Okay, that makes a LOT more sense that DECremented. ;-)

I assume it stands for "decoupled".

Troubleshooting my 453 (MOD703K) and I notice the LVPS has two 12V supplies
going to the vertical preamps - one is +12V and the other is +12V DEC
(same for the negative 12V rails). The DEC lines are fed through a 10-ohm
resistor. What does the DEC denote? DECremented (not likely but I can't
think of anything else)?
