Did the JCM 2K DSL 401 have the dreaded bias drift ?

[JMP/HBE]

I heard the bias drift was only on 100 watt models due to heat on the PCB.

Internet lore always agreed with what you heard. Even the early 50w heads did not have the problem,,,,,,,,but I have no first hand knowledge.

I know that the TSLs had a few issues depending on the year. I hadn't heard that about DSL s

I think it was the same deal with the TSL,,,,,and just like the DSL it was only the full-power heads not the 50/60w versions.
