Tea-Bag

Cool.I can send a few sets over as needed. Nobody needs to go without. I can also send over 2 - R085 Depletion type as gift to might ZM, if you wish to expand your big/little donut concept with them.

Zen Mod,Thanks for your work on this. From your previous post #342, looks like you are complete.Doing a few circuit boards, assuming looking for some people to jump in.Let me know next move.

Thanks for the applied science. Let's see if I can dumb it down. So it goes then match some R100's at 2A, find decent matched pair. I'll assume that 1v6 was your vgs. #2 Set to get proper current to CNY pin 1 and across 200r pot. will guess that this pot affects offset. Also, front end Jfets will need drain set with 100R pot (will also affect offset). #3, front end CCS may need to be fiddled with to get 20MA to girly JFETs, too much = white smoke. Does 22r pot help here, or should a pot be in series with 620R? (500r and 200r) This sounds like the making of a Cookbook Someone let me know if I can score good serbian pcb or gerber files. I got JFET's to trade.

: Thanks, do you think matching is needed or best practice here?

:ok:Zen Mod,Did you use matched R100's per channel?

Was thinking about Jfet input front end, and replacing those hard to find P channel Jfets.Some people don't have access to such pricey 2SJ109, and even 2SJ74's are harder to come buy. Sorry to post in English guys, but rather this than offend you trying to translate.

my only thought here is to use if possible a 2sj176, or some P channel critter that doesn't cost $$

Not a problem ZM

Those 804 drivers are very nice looking.
