never heard of -5V supply lines...
you probably meant -12V, which is quite common for opamps and I‘d expect that on the cards.
(just dunno for sure, but could check... yes, it‘s there: PCI pin 1 (-12V) is routed to IO board header of Pulsar II)


ATX v1.x had -5V supplied to PCI pin #A5, which is ...

Does anyone know if our Scope cards require the legacy -5V rail on the PSU? Corsair just told me their new ones do NOT have -5V.

I took the dead FSP SAGA+ 400R PSU apart to retrieve a Noctua 120mm fan I had installed years ago. Big cracked solder joint failure identified, likely causing the death of my PCI bus/slots. Somewhat perplexed that everything else still works fine. A tribute to Gigabyte perhaps.

All 3 cards function perfectly in my noisy as heck D865 PERL box. If i could quiet it down with a different CPU/fan combo, I'd consider it. My failed system was extremely quiet. What's the consensus on the current quietest and reliable for a dual boot setup?

It’s likely the power regulation circuits (for the slots) took a hit


This was always my first thought but from what? The UPC with the new batteries, the failed original PSU or the new replacement (or all of the above)? I'm leaning toward the original PSU as it failed to turn on multiple times ...

Progress. After many hours reviving my Intel D865PERL system, both my 6 & 15 DSP cards are functioning without ANY flaws on a 16 channel project running a MasterVerb, PsyQ and Optimaster on the entire mix. I will add the 4 DSP card tomorrow and I expect it too will work fine. It appears my PCI slots ...

The PSU itself wouldn't kill PCI slots, but a power spike/surge or other event can compromise the motherboard and that can fry other components. I've had motherboards fail which took out the PSU (rather than the other way around) and this certainly killed components and peripherals (like the PCI ...

dual boot?

if the project or Scope install is reading from the wrong drive, all kinds of mayhem will ensue.


Yes. Each OS is on a different physical SSD and the new install was performed with the other one disconnected. Stable as Mabel for years...until everything went haywire. I should have ...

Some recommendations:
*Don't use an UPS while hunting bugs. Depending on model, an UPS in online mode can also cause pc to crash.
*Don't use the A16, try with onboard ADDA of the pulsars first.
*Try the masterverb-test for some time. Does the pc crash ?
*Try to test in an other mainboard.

I´ve read all the below and there´s no chance to investigate your issues quickly.
Scope cards should be tested w/ another working computer offering native PCI slots matching Scope card´s power requirements.
A16U should be tested w/ a working Scope PCI system.
How to realize ion your end, I dunno ...

Epic Total Meltdown of my 3 card Scope System

System: Dual Boot W7 32 bit W10 64 bit OS, Gigabyte EP35 DS3R MB, 3GHz Intel Core 2 Duo, 4 Mb DDR2 800MHz, Pulsar I, Pulsar II, Power Pulsar w/Z-link, A16 Ultra, Focusrite OctoPre MII, Reaper DAW. (One Pulsar II card died 2 years ago and was replaced. Nice, quiet (Noctura 120mm fan in PSU), stable ...

Thank you all.

I will relay my epic total meltdown of my entire Scope system in a new post soon. I am beyond frustrated.

I don’t see any information on that floppy connector in the Scope manual. No mention in the installation instructions.

Seattle WA. Thanks but I’ve decided to get the Corsair as it’s a zero RPM to ultra quiet model.

What is the small, male 4 pin floppy connector on the underside of my PowerPulsar actually there for? Is it necessary for all uses? 3 card installs? My PSU just died and no new ones have that small connector on the end of a Molex/PATA cable. Easy enough to make but is it required?

Speaking of PSU ...

I have no idea where Paul Tanti is these days. Never have I heard reverbs with such a long, unadulterated tail as Paul's. Absolutely world class. Glad I bought all of them in the early days.

Hi Dante and Astroman. I'm playing more jazz, hollow body guitar, flat wound strings and fairly low volume gigs. No need for attenuation, just trying to duplicate my Scope heaven FX for clean, live, stereo, solo guitar and voice. Not much crunch, distortion or overdrive thrown in the mix ever. I can ...

Thanks astroman. I have been a fan of and tester for Paul’s reverbs from the beginning and have every verb of his. Unparalleled to my ears. As I’m looking for the perfect stereo setup to sonically please me in small, low volume wine tasting room gigs and already have that sound in my studio, I ...

This is a shout out, especially to any guitarists, that might use a single, Scope PCI card for live performance. I get a perfect, clean, stereo, luscious processed sound in my studio through a Marshall JMP1 preamp into my Scope Pro card thru a MultiFX S insert with Paul Tanti's 2032 reverb, Delay S ...
