Not a deliberate choice, I only had these ones actually. <br />Clean boost until 9 o'clock... Drive well beyond. Maybe too much !? <br />Works very well with a vox ac 15 already slightly crunched but not on an orange Rocker!!! <br />I wonder if any improvement would make my drive more clean until 12 o'clock though? <br />I know 2n5089 have much more gain than 2n5088 but who knows there's a way to succeed somehow ?Johnhttps://www.blogger.com/profile/01191269651713251035noreply@blogger.comtag:blogger.com,1999:blog-6847048658257278783.post-47190822655238268722023-01-29T07:06:03.229+00:002023-01-29T07:06:03.229+00:00Built with a 2n5088 and a 2n5089.

Because i didn't have a pair each of them. <br />Sounds great !!!<br />Drive is more or less clean until 9 oclock, becomes so rich and kind of fuzzy beyond. It's not as transparent as it could be when fitted with two 2n5088 but it makes the job as well. <br />I'll try to make a Switch to Swap the 47k and 4.7k like i read Somewhere to have more flexibility with the drive . Do you think i'm right ? <br />Johnhttps://www.blogger.com/profile/01191269651713251035noreply@blogger.comtag:blogger.com,1999:blog-6847048658257278783.post-24509515559109227282019-11-26T03:49:20.441+00:002019-11-26T03:49:20.441+00:00Nice nice thank youNice nice thank youWahyu ekohttps://www.blogger.com/profile/03327805263279044062noreply@blogger.comtag:blogger.com,1999:blog-6847048658257278783.post-8367344222015340382019-11-26T03:48:03.316+00:002019-11-26T03:48:03.316+00:00This scheme is correct, I am trying to make a sock...This scheme is correct, I am trying to make a socket on a 1k resistor.
