its the same circuit.
