My 2SK60 build is still working months later, many hours of use, will wonders never cease? I have never taken it out of the system since it went in, other amps are feeling neglected.
I noticed R1 and R2 called for metal film... In Deleting R1 and going with a 2 in parallel at R2, I have some wire-wounds, are they okay, or should I order a metal film for that use?

some people are not hearing difference between WW and MOX, some people are hearing difference between MOX and metal plate
I made amps with WW and I was happy
if you have those, use them, replace once, if ever

I always used MOX it that job in the past. I went ahead and ordered the Panasonic as I like those and there were only 100 left, so for $20 bucks I snarfed them up. Should anyone need them here, let me know and I will fix ya just pay the shipping. (1.5R 3W 3% MOX)
I think I'll install the WW and listen for a bit and then go back to the MOX and see if I can here anything. I can put them on the Pan distortion tester too and see if the wire-wound is causing any strange happenings.

yes, through this place, but only round 3

Okay, I'm confused:
From Pops, for N Channel OS2
"You can use the diagrams from the original articles for the wiring connections, noting that on the earlier boards the signal inputs are labeled D+ or D- and on these boards they are called out as I+ and I-, otherwise no difference."
No there is V+,+0, +I, -0, G,G,G.
Can someone tell me what the deal is with designations I can follow please. I must be brain dead, but I'm not getting it.

V+ = Voltage + (psu)
+0 = Speaker + Output
-0 = Speaker - Output
+I = + Input (from FE)
G is ground
You are referring to this schematic, yes?
+0 = Speaker + Output
-0 = Speaker - Output
+I = + Input (from FE)
G is ground
You are referring to this schematic, yes?
V+ & G = power supply input to OS2
0+ = Speaker positive
0- = Speaker negative
I+ = positive output of the front end to the positive input of the OS2
G = negative output of the front end to the negative input of the OS2
The P channel and N channel lottery amp output boards use D+ and D- for inputs, the OS2 boards use I+ and I- (G).
edit: I'm always late to the party these days.

Okay, so the signal and supply are sharing the same ground? I ask because I not used to doing that.
Thanks guys, I just couldn't get my mind to wrap....

@6 Yes, that is the one I was looking at. You changed your post, but what you guys told me got my head back thanks.

Yes. Ground is ground.
The exception in this specific case is the speaker negative is not taken from ground, but instead from -0.
