Terry do a listening test to Kypton-v
Hi Thimios,
I tried the Krypton with the latest changes. Bad oscillation and surging. I didn't have time to trouble shoot. I will try again after the holiday.
I also listened to the Eyesee. Very underwhelming. The output is low so that may have something to do with it. I will look into that after the holiday as well.
Blessings, Terry
My friend, this problem is yours .Krypton-v is rock stable(tested).Hi Thimios,

Eyesee is a working IPS also.
Sorry Terry ,i mean that problem isn't at designing.Yes, my problem, not yours. Eyesee works, just underwhelming.
I will have to look it over. I may have csp hooked up incorrectly now that i removed the super pair.
My bad English.....
Yes, I know yours works. I haven't had time to trouble shoot. I didn't think about the CSP until now. I'm in bed so will have to check later. Same with Eyesee. It probably needs some adjustment. I didn't have time today. We have been very busy with the new grand baby and the holiday. I'll try to sneak some time to investigate.
Edit;
It was bugging me so I went out and got a board. Csp's are correct so It must be something else. I'll report back when I've found the problem.

You better stock up. On Semi TO92s are obsolete. I've always preferred their products too.I use OnSemi BC5xx because they are faster at RF in a subltle way that sometimes improves stability, although for most circuits it probably doesn't matter.
Spring for a Luxo with the extra dioptre and SMT is easy. I like the look of through hole devices though.
But imagine some of the 80+ device IPS's (kyptonV , spooky) on 76 X 50mm
"mini IPS's". The low Ic of my IPS's makes for perfect SMD creations.
Some passives would still be through-hole (big caps).
PS - I chose my IPS's .... Spooky and wolverines for main stereo use (i'll compare),
and the symasui for the sub. Using my 2sa1673/sc4388's for the sub - lower Ft (20mhz) but higher SOA than the 0281/0302's - 4 pair for each of the 3 amps.
Stuffin' away (while eating stuffing ) - had most of the OPS devices.

Congrats on grandchild , terry !!
Hey ... we need to "slow down". I'm sure it's as hard to build 2 new amps a month
as it is to to design 2. I intend to be much more careful on any "blind" design.
BUT , soon I will have "sight" with my new testing jig (the 4th unused slewmonster).

Me too!Congrats on grandchild , terry !!

It is time for "slow down"
I have a big difference measuring voltage on Wolverine IPS and i want your advice,i report again about this.
We need an smd board designerNo better time than now to go SMD.

Of ALL the IPS's , Wolverine is fully CCS based .... should be the most rail
independant , "locked in" circuit of them all. (thermally , as well).

Don't be affraid by SMDs. They can offer a lot of advantages*, and no problem with a good glass magnifier and some habit for the welding.My ancient eyes will not permit such strenuous activity at this juncture in life.
*Better parts, less parasitic inductances and capacitances, less box volumes.

If Ostripper came up with Jfet input like BF862 or j209, maybe i will make smd board
I have redraw CFA-X BV Mod, Eyesee, Kypton C and Kypton V using Eagle.
You have redraw these for smd devieces?If Ostripper came up with Jfet input like BF862 or j209, maybe i will make smd board
