Tubelab Simple SE with two Transformers - Centertaps?

[eddiemeddiem]

I'm building a Tubelab Simple SE right now, and have bought two power transformers... one for the main high voltage and 6.3 V. The second transformer is a 5 V that I've got hooked up to the rectifier filament. My dilemma is which transformer center tap should I hook up to the terminal board, or use both?

After looking on Tubelab's website (wiring diagrams and schematic), it seems that the centertap connector on the board is for the high voltage winding, and none is needed for the rectifier. The high voltage centertap is connected to ground. So, should I simply hook both centertaps to the came connector (ground) or should I just simply tape off the 5 V transformer centertap?

Let me know your thoughts.,.. my guess is to connect the high voltage centertap and tape off the 5 V centertap.

Thanks!

Your guess is correct. Grounding the 5 volt center tap will cause a short unhappy life for the rectifier tube and possibly the power transformer since the rectifier filament winding is connected to B+.

Thanks for the quick reply Tubelab!

I've got another problem now, but it's worthy of a new thread...
