Re: What op amps in side the RME firefaces models?
Well, the big chip has its type number in big fat markings on the top there - TSB81BA3.
The smaller chip looks like some TVS array (Transient Voltage Suppressor). The "DL46" markings on the other two are probably the same as the toast one, and indicate it to be either an HDMIULC6-4SC6 or DVIULC6-4SC6, from ST Microelectronics.Last edited by Khron; 03-22-2021, 02:57 AM.Khron's Cave - Electronics - Audio - Teardowns - Mods - Repairs - Projects - Music - Rants - ShenanigansComment

Re: What op amps in side the RME firefaces models?
Have you fixed this, i have the exact same problem , i also have L139 and L138 burnt, i also replaced IC1 and removed (VD1202, L139 and L138) from the board and tried to use X1201 and X1202 connectors but it still doesnt connect with the pc.
Does IC1 need programming somehow?Comment

I have here a Magnum IA.100 which belongs to my parents.
The unit powers on & when the relay kicks in, you get a pop from the speakers (this might sound weird but is usual behavior for this amp). However, you get nothing coming through it from any of the inputs & no pops and crackls from any of the controls.
Because of the sound from the speaker when the amp turns on I have assumed that the output section probably works but I could be wrong & I'm not sure how to test that side of things further.

More eBay specials: this time a Gigabyte GP-P450b 450W ATX PSU for $8 with free S&H. Listed “For part/not working”, as usual. Showed up in a beat up EVGA box without any padding… but that's understandable given the total price. PSU made it out fine without damage. It's a non-modular (yay!), pretty modern-day looking PSU with a black paint and all black cables (meh, not my favorite, but figure it's good to keep a few of these in case I do need one for a more modern PC build, just so my old gray boxes don't look too odd in there.)
And a shot of the label:... -
Hi guys
I have a MacBook Pro A1990 that takes 4.9 Volts and .592 to .615 amps on one port. The other port on the left side power cycles with about the same amount of volts an amps but quickly power cycles. The same thing happens on the other side but opposite. So on the left side the bottom port stays on and on the right side it's the top one. I think it is a CD3215 chip but I am not sure how to test it or where to get one. I have checked for voltage at ppbus_g3h and it has 12.6 V which is also on fuses f7000 and f7001 I checked pp1v2_s3 and it has 1.2 V then... -
Hello
Laptop E15 I5 10gen
Mb nm-c421
I have a problem with the usb-c power dc.
The motherboard start only in one side of the usb-c
Replace the usb-c port 2 times same problem
With the usb-c meter, one side 20v ok, other side the usb-c meter don't come on
Try to test the pin with the Mechanic Tail insertion tester and every pin are ok ?
Can the pd controler be the fault ? Or something else maybe ?
Thx

For today's thread, I have a KingWin ABT-650MM ATX PSU. Official web page with the PSU specs is still up and can be found here:
http://www.rmac.kingwin.com/products.../abt_650MM.asp
I just can't help it when I see a broken / for parts PSU on eBay that's listed for cheap and looks at least somewhat interesting. Well, OK, I won't lie – on the outside, this PSU looks anything but interesting. It's a plain gray box with colorful “spaghetti cables”.
What mostly drew me into buying it is its 2x PCI-E power connectors...
