 The 3080 transconductance amplifier is a great part, not a bad current
 source, but with limited capability of about 1mA or so maximum current
 (15mA requested) and 12V maximum voltage compliance (15mA * 2k = 30V
 requested), so we're required to give up a simple IC-purchase approach
 and "roll out own" with well over 60V total rail-rail supply voltage.
