Hi everyone....😉
Sorry to introduce myself so late but better late than never.
My name is Ricardo, I am totally hooked on DIY... (I know that now)....
After two years modding, I believe I have one of the best CD53 in the world.
I do know how to study and that gave me the oportunity to understand the principal basics related with analog and digital sound reproduction.
I am amazed with the quality of the information and knowledge available in this forum for free.
I am even more amazed with the unbiased unpretentious and very helpfull people I met in this Forum.
After modding the CDP, I built a Maggeddon for my TT and am waiting for my friends to develop a PSU / RIAA / PCB to upgrade my TT.
Thank you all for the precious support.
Regards
Ricardo

Thank you for welcoming me.
Not everybody is perfect but I seem to bump with the right persons.

TEST:
In my prototype, the base of the positive follower Q19 was connected to the sources of the NJfets and the base of the negative follower Q20 was connected to the sources of the PJfets…. While this method works, there is always a small current diverted from the Jfet sources to the follower’s bases and due to NPN PNP differences, it is very difficult to stabilize the Vds on both NJfets and PJfets.
I hope this new method gathers enough interest to produce a fruitful discussion on how to best “drive” both cascodes simultaneously.
