My AM diesels draw a full 2A pulling a 15 car freight up a 2.2% grade.
S gauge Legacy engines will not work reliably at 12V to 14V.

I measured a stall current of 2A on an AM GP35, so I'm surprised at your number unless it's for more than one powered diesel.

NMRRC's S gauge inventory doesn't include any Legacy S gauge. It does not surprise me that such engines have voltage requirements similar to their O gauge counterparts. For us, not having any Legacy engines nor intending to buy any, we can keep the voltage lower and avoid the regulator issue.

As much as i don't like linear regulators ahead of Blunami cards, that may be the easiest and most compact approach for S engines, if compatibility of track voltage with Legacy is required, given the likely current drawn.
