is there a bright cap on these monsters? thanks

well did the r82 mod. placed a 220k // with original. tamed ch3 just rite. lessened the compression and reduced the gain just rite. sounds sweet. give her a better try tomorrow but sounds like a winner so far. thanks

thanks guys. good info.

thanks. gonna try these. i always thought lower values increased gain? these only affect ch 3 correct? how about r82 only ch 3? thanks again

yes your correct. sorry too many schematics. lol thanks

love this beast, but would like to lower the gain on ch 3. anybody know which resistor controls the gain on ch 3. like to open her up a bit with a bit less compression. would like it more like ch 2. r26 affects ch2, so i am thinking maybe r57 or r58 needs to be increased for ch 3. any...

very expensive headphone amp. that is all. thin tone, not bad at bedroom vol but turned up its crap. my 5150iii makes it whine like a little bitch. thus i owned it for a month and she was gone. good riddance. great footswitch though hahaha.

sounds great bro. thanks for your help. i am really not looking for a plexi type tone on my 2100, but just to thickn it up a bit. i am using active pups so snipping zd1 might be a good start. i was gonna snip the + side and see what it does. if i dont like i can reverse it. this does not...

thanks nilo. with the sens knob low the zd are basically inoperable. no? if a guy removes br1. do i have to replace it with something else or just omit it

sorry. i was talking about the neg fback. chilltone states 2 ways to do the nfb, but one way is easier. the easy way is to r6//1.8k. resistor chilltone says this. doesnt mean he is rite though. (2) make it louder: the NFB on the 2100’s, both MkIII and the SL-X is a lot more than other...

thanks i think a bit more focused sound would be what i am looking for. can i leave the plate resistors alone and just do the voicing mod and tonestack. R20 i think

you sure. it can be done in 2 ways. no worries done lots of this. i can read. thanks anyways. chilltone says differ. https://chilltone.wordpress.com/2013/10 ... odel-2100/

thanks what would you do to v1 and v2?

i understand. its not my only amp anyways. just like to know if it was a easy thing to do. love it the way it is , but you know lol if any updates i enjoy doing them. easy amp to work on. i did replace the can caps, bias resistors and a couple pairs of electralytic caps when i bought it used...

thanks. no problem. any ideas or tips on fattening up the gain a bit. maybe adding a bit more gain to give it a bit more modern grind. thanks for all your help

thanks jake. makes sense man. i do run active pups too. great call. so which is the + side on those blue little buggers? do you have any thoughts on the neg feedback mod?

thanks. by D1 do you mean ZD1 or D1. because there is both. also which is the + side?

you must be talking DR. or jvm :lol: :LOL:

thanks guys. amp does sound great. just thought there maybe something else i would like to try. any thoughts on the neg fback mod? guy states its the reason why the jcm 900 amp is the quietest of the 100 watt line.

here is a pic of what i mean by 2 resistor locations. this guy says to add a 1.8k or 2.2k resistor // to r6. this is the nfb mod
