Error with wire "Y" (from rectifier cathode to Standby switch).  Shows coming from pin 2 (heater) but should be coming from pin 8 (cathode/heater).  In the "as drawn" config, the rectified voltage would be passing through the heater element of the rectifier tube.  Should be coming directly off cathode pin 8.

Has this been amended on the official layout?  What is the official word from Nik on this?

I noticed that there is a lot of changes made on the power section of the layout on nicks website. That was for both the Dizzy 30 and the Lightning.

I have not been able to locate on the forum of why they were made and what they do. Can someone explain?

I am getting ready to actually start looking at mine to see where I can reduce some noise.

Thanks,

Bill

Hi Bill,

I contacted Nik about the Y wire in the layout and he said that it doesn't really matter if it goes to pin 2 or pin 8 on the rectifier tube.  When looking at the schematic, that does make sense as it is just for the standby switch.

The new layout also has the heater wires on the first EL84 labelled H H rather than F1 & F2 as on the other 3 EL84s.  I mentioned that to Nik and he was grateful for the feedback and said that he would fix that on the layout.

Cheers,

Crusty
