Ok, you have tested JLA-800S with Coilcraft ?
The Mosfet is already the Infineon ?
Yes, it uses IPP320N20N3. Lots of output power. No THD measurements yet for coilcraft.
Changes on PCB: some adjustments on component sizes, added header for external zobel resistor. Better muting circuit. Converted some parts to SMD.

Looks great, no heating issues with the irs2092? Or do you have a buffer?.
Yes no heating issues. IRFB4227 is not suitable though since I didn't use a buffer.

I know I have read your ebay page.

Ok cool, but have you make some listening of the JLA-800S with Coilcraft ?
Sonic difference with the JA-800D/250D with Coilcraft ?

No listening and performance test for JLE-800S with coilcraft yet.
I prefer the organic sound of T130-2, but it has higher THD.

Hello Jlester, sonic difference between the JLA-800S and the JLA-3DS ?
Hello Jlester, sonic difference between the JLA-800S and the JLA-3DS ?
The specs for each amp are listed on their respective Ebay pages. You can read them and see for yourself...
Some obvious differences are the input sensitivity and voltage gain

I have already read the page, thanks ...
I'm not sure of that ... the PFFB lowered the gain but also changes the sound , only Jlester can answer to my question ...

Hello Jlester, sonic difference between the JLA-800S and the JLA-3DS ?
PFFB IRS2092 based on liteamp has some advantages.
I noticed better cone movement on my Pioneer sub (wired into 2 ohms) with the JLE-3DS PFFB. It has tighter and more defined bass.
Also on PFFB I haven't noticed sonic quality change when I put a tone control on the front end, it's still very transparent and clear.
But I still prefer the sound of pre-filter feedback IRS2092 (JLE-800S) on stereo listening. PFFB's (JLE-3DS) sound is very clean, though there's still some similarities on the sound signature. For PA where lots of signal processing will be used, I think the PFFB is more suitable.

Ok thanks ... the difference between Pre-Filter FeedBack IRS2092 (JLE-800S)
and Pre-Filter FeedBack of the "liteamp based" is the pre-filter is active with opamp on the JLA-3DS ?

Speaker protection v3 is missing the value of R7 in the BOM. Which resistor should I use?
Hi, Please use 1 ohm 1/4W resistor. Thank you

message box full, however, 0 results on ebay, which is odd, some sort of privacy by country
Yes exactly that ...
Put you brower in english ...
And if you want to contact Jlester for make a deal I have is email.
