Hi I'm about to melt some solder on a DC 30 build and would like to hear from anyone who has built one. Any suggestions or advice about avoiding problems or getting great sound or any other aspect of building one of these will be most welcome, I have already read a suggestion to get the 10watt resistors off the main board to avoid cooking the board which sounds reasonable, Ill set these on tag boards. I'll be using all Hammond transformers 1750TB, 290MAX and 194E The other suggestion I have heard is to shield the OT to stop the ef86 oscillating, easy enough to do
Thank You in advance

Hi guys. I ordered PCB for Trainwreck. Did anyone built it? What kind of power transformer did you use for it?
Tnx in advance. 😊

Check Tube-town. Sells power and output transformer. I have build mine with them and theyre good.

I’m still in the planning/ordering phase, so other than saying I’m interested in seeing how your build goes, I have a couple of thoughts I’d like to put out there for others considering this build:
Consider using stand-up style transformers. Given the large footprint of the PCB and the number and placement of the tube sockets, you may not be left with much room in many enclosures. I ended up buying Heyboer transformers, which are lay-flat, and from a rough sketch I can already tell things will be tight. That’s a bit of a regret, as I think I may have to elevate the board. Oh well.
Consider increasing the 100 ohm screen grid resistors to 1K, 2/3 W. Current-production EL84s aren’t the most robust tubes out there, and this adds a bit of extra protection at minimal (if any) cost.
