A sincere request to everyone..
When you receive the package, take proper precaution and keep it out of reach / sunlight / outside for a few days.
As we never know , its been handled by so many people during the transit period.
I got this idea from TomTest who kept my package aside for a few days before opening and letting me know that everything is correct. Thanks Andre...

I noticed there is no referencing of the heater to ground on the pcb itself? Is this correct?
I recalled a post of Marc’s 15 months ago+/- where he confirmed that is OK and for builder so far does not seem to cause issues.
What are you using for R16 & R17?
Above quote from Marc had me thinking. Since an amp can be without hum with AC heaters.The most recommended modification is to use DC power supply for heaters instead of AC to have a silent amplifier (no hum) as several builders have confirmed

So it struck me that some had isssues. Now. It is indeed no problem because one can still reference the AC heaters to ground with a 100R resistor on each leg.
For R16=15K and R17=10K as per Schematic 1.6.
R18=1K though as on the Rev. 1.6 pcb.
