Hi there,

i'm building a VCAP dock for my DIYMOD and pico i've ordered some 3.3uf VCAPs absently when should've got 4.7uf to be safe. I cant find the imput impedance specs for the pico anywhere and have emailed justin about it with no response as yet. as long as the input impedance is 25k/ohms or above everything will be sweet I read that the AE-2 was 50k/ohms which would be fantastic if the pico is the same. that would make the bass roll-off start at 9.645754138 hz with a corner frequencie of 0.964575414hz. if the input impedance is 25k then the numbers are 19.29150828 and 1.929150828 respectively. both these sets of numbers are acceptable but obviously I would prefer option 1. Do you have any idea what the specs are.

thanks in advance

It seems the dual RK097 w/ switch only comes in 10k and 50k impedances.

thanks mate yes I was hoping he had used 50k and I got an email back from him today confirming this; earlier picos were 10k but more recently (after mine fortunately) he switched to 50k; so bass roll-off will start at 9.645754138, wit a corner freqency of 0.964575414

rockin!!!. thanks for your reply though
