no problem tooNo problem at all Alfred! I just wanted to make sure that I wasn't supposed to get one. Now the wait for DHL!
I am a happy man my package came today,,well done boys lots of hard and tedious work thank you
So... this was true
So thats what a parcel with paradise pcb s looks like
Happy building
Finished stuffing the boards and currently checking dc op points. As usual i jump into these GBs at the frenzy of the moment and only get to do some reading afterwards
Does anyone have an idea if converting this to a FET input is at all possible? Even at the expense of major surgery? The idea of an even small offset does not fill my heart with joy. Whilst it may not kill the cart, it will very likely cause some permanent magnetisation. What's even worse is that the trimming pot makes a mockery of my Shinkoh loading resistors, being effectively in parallel.
Sorry if this has already been discussed in the monumental MPP thread.

Trimming has being discussed. You need a dummy resistor in the value of the DC resistance of your cartridge parallel to the loading resistor. Then trim the DC, take out the dummy resistor and connect the cartridge.
Yes, it can be transferred to Fet with major surgery but i would not recommend to do this with the Paradise boards.

And you can pack the lower Hfe ones in the mirrors without a problem.
They even work in the input stage although input DC offset will be a bit higher in proportion to the loss of Hfe. Can be dealt with just fine with the offset trim.
The only problem that remains is when you swap cartridges quite often that have a big difference in DC impedance. To fry a cartridge is unlikely though.
