Hi M,
The boards I am using are the ones Bas Horneman had done up as a group buy over at DIY. There are some small differences (JB adds some decopling caps, Bas adds a trim pot ect..) but you can take the same hand full of parts and use either with success. JB’s board was not available when I built mine.
Are you sure that JB’s board is set up for the 5687? It has that odd pinout, which leaves it off my favorite list. I will try to check later.If you have not been to the Tube cad site lately, in the last few bolgs there are PDF manuals as well as a big chart of tubes, with recommended cathode resistors and everything. Good stuff…John

Hi M, I looked over at Tube Cad, the 5687 pcb is set to use the 5687 in the output position only.
I have used the 6CG7/6FQ7 and 6N1P for the input stage, with very good success. But pretty much any of the usual suspects will be pretty much plug and play. This has become my main line stage, crappy power supply and all. I use it with my DRD 45’s and I have recently converted my WE91 300b amps to a D3A front end. Sort of a cross between Damir and Bas H. I am using a anode choke rather than a CCS. This is still very much in the experimental stage. I have posted a little over at group build…John
