I sent this same question to TC support over 2 weeks ago and have received no reply.
The pedal board I have below is powered by a Gator G-Bus-8 power brick bolted underneath. It has 1700ma total. My existing pedals only use about 1000ma and I've some spare 9v jacks. A Nova Delay is being shipped to me now and I'll replace the DD-6 I have for the Nova Delay.
1) Can I run it safely and efficiently on 9v without causing any prob's.
2) How many milliamps does it use when maxed ?
