My transformers are 30Va and 80VA ( 18+18V).
T500mA at 240VAC for those in close fusing or more. They took out a 250mA fuse at start up quite normally.
Hi Salas, is that the measurement btw chassis whilst power on?.The zap was from touching the PSU box.Very probably. The phono and psu boxes do show 10.5-11R between them?
Quan
Either when off or on. Its the lift resistors should show up and between boxes connection confirmed. Still the PSU box was at mains earth, thought you had touched the main one. Anyway. Lets see what higher DL103 loading does for refinement then.
Since the ground side of the psu feeds goes to the channels and there should be two wires from channels gnd marked pad at regs meet phono towards a NON insulated ground lug to TT earth, there should be continuity from one chassis to the other chassis if the yin yang lift diodes at PSU are bypassed by a 10R which I think I shaw a cement one on your pic plus an orange MKT RF grounding cap you added.
Yes , i followed the grounding schematics as per build guide. Hmm?. The ground lift diodesare bypass by 10R/100nF cap.Since the ground side of the psu feeds goes to the channels and there should be two wires from channels gnd marked pad at regs meet phono towards a NON insulated ground lug to TT earth, there should be continuity from one chassis to the other chassis if the yin yang lift diodes at PSU are bypassed by a 10R which I think I shaw a cement one on your pic plus an orange MKT RF grounding cap you added.

The panel you test maybe is floating then. What happens if you test from the TT lug to PSU box?

Measured 4.7R. BTW change loading to 470R, a bit loose for my liking but stage has opened up further .
Quan
4.7R? The TT parallels something also it seems. Or that cap doesn't allow to show 10R. But there you are they are linking. Alright, you could scratch some panels or link them with wire so the whole box becomes earthed for RFI better. DMM on continuity between lug and panels will show which are earthed and which insulated by paint or whatever.
Click in the 1K position 4 on the DIP also to go 320R combination with pos 3 and listen there too.

The front panel probably not earth properly as it is contact via the screws of the main chassis ( painted).

You could link from lug to an eyelet for one of those screws maybe?The front panel probably not earth properly as it is contact via the screws of the main chassis ( painted).

I was thinking of that. It is 11am over Sydney at moment on lazy Sunday- temp 28 C already, spinning some blue notes Sonny Stits.You could link from lug to an eyelet for one of those screws maybe?




Quan
Cool. Its not a pressing issue anyway. Better listen to some sax records and home in to the loading. 1:10 SUTs on MM inputs present 470R to dl103s for instance, but there are more combinations in our DIP selector. Your third party stylus maybe needs something bit different bcs more open than the standard conical. Members will understand much better than theory how to test little aspects we referred to over a finished build through our practical conversation.
Thank you very much Salas. I do learn a lot by building this project. I will keep you post when it settles in and try it on a higher resolution system.

Alright. Things have gone well by now. You got C2Y too to try trim in case it will mellow out much when it settles. Till then happy records spinning! 

Power on the Riaa/Mc. 31 V dc out from supply. The vario is not turned more than 2/3 up. Gone to leave it that way for some hours. The old caps get a soft start and they was on during night to.
Nothing get hot at all. Everything looks allright. Will be back later.

@quan how have you connected the grounding lug? I can't see any wires from the ground point on the pcb's to the TT ground lug on the chassis.
I did the initial picture without the ground wires from each regulator as part of setting up only. Now it is boxed with two wires from the ground slot from each regulator as per build guide.@quan how have you connected the grounding lug? I can't see any wires from the ground point on the pcb's to the TT ground lug on the chassis.
