Has anyone successfully swapped in a Russian / Soviet 5C4M / 5Ц4М rectifier in place of a 5AR4?
They claim that it is equivalent, and they're cheap as dirt right now compared to 5AR4/GZ34 which are starting to get ridiculous.

The 5C4M or 5C4m is a lower power version of the 5AR4. 140mA as opposed to 160mA for the GZ34/5AR4.
Otherwise it is sensibly equivalent to a 5Y3GB.
