RecoilMemberQuote:To quote the manual:Quote:WARNING: Use only the 9.6VDC/200mA AC adapter the Holy Grail + comes supplied with. Do not use any other AC adapters. Using other AC adapters, even those made by Electro-Harmonix, could cause harm to the unit, the adapter or you. The Holy Grail + does not use batteries.
However, as far as I understand it, the power supplies are rated for a maximum current draw (somone please correct me if this is not the case). At any rate, your 300mA supply isn’t putting out 300mA all the time, but it can supply up to 300mA. Seening as the HG+ should only need 200mA or less, you should be fine (again, someone please correct me if necessary). Also, to be honest, I’m using the VL Pedal Power and that beast claims it can supply up to 750mA (on the output I’m using to supply my HG+) and mine’s totally fine. I hope this helps!
Please don’t think that the maximum mA a PSU can deliver can or will affect your pedal unless it’s too low. Even with a PSU that is rated at 100A max your pedal will be just fine, as long as the voltage is a steady 9 volt…
You’re right about all other points. The only thing that can happen with digital circuitry is that it simply doesn’t power up. (if the PSU can’t deliver the 200mA the HG is asking for, the PSU-voltage will drop (or a stabillized PSU just stops working). The voltage regulator (if the HG has one) then has too little juice and won’t provide the (probably) 5 volts for the digital circuitry.)
RecoilMemberThanks for your answers!
Oops, i indeed could have found the tube specs myself. Sorry for that.
What does WB mean? The only 12AX7WB tubes i can find are from Sovtek, doesn’t EHX have them in their lineup? Or does the EHX normal 12AX7 also fit?You say six to twelve months, but what’s the lifetime in hours? I mean, using them a lot or normal can mean something totally different for you than it is for me.
(i won’t use the pedal for distortion, but for warming up my synth sounds) -
