Unlike most Creative cards, this one does not seem to have the CTXXXX model silkscreened on the PCB.
Most interesting to me is the 20W LM1876 power amp on the board with it's giant heat sink. I know it's a PCI 128, and it appears that the 5507 chip means it is a 44.1 KHz variant.
Can anyone confirm and provide more details on this card?
The 5507 chip is an Ensoniq 1370/1371 chip. Creative aquired Ensoniq and revamped the chip: "The Ensoniq ES1370 audio chip was renamed Creative 5507 and revised into AC'97-compliant variants, the ES1371 and ES1373, and used for several more years on card and as integrated motherboard audio." So it is a Creative PCI 128 made during or just after the aquistion.

Horun,
thanks! Anybody have any idea on the specs of the built in amp? Can I drive speakers without having to add an external amp? It's hard to find specs on cards from Creative as they seem to have produced so many variants.
I always thought it looks like that card has a cassette tape attached. That's a sizeable heatsink for something.
Looks like the Ensonic Audio PCI that i had in a HP Pivilon back in the day. Its Amplifier was powerful enough to power the POLK Audio speakers that mounted to the side of the CRT Monitor.
Not mine but exactly like it

It was decently loud for the time. I’d have an educated guess of ~2.5W / Channel
Flakes, thanks for the info. Yes, it crossed my mind that this might have been an OEM solution, however I know that my local computer parts reseller puts the price tag style sticker on every item they sell (see rear of card photo). So I'm quite sure it would have been sold as a bare part and it did not come from a big name (HP, IBM, etc) system.
The reason why I mentioned 20W is because the datasheet for the LM1876 says it will do up to 20W. I have no doubt tho that those HP speakers on your monitor were only a couple watts each.
I'm still super curious about this. Of course, I'll hook up some speakers soon to test it out but I've never seen a sound card like this with a built in power amp. It's nifty!
This looks more like the early Ensoniq designs, all surface mount parts... Creative definitely cheaped out as time went on.
SB 128 => "Cards based on the ES1371, ES1373 and CT5880 only. ES1370 and CT5507 chips do not work."
What about CT4810? is it a compatible SB128 card ?

Huh ? Looking for ensoniq es1370 drivers, win98 those with ES1370 do work with the PCI64 driver ;p
Many CT4810's had a CT5880 chip. Some had the CT2518 which is the same as Es1371/Es1373 iirc but there is no DOS support afaik...
Did you try these:

I have one of those.
Back in the day, they were marketed and sold as Sound Blaster 128 PCI, at least in these parts. I still have the original driver CD which came with my card, and that one has DOS drivers, made by Creative.
It's for an Amithlon-Project. I have to be sure that it's 100% "ES1371, ES1373 and CT5880"
