It's a craftsman from sears like 30 yrs ago and probably more for car electronics. I can make a video. Yes, the AC was 0 on both +/- 15vdc adn +/- 18vdc when the fuses were dead. I have a tech 2 hours away with a scope, he mentioned that to me earlier when I reported to him my findings. He said...

Okay, new fuses are in, and rechecked voltages. *Pins 1/2 (positive probe) & 8/9 (COM probe), this should measure close to +15VDC, and 0VAC (this is the positive audio power rail) +15VDC VAC meter jumps around from 29, then 5ish, then 0 and cycles that way. *Pins 14/15 (positive probe) & 8/9...

Will do! I have the fuses on order and should arrive tomorrow or tuesday. I’ll recheck it and report. Thanks for your help!

Bingo! F1 & F2 fuses are blown!!

Thanks. I’ll check them now and report back.

Okay! I measured all according to above and all is to perfect voltage except the +15 and -15 DC voltages! (Pins 1/2 - 8/9 0 DC, 0 AC; Pins 14/15 - 8/9 0 DC, 0 AC)

Here is the pin out diagram to the mixer from the PS

And yes, we had 20-50 mph winds on Friday and a bank of storms that went from west to east later that day. Didn’t do much here but did a bunch of damage when they got to the flat lands on the east side of Arkansas and Missouri. I didn’t price any brown outs or power outages. Although we have...

No spare power supply, that’s how I got the extra console because it didn’t have one and they couldn’t test it.

Thanks for your reply! I have the manual with schematics. I have a multimeter. I reset the umbilical on both, opened up the power supply to check fuses. All were good and it looks clean and good in there. See pic. Where do I test the “rails”?

Hey, @sweetbeats, I hate to bother you with this but I really have no clue what is happening. I hope it's some stupid operator error. I've been running my M-520 for several years now, perfectly, only a few scratchy pots from time to time but never any issues with sound output. Last night I was...

Of course I realize you said "inexpensive" but I love the Zoom LiveTrak products. I've owned the L12, L20 and just recently bought the L20R rack mounted version. I use it on my synth wall to catch spur of the moment ideas in multi-track that I can then use on the computer to build tracks, if I...

I had an Epiphone Les Paul Deluxe Studio plek'd at Sweetwater, it came back in worse shape than I sent it! It's more than the machine, it's about who the tech was and how much experience they have and care they take... they didn't much of either. I had to fight to get them to refund me. I...

I was super happy to find one of those “enthusiasts” that bought it for more than I acquired it for, knowing how to fix it. The Tascam 32 has been a good “pro” level machine for me in my studio. I have it connected to my M-520 console and can record anything that comes through the board in the...

thankfully I sold that unit and purchased a Tascam 32 that is working perfectly for me.

I used a 388 exclusively in Studio C at the studio I worked at in the early 90s. I recorded young bands that couldn’t afford the 24 track big Studio A. It was fun and I mostly recorded them live to the 8 tracks (usually 3 piece punk pop and grunge bands back then, a few rappers with someone beat...

thanks! I have yet to get another recording of this, just no time the last month. Hopefully soon! YES! That TLM 103 is my favorite mic I own!!

Welcome Wendall! As Spantini asked: analog or daw or hybrid?

Just curious, as a fellow M-520 owner, did I just get lucky with my lightly used one? When you talk about the general noise floor of the console, what are you hearing? mine is super quiet, I don’t hear anything more than the occasional trim pot or assign button that needs a little cleaning. I...

I love my M-520. I haven't even re-capped anything in mine and it's quiet as a mouse! I don't know what measurement your statement is based on, but I'm just not seeing it with mine. To each their own, of course. I only paid $150 for mine in near mint condition, so I guess I got lucky and count...
