Hi Goldfinger.

Would this also work on a PC-244?
Thanks

I think the 244 is similar but not the same. I think it's more like a 146GTL

Yeah, I couldn't find the Cobra 146 GTL HiFi mod thread.
Thanks!

Does anyone have the link to the Cobra 146 GTL HiFi mod - or the info itself?
Still can't seem to find it - not even on Google BTW
And -thank you- in advance.

I never posted up the 146GTL mods. I'm busy for a couple days but I'll take a look at the schematic when I get a minute.
