Oh boy. Lots of stuff Im curious about here. The variable slope sounds cool. Miles if one was working on PCB 2204 and didnt want to hack up the board could I simply unsolder the wire feeding the slope, come directly off that pin to a 50k pot then go from the pot to the existing wire to slope?Reeltarded wrote:Awesome!
After so many modded versions of the stock circuit I have come to really like these features:
All 2k7/.68u stages (3)
Switchable 500p/1000p/2200p peaker at the entrance of the usual 3rd stage
100p bright cap over gain
CF master (Jose mod) with clipping circuit I like transistors and 1n914s in pairs. I add a 25k or so pot to ground on that control to vary the diode dump. That is VERY cool. Red LED and 20v zener also very good with jist a fattening action without so much dump.
Simple 800 style master as you said above (also)
56k CF
You could wire up a three pos switch to bypass second stage for very plexi, normal 2204, and added stage.
1M/.0047u resonance
Bunches of other stuff..these amps are very forgiving as far as the dress is concerned. I recently started converting my mod amps to rear input to get the input right on the tube.
As far as switching input from hi to lo.. that is kind of the same thing as the two stage setting on that staging switch I was talking abooot.
VARIABLE SLOPE! 33k-83k! Yes!! I'm excited. Let's hurry.
How do you wire the "plexi" switch your talking about?
