Asking on behalf of a fellow member on another electronics repair forum. He seems to have a bad a resistor that is some type of 1/4 resistor that is right beside the bridge rectifier. Obviously, these new types of schematics are tough to come by... However, the year of the device is 2007 and all that is really needed is the value of this resistor.

I was just given the Alesis Multimix 8 USB but my friend had accidentally thrown out the power supply with some other old electronics. As it would turn out, this is very hard to find. There are no after-market power supplies made, as far as I can tell. The specs are 18V 500 mA and here is a picture of what I need:
 

My Boss MT-2 Metalzone is behaving strangely on fast cutoffs and to me it looks like the effects of a large cap discharging or maybe a leaky cap. My 5150 exhibits this same characteristic when I take a recording from its Preamp Out, whereas it does not do this when recording from the FX Send instead, so if I figure out what it is I can fix both of them.

Hey guys

First time posting here and hoping someone with some gear-fixing pazazzz can help with my little issue.

I bought an Aural Exciter type C off ebay and when I tested it, I got pretty crappy results.

Hi, I have PreSonus Firepod 8 channel interface plugged into 2 KRK rokit 5 monitors. Every time I turn the volume knob on the interface, my left monitor crackles and stop sounding until I play with the knob long enough so that it's at the perfect spot where I can get clear sound out of it, but it's only temporary until the sound disappears from that monitor again.

Hello audio equipment creepers,

I finally fit the giant Radioshack metal film capacitors into my MXL 991. My mod was based off of this link:http://www.groupdiy…"] Gus' MXL 603 mod[/]="http://www.groupdiy…"] Gus' MXL 603 mod[/].

Hello,

we have a problem with the supply of a TUBE-TECH MMC 1A Microphone Amplifier and Multiband Compressor.
The fuse directly blow for the 240V and 270V supply.
Is there anybody who can helps us with the schematics ?
