i think NXP's is the next equiv
http://www.nxp.com/documents/data_sheet/PMBFJ111_112_113.pdfthe 4119s to order is in 1000s reel, the NXPs to order is eta 2016 end of jan
i think this is all that is left with 40Vbr, https://www.fairchildsemi.com/datasheets/2N/2N5460.pdf --> 5462
ah P channel, wrong item ops
searching 1 tier lower, Vbr 35v, i get mmbf-J112/J111 from fairchild <--- i think i could either try this or wait for NXP
but best search result is the vishay, in the form of LM399 !!!
yea i know, logging anything in this state is pointless, but there is nothing else to do with the DMM atm. but i dont mind saving some "broken" data just to know it
i made some more measurement of the floating voltage
DCV 100mV, DMM = 3mV DC, uni-T = 140-150mV AC
DCV 1V, DMM = 4mV DC, uni-T = 135-145mV AC
DCV 10V, DMM = 4mV DC, uni-T = 135-145mV AC
DCV 100V, DMM = 2.5mV DC, uni-T = ~110mV AC
DCV 1000V, DMM = 2mV DC, uni-T = ~110mV AC
ACV 100mV, DMM = 23mV AC, uni-T = ~21mV AC
ACV 1V, DMM = 22mV AC, uni-T = ~20mV AC
ACV 10V, DMM = 27mV AC, uni-T = ~23mV AC
ACV 100V, DMM = 77mV AC, uni-T = ~21mV AC
ACV 1000V, DMM = 0.71V AC, uni-T = ~21mV AC
the pic is a screen grab off a low end dso, it is also the waveform i remember seeing going around the Q101/102. now that i recall these, i think it might be leakage from ohm source.
it seems net144/net140, which goes thru U107 to net145, could be the source of the leak, if gate leakages are the source.
