I have an old Proteus module with the classic clicking power supply problem. Dang voodoo power supplies, I hate them!
Anyway, I was wondering if I could simply use a power supply from one of my old computers. Seems to me that +5v, -5v, +12v, -12v from anything would power this unit.

I used to know this. When you plugin a condenser mic to a phantom power source, should the phantom power be off or on so as to avoid damage to the mic? I forgot.

Okay, let's see what you think:

Does power supply really matter?

I mean, I know that surge protection is good, but I see as many guys using $100.00 Furman [sic?] power conditioners as I see anything else.

What do ya'll use and does it really make that much of a difference?

Thanks!

i was wanting to know if i have to record seperately with my condensers that require phantom power than with my dynamic mics that dont require it. my Mackie cfx16 board has one master phantom power switch and it seems like a bad idea to feed phantom power to my dynamics that dont require it. is this true or would i be fine having it on while mics that dont need it are plugged in?

Hi All I am looking for a power amp for a pair of PMC LB1s They are rated at 60 - 250w at 4 omhs.

I have about £300 to spend should i be looking for a Pa power amp - I have seen a crown geodyne 500w for £250 or should i be
looking for an hi fi amp. I know to stay well clear of samson for sure but any suggestions would be appreciated

cheers

I was just looking at the specs on the Behringer ep2500 power amp and I realized it says that baby sucks 9.6amps. Now at that rate on a normal 15 amp circuit that you'd encounter a lot, you couldn't even run 2 of them on one could you? I highly doubt it's 9.6amps continuous unless its pushing max power, right? whats the opinion.

Does anyone here use external phantom power supplies?

Hi

Does anyone know what kind of power supply (trans, gretz, condensers) API built in 500-6B Lunchbox? Any link to electronical data and schematics for that?

API 500-6B and 500H use different power supply. Does that affecting the sound of preamp modules (512c)?

thanks in advance

I've read a lot of posts about wall warts being inadequate for preamps. and I was wondering it that holds the same for guitar gear?

For example. the rackmount version of the Line 6 POD has an internal power supply, and the kidney bean looking one uses a wall wart-esque power supply. Has anyone done an A/B to see if they sound different from one another?

Hi,
Anyone know where to get schematics for repairing keyboards? The Yamaha DX21 in particular. Free would be best.
