Title: Total Recall 24V vs 18V
Post by: T_MBaker on February 01, 2018, 01:45:59 AM

Gday all,

I'm just about to start my Total Recall build and I'm wondering what experiences people have had building it for 18V instead of 24V. Any problems feeding the Lm7915 so close to minimum input voltage (17.5V)?? Any other problems come up?

Thanks,
Todd

You should be able to run it on 18v provided you 1) hook it up for positive ground and 2) jumper the 240R resistor (R57). Failure to jumper that resistor could cause the it to load down too much for proper regulation through the LM7915.

Thanks for the quick response Bean. That all seems pretty straight forward
