Brice Z6 fretless spalted maple 3,8mA
Brice Z6 fretless Trans Blue 0,31mA cool running bass. Obviously a different preamp or problem on the spalted maple.
Tune Maniac 4 and 5 string ( Korean ) 3 by LF442 1mA
Yamaha RBX800A 4,5mA at 16V(*)
Ibanez SR706 and SR705 ( Korean ) 1mA
Custom 7 string bass ( Korean ) 7,2mA at 18V ( now 16V )
( *) Fabricated a battery eliminator for all the active basses, ( additional 7 basses over the above ) supplies 16V DC. Not all increased current draw at the elevated supply rail. Caveat, watch out for tantalum capacitors in preamps. They do not take kindly to reverse polarity, including a series diode in the supply line of some preamps. You will actually have a supply rail of minus 0,6V ( -0,6VDC ) on the down stream load of the reverse biased diode, enough to nuke a vulnerable Tantalum capacitor ( internal short circuit is first fail condition and then overheat to open circuit if enough power supply grunt ). Also over volting a tantalum is another no no. 18V is not a usual rating for tants, 16V usual maybe 25 and then 35V working volts, plus or minus feed impedance to the capy, for actual supply on capy terminals.
