Hi Paul -
I've had some of the Z1 regs on hand (intended for an earlier version of the TP Buffalo dac) for a while, and now finally wish to use them on a Buffalo BIIIse dac and I/V stage. The +15v and -15v will be used as you delivered them.
The other reg, however, is a Z1A set for 3.3v, with the 1w resistor having a value of 4R7. The dac has power requirements of 5.25v at 440ma. Can you suggest changes to the Z1A to change to a 5.25v reg, and to accomodate the specified current draw?
Thanks in advance - Pat
