Hi Folks,
To reduce confusion and to keep this thread on-topic, I have created a new dedicated thread for the Mark Jonson / Gtose BJT capacitance multiplier here:

Please post subsequent discussions there so that we can keep this thread clear.
How to tell of its not a Juma Easy Peasy cap Mx? It will have 2 BJT’s instead of a single MOSFET and have typically a potentiometer.
Both work well but the MOSFET based one has a slow ramp startup that’s useful to prevent thump on speakers and also easier on electronics due to less thermal shock from turn-on. Essentially a soft start for your amp. It’s not a soft start for the upstream trafo though.
