probably spent too much time with the solder pump trying to desolder it, currently looking at ways i could fix the traces

i was usually soldering with 320 celcius. could that be too much?

it isnt solder but rather parts of the rings around the legs that dissolved into each other, i have no idea how i managed to do it

i tried, didnt work, its just a very thin and sticky layer of solder that wont go off

Hey, i accidently created a solder bridge between the legs of the lower bc557b that i cant desolder no matter how hard i try. can the grhv function normally like that?

thanks

is powering the grhv without a heatsink for the c2m1000170d and 10m90s OK if there is no load connected?

that was super helpful, thanks. i bought some ksc5026m off aliexpress but i couldnt find a transistor tester at the electronics store so i bought some BU2508AF as a replacment . if the ksc fail, could there be any harm done to the rest of the circuit?

is the BU2508AF a good replacement for the ksc5026m on the grhv?

is there any benefit for going higher than 400v? (for the carbon)

is 550 pulsed 475 continuous VDC good enough for the big caps on the grhv?

anybody has the left and right 1.8 grhv boards for selling? i dont mind which variant it is

do you think the rk27 is good enough? im going to feed the carbon only 2vrms so the pot shouldnt be turned too low

well my dac is 16bit so using a digital volume control means losing information unless the volume is at max (to my knowledge digital volume control works by reducing the bit depth, and anything below 16 bit means losing information)

hey, which stepped attenuators / potentiometers are a good option for the carbon? most people use rk50 but thats too expensive for me

can someone please explain to me what is the 7815/grlv used for on the carbon?

does anybody knows what this is? i found it in the schematics google drive under the name goldenreference2

im a beginner here too and from what i understand you can either split the psu into 2 boards or use 1. the amp needs 1 pcbs per channel so 2 pcbs in total. i would like if someone could confirm this though

im almost certain i clicked these exact links before you sent them to me. thanks anyway, ive been looking for the schematics forever

it didnt let me view it earlier, saying it requires permissions along with a prompt to send a permission request. i can view it now though, so i guess my request was granted.

hey, i wanted to build a kgsshv as a fun project but since i am a beginner i figured out i would be better off starting with something more simple. so, how do i start? also which tools i need for the measurements and building? (sorry if this post is redundent)

why do the link to the schematics require permissions... i dont get it
