A new BC550 has been soldered in place and I am now able to adjust both channels supplies.The Simplistic is sat on the workbench/dining room table warming up prior to making final adjustments.
A big thanks for the advices Salas.All being well I will have a listen within the next couple of days;unless I can't wait that long which is a distinct possibility 😀

Yes the p/s and phono are at the moment in cheap boxes from Maplin.All being well I will buy better cases from Modushop or possibly ehay in the new year as the phono boards are a tight fit.
FYI the phono boards fit nicely in a Galaxy Maggiorato GX287 (23 W x 8 H x 17 D cm) 😉
I would advise closed case calibration check with crocodile clips hanging out for smaller form factor cases as the ambient delta will be higher from open case to lid put on.
@ Massimo thanks for the info.They are nice cases.
Salas;yes they are folded alluminium bases with vinyl covered steel tops.
I have the following voltages and wondered if TP1/TP2 measurement were close enough or should I fine tune them closer together.
LEFT RIGHT
VDC 42.4 42.5
G/P 33.2 33.3
TP1/2 3.88 3.71

They look nicely correlating, I would say you better take TP1/2 relation down to 3.4V with open case so to allow for some sliding when the box ambient temperature will go up with the lid on.
Another source for 2sk369bl
Semiconductor: 2SK369BL (2SK 369BL) - N-CHNL/J-FET / 40V / 10mA...
Most known for cd lens (at least for me)

Sorry Salas, it 's a typo error. The K369 bl measured 14.04mA so i gather 10R is perfectly ok.

I bought mostly through ampslab and another member who had a significant stash.
I just ordered 500 more of them from ampslab, and some 2SK170's too.
Doomsday prepping, in case of another GB 😛😛 Not having enough stock of these for GB seriously held back delivery times.
Onto more building discussion 🙂
Erlend, why do the caps have little carpets on them?😕
No % accuracy spec I see. At least you will know the components match between them. Absolute value remains to unknown spec. Maybe you could calibrate against a known accuracy LCR to discover its trends.
I will be testing with modded denon 103. There is dynavector DVX1S waiting on the wing.

Yes China made @ 25$ is prob. not the best money can bay.
I thought about borrowing a LCR meter calibrated from job but with my long projects its nice to have one at home.
Will take the tester into work and test it up against a calibrated tester
