I did this mod on my DSL50 10 years ago and it's still going strong, glad to see the designer is still supporting his community! There seems to be a resurgence of the classic JCM2000 DSL as of late. (Here is a jcm2000 demo, not my video)
I know this is a musty thread, but has anyone heard from the OP lately? I'm gonna acquire a DSL100 soon and would love to do this mod. I sent an email from the website (which is still live) but I've not received a response.
I tried to contact him also via his website some weeks ago (cause I‘m interested in buying a used JCM2000 but only if I can mod it) but unfortunately got no response.
Might it be possible to reverse engineer it by someone who did this mod? If this might be possible I could order some circuit boards and the parts for all that are interested…
